Dental podcast: Welcome to DentalTalk. I'm Dr. Phil Klein. With trade shows grinding mostly to a halt for an entire year and little certainty about when they will return in full force, many manufacturers have turned to online options to connect with their customers. This includes continuing education, product videos and even web-based hands on programs. One major dental company, Ivoclar Vivadent, has done quite a lot of this, but now they're doing even more. They've invested in a 40 foot mobile trade show and taken to the North American highways to embark on an educational experience like no other.

Don Bell, the Vice President of Product Marketing in North America for Ivoclar Vivadent (https://www.ivoclarvivadent.us/), has seen a lot of products come and go. He has seen a lot of technology come and go. As labs and manufacturers enter this new era of dentistry, Don and Ivoclar has had to adapt. But in a good way. Don talks about what happened at Ivoclar during the shutdown and how they are coming back, their one-puck denture milling system called Ivotion, the e.max ZirCAD Prime, and what's next for Ivoclar. The UP 3D P5 milling maching (https://www.aurident.com/p5/) from Aurident (https://www.aurident.com/)is a 5 axis, efficient, dry mill. Great for milling zirconia, PMMA and wax. It boasts software that produces high precision and fast milling. It can mill a crown in 14 minutes and the tool life yields about 60-80 hours of quality restorations. A game changer for labs of all sizes, big and small. For under $20K, a small lab can now do their own milling instead of outsourcing and reducing their profits. Quite impressive! Give Aurident a call at 800-422-7373 or you can visit their website at aurident.com.

On this episode Evert chats with Dr. Terry Wong on a skype call all the way from Australia. They talk about all things composite. Why it might be a good idea to get out that wax carving knife again and advantages composite has over conventional indirect ceramics. Below is a short CV  “With 30-years of clinical experience and 6 successful start-up practices under his belt, Dr. Terry Wong has lectured both locally and internationally on Resin Composite. Having attended the Las Vegas Institute, studied occlusion at the Kois centre in Seattle and having been personally instructed by Dr Newton Fahl of the Fahl School of Art and Science in Aesthetic Dentistry in Brazil, Dr. Wong has travelled far and wide to perfect his composite resin technique. Dr. Wong has been conducting hands-on training workshops for Dentists on the topic of Composite Resin since 2004 and is a Key Opinion leader for major Dental companies such as 3MEspe, Ivoclar Vivadent, Coltene Whaledent, SDI and Dentsply/Sirona. Presently Dr. Wong lectures at the University of Melbourne on the topic of Aesthetic and Restorative Dentistry, as well as maintaining a dental practice in Melbourne with an emphasis on restorative dentistry.” As quoted from Dentalcoursesinternational.com.au 

CEO of Ivoclar Vivadent, Diego Gabathuler, shares his perspective on what it means to lead a customer-centric business. Diego and show host, Julia, discuss why he’s become such an ardent supporter of customer experience, how he’s moving the business from CX strategy to action and what CX professionals need to do to win over senior business leaders. If you’d like to know what drives an authentically customer-centric mindset at the highest levels of business leadership, then this episode is for you. Insights from a senior business leader Diego Gabathuler has been the CEO of the dental company Ivoclar Vivadent AG, headquartered in Schaan, Liechtenstein, since 1 July 2019. The Swiss native initially joined the company as a member of the Global Product Management in 2002. He then went on to work for Logitech and several other companies until he rejoined Ivoclar Vivadent in Schaan as Senior Director Europe West & South, Near & Middle East and Africa in 2016. Since October 2017, he has been a member of the Corporate Management. Ivoclar Vivadent is one of the world's leading manufacturers of innovative material systems for high-quality dental applications. The company has wholly owned subsidiaries in 29 countries, and it employs about 3,500 people worldwide. Diego views customer experience as a key strategic imperative for the success of any business today...and one that should be led by the CEO. It's in my title. For me CEO means Customer Experience Officer. - Diego Gabathuler CX as a differentiator Diego has taken on customer experience as one of his core strategic imperatives. He sees a customer marketplace that is increasingly complex, both for companies and for consumers. With more technology and a faster flow of information, products can also quickly become commoditized. Amid this landscape, customer experience becomes one of the few ways that businesses can stand out. These changes haven't happened overnight, and Diego highlights that as one of the challenges. Without a "big bang" push towards customer experience, it means that many companies have been too slow to respond.  Diego highlights that he sees customer experience and brand as one in the same. A brand, from his perspective, is the sum of the experiences provided by that brand. That's a progressive view on the concept of branding, and one that many CX professionals would like to be more widely used within the marketing community. Customer-centric thinking requires understanding the customer Early in our interview Diego pointed out the importance of understanