The wallpapering technique is a key protocol for extending the function of endodontically treated teeth. More brittle due to their reduced hydration, non-vital teeth are more prone to fracture, so using fiber in this way creates a fail-safe that prevents failure beneath the coronal portion of the tooth and reinfection of the root.Dr. David Alleman discusses how he helped pioneer this technique and other advancements in adhesive dentistry for cases with non-vital teeth in his Six Lessons Approach to Biomimetic Restorative Dentistry.Articles referenced in this episode:Deliperi S, Alleman D, Rudo D.

Dr. David Alleman first created his Six Lessons Approach for vital teeth, but the same conservative principles can benefit endodontically treated teeth too. Compared to traditional techniques for retention and bonding, the advanced adhesive and stress-reducing techniques of biomimetic dentistry are better suited for treating non-vital teeth, which are more brittle and susceptible to cracking than fully hydrated teeth with healthy pulps. This episode outlines how biomimetic techniques approach endodontically treated teeth differently and the research that supports these protocols.Articles referenced in this episode:Kishen A., Vedantam S.

How to whiten your teeth naturally at home? Are you looking for way ways to whiten your teeth? We found 9 methods that you can try at home and that won't do you any harm at all. If you follow this advice on a regular basis, you'll see your teeth lighten up a few tones! TIMESTAMPS DIY whitening toothpaste 3:16 Tea tree oil 4:30 Strawberry paste 5:26 Coconut oil 6:27 Activated charcoal mask 7:08 Banana peel whitener 7:50 Lemon mouthwash 8:41 Basil leaves 9:10 Aloe vera 9:50 SUMMARY First of all, it can be genetics. This one is hard to beat. Yellowish teeth tone might be just a thing in your family, and you inherited it from your parents. Don't blame them. They also gave you a sharp mind and beautiful eyes. Second, it is certain medications. The antibiotics doxycycline and tetracycline can even darken the teeth of children under 8. Research has shown these medications can even affect a baby who is not born yet. If your mother took them in the second half of her pregnancy, it might give you permanent stains on your teeth as you grow up. Dentin is also to blame for a not so white smile. It is a material, which lives under your enamel. When the enamel is thin, you can see the dentin. It is that deep yellow to the brownish color we hate to see on our teeth.

Caries removal can be reproducible — this means consistent regardless of patient or practitioner. Caries detecting dye is essential to creating reproducible caries removal endpoints, but the techniques doctors pair with the dye are what prevent pulp exposure and maximize bond strength.When Dr. David Alleman pioneered his methods for determining caries removal endpoints, he found that any doctor he trained could achieve the same predictable caries treatment that he saw in his own cases. How caries is treated is the first step in a restoration and determines whether that restoration succeeds or whether that restoration fails.Article referenced in this episode:Anderson M, Charbeneau G.

Immediate dentin sealing is a commonly known technique even outside of advanced adhesive and biomimetic restorative dentistry. Originally developed in the 1990's to solve the issue of temporization contamination, its uses once refined were immense when applied to dentin adhesion. Yet for doctors currenting using immediate dentin sealing as part of their restoration protocols, there may be more benefits left untapped when not used as part of a larger system of protocols that aim to mimic the natural function of a tooth: the Six Lessons Approach to Biomimetic Restorative Dentistry.Dr. Alleman discusses the history of immediate dentin sealing, its early pioneers and how doctors can use this technique in their own practice to save pulps and maximize adhesion.Publications discussed in this episode:Paul SJ, Schärer P.

Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is: Another medical miracle, published by Dentin on June 25, 2023 on LessWrong. Or, "How I became even more disappointed in the medical practice in the USA than I already was". I'm getting older - half a century now - and have recently been having health problems. It started with soreness in my right hip about four years ago, gradually getting worse and worse over time. At one point I damaged it by sitting in a funny position for too long; later on, I did what I thought was a very normal set of lunges in the gym that made me almost unable to walk for months afterward. Then, about a year ago, I started having issues with my feet. At first, they were a little sore. They got worse and worse, eventually getting to the point where I again couldn't walk comfortably. They just would not heal, no matter how much time off I gave them. In the past three years, I've seen half a dozen doctors. Hypotheses ranged from early onset arthritis, to joint damage, to tendon damage, to disc compression in my back. Physical therapy helped a small amount, but the gains tapered off quickly and did not last. I was making no progress, and had simply restricted activity in my life to the point where things were tolerable. None of the doctors had any idea what was going on, and every visit was hundreds of dollars to be told things I already knew. One doctor prescribed exercises for the elderly to build muscle tone, without even bothering to ask about my current exercise regime or current state of fitness. (At the time I could do sets of 40 push-ups and one-legged squats to the floor and back.) To say that I was frustrated is an understatement. A bit over six months ago, I began to wonder if perhaps this was a side effect of the low dose statin I had started taking. The problems started prior to my taking the statin, but I found reports of statin side effects that looked vaguely similar to my issues. Perhaps I had fouled my cholesterol metabolism? I concocted an experiment to stop taking the statin for a few weeks, and eat a ton of eggs to try to get more cholesterol in my system. I didn't know at the time that dietary cholesterol makes very little contribution to total cholesterol levels, but that turned out to be a good thing: I saw what seemed to be noticeable improvement. The next couple of months I learned about cholesterol metabolism and ran more experiments, eventually narrowing things down to the point that I knew statin use was not responsible. The eggs were the active ingredient. But how does that make any sense? At some point it occurred to me that eggs also contain protein, that bodybuilders supplement protein in order to build muscle, and that vegetarians could get protein deficiency. With ten minutes of investigation, I discovered that my preferred diet is pretty close close to vegetarian, and had slowly been shifting to become more vegetarian over time. Did I have a protein deficiency? Lacking any other options, I used the power of "moar dakka" and tripled the amount of animal protein in my diet. Since then, both of my long-term multi-year health problems have gone away, all in the space of the last three months. I can hike for miles again, I can lift heavy weights, and I heal after taking damage. It's amazing. What has not healed is my opinion of medical practice in the USA. How on earth could something like this go undiagnosed for years? How could something as fundamental as protein deficiency not be a standard, ordinary thing we test for? How could half a dozen smart, capable, and highly trained doctors miss something like this repeatedly? How is it that the best modern medicine can do is say "go to physical therapy and hope it gets better"? To say that I am disappointed quite undersells my change in opinion. I previously took what doctors said with a grain of salt but largely belie...

We open the festivities season with a very special mix from DJ, producer and musician Curses, with a dreamy compilation of cinematic elements, radio and tv samples from the 80s and 90s, and an extension of his passion for mixing Wave and the dark and weirder side of Italo Disco. Originally hailing from New York and currently based in Berlin, Curses is well known for blending his Rock & Roll roots with the darker side of Disco and Electro. In both his DJ and live sets. Curses also incorporate his ghostly vocals and guitar with flashes of EBM, New Wave, Post-Punk, and Psychedelic synth vibes. After his debut full-length Romantic Fiction in 2018 on Jennifer Cadini's Dischi Autunno, this year Curses released his second album, Incarnadine, also on Dischi Autunno. His compositions blend Morricone-inspired guitars with elements from early 80s music genres like New Wave, Post Punk and New Beat, pushing the boundaries of these references with an emphasis on his own mysterious vocals and guitars. The album is a dialogue between the inner self and outer, and the romance of eternal and immortal existence. With a big inspiration from the cult classic film The Hunger which explores themes of immortality, love and timelessness, the post-modern vampire film contains a dark glamorous atmosphere. Slick production and dark, grooving melodies push the listener down a sinuous path with nostalgic moody guitars, and haunting vocals. Music is caught in a push and pull between the melancholic beats of the past, contrasted with a contemporary and sophisticated production; the album pays homage to Curses' musical roots and the sounds that have shaped him. The mix he has prepared for us is a sort of version of all the artist's inspirations taken to the weirdest and most experimental, and as he says, is another good disconnect from the screen overload. Escape with it. I really enjoyed doing something different than a club mix. It is always in the back of my desires but rarely comes to fruition. Tracklist: 0.

This is: Age changes what you care about, published by Dentin on October 16, 2022 on LessWrong. [Possible trigger warning for discussion of mortality.] I've been on LessWrong for a very long time. My first exposure to the power of AI was in the mid 1980's, and I was easily at "shock level 4" at the turn of the millennium thanks to various pieces of fiction, newsgroups, and discussion boards. (If you're curious, "The metamorphosis of prime intellect", "Autonomy", and "A fire upon the deep" all had large impact on me.) My current best guess is that there's a double-digit percentage chance the human race (uploads included) will go extinct in the next century as a result of changes due to AI. With that background in mind, existential AI risk is not my highest priority, and I am making no meaningful effort to address that risk other than sometimes posting comments here on LW. This post is an attempt to provide some insight into why, to others who might not understand. Put bluntly, I have bigger things to worry about than double digit odds of extinction in the next century due to AI, and I am a rather selfish individual. What could possibly be more important than extinction? At the moment, that would be an extremely solid 50% chance of death in the next 3-4 decades. That's not some vague guesswork based on hypothetical technological advances; it's a hundred thousand people dying per day, every day, as they have been for the last century, each death contributing data to the certainty of that number. That's two decades of watching the health care system be far from adequate, much less efficient. Consider that right now, in 2022, I am 49 years old. In 2030 I'll be 57, and there's good reason to believe that I'll be rolling 1d100 every year and hoping that I don't get unlucky. By 2040, it's 1d50, and by 2050 it's 1d25. Integrate that over the next three decades and it does not paint a pretty picture. Allow me a moment to try to convey the horror of what this feels like from the inside: every day, you wonder, "is today the day that my hardware enters catastrophic cascading failure?" Every day, it's getting out a 1d10 and rolling it five times, knowing that if they all come up 1's it's over. I have no ability to make backups of my mind state; I cannot multihost or run multiple replicas; I cannot even export any meaningful amount of data. The high reliability platform I'm currently running on needs to fail exactly once and I am permanently, forever, dead. My best backup plan is a single digit probability that I can be frozen on death and revived in the future. (Alcor provides at best only a few percent odds of recovery, but it's better than zero and it's cheap.) That's what it feels like after you've had your first few real health scares. I'd like to say that I'm noble enough, strong enough as a rationalist that I can "do the math" and multiply things out, take into account those billions of lives at risk from AI, and change my answer. But that's where the selfish aspect of my personality comes in: I turns out that I just don't care that much about those lives. I care a lot more about personally surviving the now than to have everyone survive the later. It's hard to care about the downfall of society when your stomach is empty and your throat is parched. It's hard to care about a century from now, when death is staring you in the face right now. Thanks for listening.

Die Frage, ob man Karies rückgängig machen kann, wird mir sehr häufig gestellt. Um diese korrekt zu beantworten, sollten wir erst einmal definieren, was Karies ist. Karies ist Zahnfäule - also das Loch im Zahn. So weit so gut. Dieses Wort sagt jedoch nichts darüber aus, wie tief dieses Loch ist - und genau das ist entscheidend für die richtige Antwort. Zahnärzte sprechen von Karies, wenn die Bakterien das Zahnbein (Dentin) erreicht haben. Dies bedeutet: Die Bakterien haben den Zahnschmelz - die härteste Substanz unseres Körpers überwunden. In dem Zahnbein befinden sich unzählige Kanälchen, die zum Inneren des Zahnes führen. Das Innere wird als Pulpa oder Zahnmark bezeichnet. Es enthält Blutgefäße, Nerven, Lymphe und Bindegewebe. Dies bedeutet: Sobald die Bakterien das Dentin erreicht haben, haben sie auch freie Bahn, um bis ins Zahnmark zu gelangen. Dies ist nicht mehr rückgängig zu machen. Was bedeutet: Die Karies ist nicht mehr rückgängig zu machen. Das Loch im Zahn wächst nicht mehr zu. Es kann nur repariert werden. Nun ist es jedoch so, dass manche Menschen auch von einer sogenannten Primärkaries oder Primärläsion sprechen. Vielleicht hat Dein Zahnarzt auch schon einmal zu Dir gesagt: „das müssen wir beobachten“. Diese „Primärkaries“ ist im Grunde noch keine richtige Karies. Diese Läsion wird daher nicht aufgebohrt. Es handelt sich um einen Bereich im Zahn, der entmineralisiert ist. Ein Bereich, der schon viel Säureangriff erhalten hat, ist ein ent-mineralisierter Bereich. Häufig ist er als ein etwas weißlicher Fleck am Zahn zu erkennen - ein sogenannter „white Spot“. Wenn dieser Bereich Farbstoffe eingelagert hat, kann er auch gelblich oder bräunlich verfärbt sein. Wichtig ist: Ein Bereich, der ent-mineralisiert ist, kann auch wieder vollständig mineralisieren. Dann könnte man auch sagen. „Die Karies hat sich zurück gebildet.“. Jedoch: In Wirklichkeit war es noch gar keine richtige Karies. Das kannst Du tun, um die Zähne besser zu mineralisieren: Vollwertige Ernährung. Ausreichende Flüssigkeitszufuhr (mindestens 2 Liter Wasser am Tag). Gründliche Zahnpflege mit Zahnbürste, Interdentalbürstchen und Zahnseide.. Verwende eine Zahnpasta mit vielen Mineralien wie Calcium, Magnesium, Zink. Zwei Mal täglich die Zähne putzen. Spüle den Mund aus, nachdem Du Zucker oder Obst gegessen hast. Ich wünsche viele gute Erkenntnisse in diesem Podcast.

Böse Zungen behaupten, Zahnärzte wollen ihren Patienten gar nicht verraten, wie diese eine Kariesentstehung vermeiden können. Ich bin überzeugt davon, dass dies nicht der Fall ist. Was jedoch definitiv der Fall ist: Das Vermeiden von Karies hat viel mit Selbstverantwortung zu tun. Dieser Podcast hat den Sinn und Zweck Dir zu zeigen, was Du selbst tun kannst, um Deine Gesundheit zu verbessern. Aus diesem Grund habe ich auch den Titel so gewählt. Dabei unterstützt Dich diese heutige Podcastfolge ganz besonders. Sie ist eine sehr wichtige Folge auf diesem Weg. Indem Du weißt, was Du tun kannst, um Karies zu vermeiden, bist Du einen großen Schritt weiter in Richtung allgemein körperliche Gesundheit. Die Frage, ob man Karies denn rückgängig machen kann, wurde mir schon häufig gestellt. Am Anfang habe ich sehr vehement mit „Nein, natürlich nicht“ geantwortet. Schließlich kann man ein vorhandenes Loch im Zahn nicht wieder rückgängig machen - oder doch? Da kommen wir zum Kern. Wir müssen zunächst definieren, was eine Karies ist, bzw. Ab wann wir über eine Karies sprechen. Wenn wir über eine Karies erst dann sprechen, wenn diese ein tiefes Loch in den Zahn gegraben hat, dann geht da nichts mehr mit „rückgängig machen“, aber die Karies beginnt viel früher, meist sogar Jahre früher. In dieser Zeit - also der Zeit zwischen der ersten Entmineralisation und dem Einbruch und somit dem Sichtbar werden eines tiefen Loches im Zahn - kannst Du viel tun. Zu Beginn dieser Zeit ist es tatsächlich sogar möglich, eine Karies rückgängig zu machen. Wie Du das tun kannst, erfährst Du in dieser Folge. Wichtig für Dich ist: Während dieser ersten Phase der Entmineralisation am Zahn sprechen Zahnärzte noch gar nicht von Karies. Wir sprechen von einer Entmineralisation, dann von einem White Spot, Beginn einer Karies oder Karies Stufe I. Erst wenn die Bakterien das Dentin (das Zahnbein) erreichen, sprechen wir von einer Karies und erst dann bohren wir das entstandene Loch auf. Sind die Bakterien erst im Zahnbein, ist ein Aufhalten des Defektes nicht mehr möglich. Wenn da zu spät gehandelt wird, droht eine Wurzelentzündung. Das Wissen, welches Du in dieser Folge erhältst, hilft Dir, Deine Zahngesundheit zu revolutionieren. Du brauchst keine Angst mehr vor dem nächsten Zahnarztbesuch und möglichen Kosten zu haben, weil wieder ein Neus Loch entdeckt wird. Du sparst Dir also viel Geld für teure Zahnbehandlungen. Du bekommst nicht nur gesündere Zähne, Deine allgemeine Gesundheit nimmt zu und Du fühlst Dich vitaler. Ich wünsche Dir viele gute Erkenntnisse mit dieser Folge. Wünscht Du Dir meine besondere Unterstützung beim Aufbau Deiner Gesundheit? Dann lade ich Dich zum Online Aktivprogramm ein.

This episode will continue the discussion on fiber reinforced composite and continuous fiber with researcher, academic and clinician Dr. Filip Keulemans. Composite, as you know is a mainstay, but we all know it shrinks. On average it shrinks about 1-6%. Some more, some less. And, one of the most vulnerable landmarks of the restoration is the hybrid layer. The hybrid layer, is the layer that forms when the resin monomer penetrates into the collagen fibrils of the dentin. The hybrid layer is vulnerable for a lot of reasons, but just think of the hybrid layer conceptually and you'll see why it can succumb to delamination. You're trying to get plastic to bond to a wet bodily tissue aka dentin. We've identified two challenges here - composite shrinks and we're trying to form a bond that lasts twenty years. This is where Ribbond, or a leno weave polyethylene fiber comes in. And, just for your awareness, I have no conflict of interest with Ribbond. In this episode you're going to learn a lot about fiber (aka Ribbond) from prolific researcher, scientist and clinician Filip Keulemans. Just do a pubmed search on this guy. He is leading the charge in researching fiber reinforced composites. His work has been cited by hundreds and read by thousands. He has over 20 peer reviewed articles on the topic. Throughout this discussion you may hear of two different types of fiber. There is continuous fiber and short fiber. Continuous fiber honestly looks like a thin strip of a cotton gauze and its placed in the floor of the restoration. Short fiber, on the other hand, contains small fiber particles that are dispersed throughout the composite. Short fiber is believed to make the composite much stronger. Here today to discuss this topic is Dr. Filip Keulemans. He has a background not only as a clinician but also a dental researcher. He has dozens of publications and he's even written a chapter in the textbook clinical guide to principles of fiber-reinforced composites in dentistry Find me on Instagram: @dental_digest_podcast Check out https://dentaldigestinstitute.com/
Immediate dentin sealing (IDS) is a core principle of Biomimetic dentistry (BRD) but it can be incredibly confusing. In this episode your host, Dr. Melissa Seibert will take a deep dive into what IDS is with Dr. Matt Nejad. You'll walk away with a firm understanding for what it is and how to complete it. Dr. Michael J. Morgan defined IDS best when he stated that "Immediate dentin sealing (IDS) is the application of a dentin bonding agent to freshly cut dentin when it is exposed during tooth preparation for indirect restorations (inlays/onlays, crowns). IDS is a progressive protocol designed to address the challenges of preparation, temporization, and final cementation of indirect restorative procedures, and offers several distinct advantages." (click here for full article). Dr. Nejad will be doing a webinar with the Academy of Biomimetic Dentistry that I highly recommend you attend. Click here to register. Let's connect on Instagram: @dental_digest_podcast Mizzi for Medical Professionals: Mizzi About Dr. Nejad: " Dr. Matt Nejad is an expert biomimetic and esthetic dentist practicing in Beverly Hills, CA. He is a Fellow of the Academy of Biomimetic Dentistry, the highest level of accreditation possible, and serves as a Scientific Advisor to mentor and train dentists. He provides education and training in Biomimetic Dentistry through the Nejad Institute for Biomimetic Dentistry. Dr. Nejad received his DDS degree from the Herman Ostrow School of Dentistry (University of Southern California School of Dentistry) in 2010. As a student, Dr. Nejad was mentored in a selective program run by Dr. Pascal Magne, known globally as the leading authority in esthetic dentistry and credited as the “father” of biomimetic dentistry. He finished top of this mentoring program in both the didactic testing and clinical case experience. By graduation, he completed a record amount of prosthodontic and cosmetic cases, earning a truly unique training experience. After graduating, Dr. Nejad went an unconventional route and started his own practice immediately so that he could provide Biomimetic and Esthetic dentistry exactly the way he envisioned. He was also the youngest dentist to become a member of the USC faculty, teaching alongside his mentor Dr. Magne since 2010. In 2013, he moved his practice to Beverly Hills and joined with Dr. Mark Helm and Dr. Kyle Stanley, where he currently practices full-time. Throughout his professional career, Dr. Nejad has committed substantial time and energy to advance the practice, education, and development of Biomimetic Dentistry. The Nejad Institute provides training and mentorship for dentists interested in learning Biomimetic Dentistry. Today, Dr. Nejad is considered one of the top opinion leaders in the dental industry. He is committed to the research and scientific development of adhesive and biomimetic dentistry. He consults with top companies, helping develop innovative dental materials and new products.

Dental digest is a dental podcast devoted to evidence based dentistry. A thorough understanding for advanced adhesive dentistry and biomimetic dentistry is necessary for creating composite restorations that last. In this episode, Dr. David Alleman will clear up several misconceptions related to biomimetic dentistry, advanced adhesive dentistry and operative dentistry. One of the greatest misconceptions in dentistry is that enamel obtains a better bond and stronger bond than dentin. While enamel bonding is less-technique sensitive and more straightforward, extensive literature has been published to demonstrate that dentin can obtain a stronger bond. That being said, dentin bonding is far more technique sensitive. Did you know you can earn continuing education through this dental podcast? Just visit www.dentaldigestinstitute.com to get started! About Dr. David Alleman: Dr. David S. Alleman is renowned as one of the co-founding pioneer of the of Biomimetic dental movement and his contribution to Biomimetic Dentistry. His study of advanced adhesive dentistry began with Dr. Ray Bertolotti. His studies continued to progress under the tutelage of the renowned Dr. John Kois. These two mentors and his passionate dedication evolved into his 10 year/10,000 hour review of the dental literature. This dedication enabled him to formulate the concepts on which advanced adhesive (Biomimetic) dentistry is based. Other mentors and pioneers he has collaborated with include Dr. Pascal Magne, Dr. Didier Dietschi, Dr. Gary Unterbrink, and Dr. Geoff Knight. He formerly partnered with Dr. Simone Deliperi from Sardinia, Italy to pass these techniques on to other motivated dentists.

Hello Again!!I can’t believe I’m into my 7th episode already. As you are aware, we’re running a Health series. In my last interview, we heard a lot about Good eating. This week, we’ll hear and learn a lot more on how and why our teeth are so important to us. Dr Shwetha G, a Paediatric Dentist explains sooo many important questions like why we need to use age appropriate tooth paste and brush, why we get tooth aches, why some of us have too many teeth and so much more!I hope, you enjoy listening…
A hipersensibilidade dentinária é uma das consequências das lesões cervicais não cariosas. Danos no esmalte do dente podem expor a dentina, que possui terminações nervosas e, em contato com baixas ou altas temperaturas, disparam sinais de dor aguda intensa. Por isso, há a sensação de dor ao tomar sorvete, consumir alimentos quentes ou ácidos. Segundo a professora Linda Wang, da área de Dentística da Faculdade de Odontologia da USP em Bauru, as consequências da perda do esmalte do dente e da dentina são variáveis e dependem de fatores como idade, comportamento do paciente e grupos dentários que foram comprometidos. Adverte que a perda do tecido que protege o dente pode causar comprometimentos funcionais e facilitar o acúmulo de biofilme, levando à necessidade de restauração. O afastamento da gengiva, que pode expor o tecido interno, é comumente causado por escovação exagerada e também causa sensibilidade. Nesse caso, o tratamento é feito com agentes que possam reduzir a sensação de dor. Além disso, no caso de perdas dentárias significativas e perceptíveis, é indicada a restauração. “Se houver uma perda significativa que atinja mais o tecido gengival e se houver o envolvimento de tecido ósseo, pode haver necessidade de cirurgia, porém é mais difícil de acontecer.” Momento Odontologia Produção e Apresentação: Rosemeire Talamone Co-Produção: Alexandra Mussolino de Queiroz (FORP), Letícia Acquaviva (FO), Paula Marques e Tiago Rodella (FOB) Edição Sonora: Gabriel Soares Edição Geral: Cinderela Caldeira E-mail: ouvinte@usp.br Horário: segunda-feira, às 8h05 Você pode sintonizar a Rádio USP em São Paulo FM 107,9; ou Ribeirão Preto FM 107.9, ou pela internet em www.jornal.usp.br ou pelo aplicativo no celular para Android e iOS Veja todos os episódios do Momento Odontologia .
Dr. Amy Creech-Gionis is popping in on the Dental Slang Podcast today all the way from Florida. She’s bounced around different kinds of dental offices during her career in Tampa and has pretty much seen it all. She started in a small downtown office and worked her way through DSOs and family practices to get to where she is today. She has a good sense of what she likes to do, what she doesn’t like to do, and how it’s all influencing the future she’s building for herself in the dental industry. Amy wants what’s best for all of us practicing dentists. And for her, what’s best means becoming proficient in as many aspects of dental care as we can to give our patients the best care possible. If you couldn’t tell, Amy really loves to learn. Learning as much as she can about dentistry helps her adapt to all the changes coming to the industry. It’s important to be flexible right now, and Amy discusses a few of the ways she is flexible and how the rest of us can stay ahead of the game. The old ways of dentistry are fading. Way back when, dentists were allowed to complain about change and avoid it for as long as possible. That doesn’t work these days. If dentists want to stand out from the crowd, they must show what value they bring to the table. Staying up to date with new dental technology and investing time and energy into learning new techniques, new procedures, and even investing in new tools will show patients you’re a dentist who knows what you’re doing. Amy shares a few of her own learning experiences and discusses the different ways mentors have influenced not only her dental skills but how she runs her business. Mentors taught Amy how to look ahead, and now she’s poised to take on the modern changes coming down the pipe. She has her finger on the pulse, and she’s taking us all on a ride toward what the future of dentistry could be. If you’re curious about what’s in store for our industry, tune in now to hear Amy’s expectations for the future of private practice, the new tools coming from Berman Instruments, and the new slang words she uses for some of our most tried-and-true dental procedures. In This Episode You Will Learn Why we shouldn’t be afraid of any changes coming to dentistry 7:30 When Amy found her first mentor 12:30 The different ways you can stand out as a private practitioner 16:47 The new things Berman Instruments is offering now 23:39 The best way (with slang!) to explain dentin hypersensitivity 26:54 The top slang terms Amy is using in her dental office 28:20 Some Questions We Discuss What inspired Amy to open and run multiple dental practices? 2:55 How important are mentors to Amy’s career? 11:30 What does Amy mean when she says “I never stand still”? 15:00 What are Amy and Berman Instruments working on together? 18:30 What slang is Amy using in her dental offices to help kids? 25:58 Resources: Visit our website: www.DentalSlang.com Connect with us on Facebook: Dental Slang Amy’s Mentor: Tony Feck & Sunrise Dental Solutions Cassettes from Berman Instruments

Ziel der Studie war es, die Reparaturfähigkeit der siloranbasierenden Kompositen und deren Kombinierbarkeit mit methacrylatbasierenden Kompositen zu Reparaturzwecken mittels Scherversuch zu untersuchen. Im ersten Teil der Studie wurden Proben aus siloranbasierendem Komposit und methacrylatbasierendem Komposit polymerisiert, teils gealtert durch Lagerung in Aqua dest. bei 37°C für eine Woche oder für einen Monat inklusive Thermowechselbad (5000 Zyklen zwische 5° und 55°C), teils ohne Alterung repariert. Die Proben wurden vor der Reparatur angeraut (Silikonkarbidpapier), angeätzt (37% Phosphorsäure), gründlich mit Wasser gespült und getrocknet. Das Adhäsiv (Heliobond oder Silorane System Adhesive Bond) wurde aufgetragen und polymerisiert, dann wurde die Reparaturfüllung (siloranbasierendes Komposit oder methacrylatbasierendes Komposit) aufgetragen. Die Reparaturen wurden wieder teils der Alterungsprozedur unterzogen. In Teil zwei wurden die Füllungsproben (siloranbasierendes Komposit und metacrylatbasierendes Komposit) für eine Woche in Aqua dest. bei 37°C gelagert und vor der Reparatur wieder wie in Teil eins angeraut und gereinigt. Als Haftvermittler wurden verschiedene Materialien getestet, darunter ein experimentelles siloranbasierendes fließfähiges Komposit, zwei metacrylatbasierende fließfähige Komposite, die beiden auf Methacrylat basierenden Adhäsive Silorane System Adhesive Bond und Heliobond, ein Silan in Kombination mit einem Adhäsiv und ein Reparaturset für methacrylatbasierendes Komposit. Als Reparaturfüllung wurde siloranbasierendes Komposit und methacrylatbasierendes Komposit benutzt. Die reparierten Proben wurden wiederum für eine Woche gelagert und dann im Scherversuch bis zum Bruch belastet. Die Reparaturen von siloranbasierendem Komposit mit demselben Material unter Anwendung eines siloranbasierenden fließfähigen Komposits resultierten in einer sehr guten Haftfestigkeit, vergleichbar mit der Haftfestigkeit von Reparaturen mit methacrylatbasierendem Komposit und methacrylatbasierendem fließfähigem Komposit und der Haftfestigkeit von methacrylatbasierendem Komposit an Dentin. Die Reparatur von siloranbasierendem Komposit mit methacrylatbasierendem Komposit unter Applikation eines Silans und eines Adhäsivs zeigt Haftfestigkeitwerte, die ebenfalls statistisch nicht signifikant geringer waren als die Werte der Reparaturen mit methacrylatbasierendem Komposit und methacrylatbasierendem fließfähigem Komposit, welche als Referenz dienten. Die Kombination von siloranbasierendem Komposit mit methacrylatbasierendem fließfähigem Komposit oder Phosphat-Methacrylat-Adhäsiv zur Reparatur mit methacrylatbasierendem Komposit führt zu Scherhaftfestigkeit, die sich statistisch nicht signifikant unterscheidet von der Haftfestigkeit von methacrylatbasierendem Komposit an Dentin. Die Reparaturhaftfestigkeit von siloranbasierendem Komposit mit siloranbasierendem fließfähigem Komposit zu methacrylatbasierendem Komposit erweist sich als sehr gering, gefolgt von siloranbasierendem Komposit mit methacrylatbasierendem Adhäsiv an methacrylatbasierendem Komposit. Beide unterscheiden sich signifikant von der Methacrylat- Kontrollgruppe M+M+TF (Methacrylat+Methacrylat+TetricEvoFlow). Die Reparaturhaftfestigkeit der Proben steigt mit der Alterung des Verbunds und verringert sich mit Alterung der Füllungsoberfläche. Es kann geschlussfolgert werden, dass siloranbasierendes Komposit mit gängigen, für die Reparatur methacrylatbasierender Komposite üblichen Methoden repariert werden kann. Ebenso können siloranbasierende Komposite für Reparaturzwecke mit methacrylatbasierendem Komposit kombiniert werden. Hierfür sollte um zuverlässige Resultate zu erzielen ein Silan vor der Applikation eines Adhäsivs benutzt werden. Ein siloranbasierendes fließfähiges Komposit sollte ausschliesslich zur Reparatur von siloranbasierendem Komposit mit siloranbasierendem Komposit verwendet werden, hierfür können gute Haftwerte erzielt werden. Reparierte Füllungen sollten in den ersten Stunden nach der Reparatur wenig belastet werden.

Ziel meine Arbeit war drei Methoden (Carisolv, Smartprep und Biosolv) zu vergleichen und zu überprüfen, ob es möglich ist, einen belastungsstabilen Verbund zu der so behandelten Dentinoberfläche zu etablieren. Für die Untersuchungen wurden extrahierte Zähne mit natürlicher Karies verwendet. Hier wurde entwickelt eine Methode, eine Kavität für unterschiedliche Behandlungsmethoden verwenden zu können. Die Zähne wurden in 200 µm dicke Scheiben geschnitten. Auf diese Weise wurden bis zu 10 Schnitte pro Zahn gewonnen. Die Zahnschnitte wurden stabilisiert mit Objektträgern und behandelt die Karies mit den unterschiedlichen Methoden. Das treffende Problem war eine Methode zu finden, den therapeutischen Endpunkt zu bestimmen, ohne auf die Härte der Oberfläche zurückzugreifen. Dafür wurde die Autofluoreszenz verwendet. Hier konnte mit Hilfe eines Stereo-Mikroskopes mit Fluoreszenzaufsatz die Restdicke des Zahndefektes bei zwei unterschiedlichen Wellenlängen bestimmen (FITC, TexasRED). Es wurde weiterer Untersuchungen durchgeführt (Mikrohärte, Mikrozugversuch und Rasterelektronenmikroskopie). Es wurde folgende Ergebnisse erreicht. Mithilfe der Fluoreszenzmessung konnte belegt werden, dass die neuen selbstlimitierenden Kariestherapieansätze bis zu 0.9 mm Zahnhartsubstanz belassen, die anhand von Fluorophoreinlagerungen als kariöse änderte betrachtet werden muss. Es wurde in die Untersuchung kein Vergleich zu rotierenden Stahlinstrumenten („Rosenbohrer“) aufgenommen, da Stahlinstrumente beliebig weit in gesundes Dentin schneiden können und man auf diese Weise primär den Behandlereinfluss untersucht hätte. Im Vergleich zu gesundem Dentin betrug die Härte direkt unter der Defektoberfläche zwischen 40 und 60%, was einen indirekten Beweis für substanzschonendes Vorgehen darstellt. Anhand der Mikrozugversuchsergebnisse kann man feststellen, dass die selbstlimitierende Kariestherapie mit spezifischer (Enzyme) und unspezifischer Kollagenspaltung (Natriumhypochlorit) geringere Haftwerte als gesundes Dentin aufweisen. Zu dem Produkt Carisolv liegen jedoch zahlreiche klinische Studien vor, bei denen die Dentinhaftung klinisch ausreichend war. Aufgrund dieser Daten kann man ableiten, dass auch für Biosolv eine hohe Wahrscheinlichkeit besteht, klinisch erfolgreich eingesetzt werden zu können. Die Ergebnisse waren für das Konzept der selbstlimitierenden Kariestherapie insgesamt positiv. Die Ergebnisse haben aber auch gezeigt, dass die konventionelle Bestimmung des therapeutischen Endpunktes mithilfe der zahnärztlichen Sonde bei diesem Verfahren nicht mehr möglich sein wird. Bevor die selbstlimitierende Kariestherapie Einzug in die Praxis finden wird muss somit das Problem der Kontrolle gelöst werden, ob ausreichende Beseitigung des infizierten Gewebes vorliegt.

Die Prophylaxe gewinnt nicht zuletzt auch angesichts des notwendigen finanziellen und gesellschaftlichen Sparpotentials immer stärker an Bedeutung; nicht zu Unrecht, da schließlich die meisten kariösen und parodontalen Läsionen durch rechtzeitige, fachgerecht und regelmäßig durchgeführte Prophylaxemaßnahmen in ihrer Entstehung vermieden werden könnten, so auch gesundheitliches Wohlbefinden fördernd. Das nach wie vor verbreitetste und am häufigsten angewandte „Prophylaxe-Werkzeug“ ist zweifellos die Handzahnbürste. Die vorliegende Untersuchung setzte sich zum Ziel, Unterschiede bezüglich der Dentinabrasivität zwischen verschiedenen aktuellen Handzahnbürsten mit hohem Marktdurchsatz zu ermitteln. Wie sich herausstellte, erwiesen sich die ausgewählten modernen Handzahnbürsten mit ebensolchem Bürstenkopfdesign ausnahmslos als signifikant weniger abrasiv im Vergleich zu der Referenzzahnbürste, der „ADA Control“. Die ADA Control - Zahnbürste verfügt dabei über ein einfaches Design mit geraden Borsten und planem Borstenfeld. Bereits dieses Ergebnis zeigt, eine wie rasante Entwicklung die Handzahnbürsten in den letzten Jahren genommen haben. Nicht nur das Aussehen hat dabei eine spürbare Verbesserung erfahren und sich dem Zeitgeschmack angepaßt, sondern auch die Eigenschaften wurden offensichtlich (hier die Abrasivität) deutlich verbessert. Im gesamten Testfeld zeigten drei Zahnbürsten auffallend günstige Eigenschaften in Bezug auf den Dentinverschleiß. Die „Dr. Best Brillant sensitive“, die „Oral B Advantage Plus“ und die „Dr. Best X-Sensorkopf sensitive“ zeigten die geringsten Dentinabrasionstiefen. Das Ergebnis läßt den Schluß zu, daß diese Bürsten Patienten mit parodontal vorgeschädigtem Gebiß besonders zu empfehlen sind. Gegen diese Empfehlung ist aus Sicht der Abrasionswirkung auch gewiß nichts einzuwenden, Aussagen über die Reinigungswirkung lassen sich daraus jedoch nicht ableiten. Es ist durchaus denkbar (aber keinesfalls sicher, bewegen wir uns mit folgender Schlußfolgerung doch im spekulativen Raum), daß die Bürsten mit der geringsten abrasiven Wirkung nur eine unterdurchschnittliche Reinigungswirkung zeigen. Hier liegt ein Schwachpunkt der Ergebnisse. Um zuverlässige Empfehlungen aussprechen zu können, sollte zukünftig parallel zum Verschleiß an der Zahnoberfläche auch die Reinigungswirkung getestet werden. Schließlich ist in der Reinigung der eigentliche Zweck der Handzahnbürste zu sehen! Ein weiteres Anliegen dieser Untersuchung war es, eine validierbare und zuverlässige Methode zur Testung von Zahnbürsten zu entwickeln. Um die Leistungsfähigkeit des Versuchsaufbaues zu verbessern, mußten exemplarisch zahlreiche Modifikationen an der „Zahnputz-Maschine“ vorgenommen werden. Es wurden beispielsweise neue Halterungen für die Handzahnbürsten entworfen, da die neuen Bürsten über teilweise sehr dicke, ergonomisch gestaltete Handgriffe verfügen. Die alten Halter waren für obige Studie wertlos. Ebenso mußten die Eichgewichte am Putzarm neu hergestellt und in ihrer Bauform geändert werden, um unseren Ansprüchen gerecht zu werden. Die Abrasiv-Slurry-Bäder wurden modifiziert, um einen reibungslosen Versuchsablauf zu gewährleisten. Auch Adapter, die sicherstellen, daß die Zahnbürsten während des gesamten Versuches in der vollen Länge des Bürstenkopfes aufliegen, wurden erdacht und hergestellt. Selbst die Matrize zur Probeneinbettung war zu ändern, die Schlitzfräsung wurde von 14mm auf Maximallänge von ca. 20mm vergrößert, um den Einbau größerer Proben zu ermöglichen, anderenfalls hätten zur Auswertung keine ungeputzten Dentinareale als Referenzflächen mehr genutzt werden können. Da sich die Matrize als tauglich erwiesen hat, sollte eine weitere Matrizenvariante aus dauerhaftem Stahl hergestellt werden und die mechanisch anfällige Variante aus Aluminium ersetzen. Im Rückblick sei auch kritisch vermerkt, daß sich der Nachschub an extrahierten menschlichen Zähnen zur Dentinprobengewinnung problematisch darstellt, herrscht doch oft Mangel an geeigneten Zähnen. Zudem lassen sich Störfaktoren von außen oder Lagerungsfehler nur schwer beeinflussen oder erkennen, da man notwendigerweise auf viele verschiedene Quellen zurückgreifen muß. Beispielsweise wurden stark gebleicht aussehende Zähne nicht zur Probengewinnung herangezogen, um Fehler zu vermeiden. Vermutlich wurden diese Zähne zu irgendeinem Zeitpunkt nicht in physiologischer Kochsalzlösung, sondern in Wasserstoffperoxid gelagert. Trotz Rückfragen war nicht verifizierbar, ob es tatsächlich zu solchen Lagerungsfehlern gekommen war. Obgleich die Verwendung von humanem Dentin sehr realistische Ergebnisse erwarten läßt, stellt sich jedoch die Frage, ob interindividuelle Unterschiede in der Dentinfestigkeit nicht zufällige Fehler der Ergebnisse bedingen. Bei bovinem Dentin hingegen bestehen kaum Nachschubprobleme. Außerdem lassen sich Proben in nahezu beliebiger Größe wählen und verändern. Nicht zuletzt ist es möglich, aus einem Rinderzahn, sogar aus ein und derselben Dentinschicht mehrere Dentinproben zu gewinnen, die in ihren Eigenschaften geradezu identisch sind. Ein weiterer Vorteil bovinen Dentins ist die wesentlich geringere Infektionsgefahr für den Experimentator im Gegensatz zu menschlichem Dentin, sieht man von der Bovinen Spongoencephalopathie (BSE) ab. Die Gleichwertigkeit bovinen Dentins im Vergleich zu humanem Dentin beim Einsatz in Abrasionsversuchen ist inzwischen wissenschaftlich gesichert (Imfeld, 2001). Daher sollte in zukünftigen Untersuchungen vorrangig bovines Dentin als Probenmaterial eingesetzt werden. Die vorliegenden Ergebnisse eröffnen insgesamt die Möglichkeit zu weite-ren gezielten Untersuchungen, von Zahnbürsten-Vergleichen bezüglich Abrasivität und Reinigungswirkung sowie zu Studien mit Blick auf weitere Wirkmechanismen und Interdependenzen von Abrasivität und Reinigungswirkung.

Das Ziel dieser In-vitro-Untersuchung war es die Randqualität von lichthärtenden kompositbasierten Füllungsmaterialien in Klasse-II-MOD Füllungen im approximalem Bereich zu überprüfen. In 80 extrahierten, menschlichen Molaren wurden standardisierte MOD-Inlay- Kavitäten präpariert. Bei einer approximalen Extension lag der zervikale Präparationsrand 1mm koronal der Schmelz-Zement-Grenze (SZG) und bei der anderen approximalen Extension 1mm apikal der SZG. Die Probenzähne wurden randomisiert in 10 Gruppen verteilt. In den Gruppen APB842, AKJ842, BPB842, BKJ842 wurde die präparierte Zahnoberfläche im Sinne der Total-etch-Technik vorbehandelt und anschließend wurde ein azetonbasierter Einkomponentenhaftvermittler (Prime & Bond NT oder KJ7-101-07) appliziert. Nach der Polymerisation erfolgte das Erstellen der Restaurationen aus ormocerbasierten Kompositmaterialien (experimentelles Material A und B) mittels konventioneller Verarbeitungstechnik. In den Gruppen QX812, QX814, QX524 und QFX814 wurde ein selbstkonditionierender Haftvermittler (XenoIII) auf die präparierte Zahnoberfläche aufgetragen. Der Lichtpolymerisation des Haftvermittlers folgte das Anfertigen der Restaurationen aus dem Material Quixfil. Das konventionelle Verarbeitungskonzept wurde nach den Angaben des Herstellers modifiziert. Die Polymerisationszeit wurde verkürzt und in den Gruppen QX814, QX524 und QFX814 wurde im dentinbegrenztem Kasten eine 4 mm Schicht appliziert. In der Gruppe QFX814 wurde ein Liner aus fließfähigem Komposit benutzt. Als Referenzgruppen wurden Restaurationen aus Material Tetric Ceram mit Syntac classic (TSC842) und aus Material Surefil mit Prime&Bond NT (SPB844) herangezogen. Nach dem Ausarbeiten und Politur der angefertigten Restaurationen wurden die Proben einer künstlichen Alterung unterzogen (Thermowechselbad 5/55°C, 2000 Zyklen, Kausimulator – okklusale Belastung 50 N, 50 000 Zyklen). Bei der morphologischen Untersuchung wurden Epoxyharzreplika von beiden approximalen Seiten einer quantitativen Randspaltanalyse im Rasterelektronenmikroskop bei 200-facher Vergrößerung unterzogen. Bei dem Farbpenetrationstest wurden die Probenzähne in Methylenblaulösung eingetaucht (5%, 15 Min.), geschnitten und auf die Tiefe der Farbpenetration untersucht. Statistische Analyse der Ergebnisse (Kruskal-Wallis H-test, Mann-Whitney U-test) zeigte signifikante Unterschiede zwischen den untersuchten Gruppen. Der adhäsive Verbund zwischen Komposit und Dentin war anfälliger für das Auftreten von Randspalten als der Verbund zum Zahnschmelz. Im Dentin variierte der prozentuale Anteil an perfektem Rand zwischen 87,9% (BKJ842) und 56,9% (SPB842), im Schmelz zwischen 97,2% (TSC842) und 77,4% (SPB842). In der Gruppe BKJ842 konnte teilweise signifikant bessere Randqualität erreicht werden als in der Gruppe BPB842. Die Ergebnisse der Gruppen APB842, AKJ842, BPB842, BKJ842 waren mit der Referenzgruppe TCS842 vergleichbar. In den Gruppen QX812, QX814, QX524 und QFX814 hat sich das variieren der Lichtpolymerisation und der Schichtstärke auf die Qualität der marginalen Adaptation nicht signifikant ausgewirkt. Mit einem Liner aus fließfähigem Komposit wurde die Randdichtigkeit dentinbegrenzter Füllungsränder erhöht. Die Randqualität der Restaurationen aus Material Quixfil war vor allem in der Randdichtigkeit (außer QFX814) mit der Referenzgruppe SPB844 vergleichbar.

Ziel dieser Arbeit war es, die existierende Infrastruktur und Messmethodik für die Beurteilung von Zahnrestaurationsmaterialien zu verbessern und zu erweitern, mit der Intention eine komplexe Materialcharakterisierung unter simulierten klinischen Bedingungen durchzuführen, die eine Interpretation des Materialverhaltens, sowie die Optimierung der Werkstoffe erlauben soll. Für die Konkretisierung der Messverfahren wurden in dieser Arbeit, aus einer in den letzten drei Jahren angelegten Materialdatenbank, acht Zahnrestaurationsmaterialien ausgewählt. Hierfür wurden sowohl physikalische Materialeigenschaften (Festigkeit und E-Modul im Biege-, Druck und diametralen Zugversuch, Bruchzähigkeit, mechanische Eigenschaften gemessen in einem Univer-salhärteversuch, Kriechverhalten, Härte, Polymerisationsschrumpfung) als auch der Einfluss der Polymerisationsquelle und Alterung durch Wasserlagerung und der Verbund zwischen Restaurationsmaterial und Zahnhartsubstanz, präsentiert. Als neue Untersuchungsmethoden wurden die indirekte Beurteilung der Polymerisationsgüte und Alterung, die Bestimmung der mechanischen Eigenschaften im Universalhärteversuch sowie ein Mikrozug-Prüfverfahren für die Beurteilung der Haftfestigkeit zwischen Zahnhartsubstanz und Restauration evaluiert. Korreliert mit Messungen der Polymerisationsschrumpfung, erlauben die neuen Methoden eine komplexe Charakterisierung der gesamten Restauration. Für die Abhängigkeit der Härte von der Belichtungsart und Alterung kann zusammenfassend abgeleitet werden, dass die 80% Reduktion der Vickershärte durch die Polymerisation mit LED-Lampen in den Programmen, die entweder eine geringere Intensität oder einen langsamen Anstieg der Lichtintensität aufweisen, in eine zunehmende Tiefe erreicht wird. Die Halogenlampen und eine schnelle Polymerisation schnitten entscheidend schlechter ab. Hingegen wurde die höchste Vickershärte mit der Halogenlampe und den Pulse-Programm der LED-Lampe GC erreicht. Die Polymerisation mit der Plasmalampe und den Lichtofen, sowie mit der niedrig energe-tischen LED Lampe Freelight 1, verursachten schlechtere Ergebnisse. Weiterhin zeigte sich, dass, mit Ausnahme des Pulse Programms der Lampe GC, die Lichtdosis eine entscheidende Rolle für die Qualität der Polymerisation spielt. Die Polymerisation mit der Lampe GC im Fast Cure Programm wird durch die unzureichende Härte und Dicke der polymerisierbaren Schicht nicht empfohlen. Für die Polymerisation mit der Plasmalampe Easy Cure wird eine längere Belichtungszeit empfohlen, da nach 6 s der 80%-Härtewert schon in einer Tiefe von 1,7 mm erreicht wurde. Für eine Reduktion der Belichtungszeit (12 s) bei gleichzeitiger hoher Härte und geringer Polymerisationsschrumpfung erwies sich die Lampe GC im Pulse-Programm als sehr effektiv. Weiterhin ist zu beachten, dass die geringeren Polymerisationsspannungen durch die LED-Lampen erreicht wurden, während die Plasma- und die Halogenlampe zwei bis drei mal höheren Spannungen verursachten. In der Studie der Haftfestigkeit an Dentin, zeigten alle Materialien eine auszureichende Polymerisation in den tiefen Klasse 1 Kavitäten. Die Härte an der Grenze zum Dentin ist wesentlich höher als der 80 % Wert der maximalen Härte und korreliert gut mit der Polymerisationsspannung. Eine hohe Polymerisationsspannung und ein hoher E-Modul (bzw. Vickershärte) wirkten sich negativ auf die Haftfestigkeit aus. Ein niedriger E-Modul bewirkte nur bedingt eine hohe Haftfestigkeit, jedoch einen reduzierten Verlust bei der Herstellung der Proben für den Mikrozugversuch. Bei einer ausreichenden Polymerisation an der Grenze zum Dentin, zeigten die getesteten Materialien eine gute Korrelation der Polymerisationsspannung mit der Haftfestigkeit. Für alle acht dargestellten Hybrid- und mikrogefüllten Kompositen wurden die Anforderungen der ISO 4049 und der American Dental Association Specifications erfüllt. Bezogen lediglich auf die Monomermatrixzusammensetzung, wirkte sich die Modifikation der Matrix durch Zugabe von UDMA auch in dieser Studie positiv auf die Biegefestigkeit aus. Außerdem zeigte die Weibullanalyse auch hohe Weibullparameter für diese Materialien, was auf eine gute Zuverlässigkeit zurückschließen läst. Die Schlussfolgerung der Asmussen Studie (1998) nach der auch die diametrale Zugfestigkeit mit dem Anteil an UDMA im Monomergemisch signifikant steigt, konnte in dieser Studie jedoch nur partiell bewiesen werden, wohingegen die Annahme, dass der E-Modul mit dem UDMA Gehalt sinkt, bestätigt wurde. Eine nichtparametrische Korrelationsanalyse der Festigkeiten, gemessen in den drei Belastungsarten ergab, dass zwischen der Biege- und Druckfestigkeit keine Korrelation existiert, die Biege- und diametrale Zugfestigkeit korrelieren nur schwach miteinander. Zwischen Druckfestigkeit und diametraler Zugfestigkeit ist jedoch die Korrelation auf dem Niveau von 0,01 zweiseitig signifikant. So kann zwischen Zug-, Biege- und Druckfestigkeit keine eindeuti-ge Abhängigkeit festgestellt werden. Die E-Moduli gemessen in allen vier Belastungsarten korrelie-ren gut miteinander.
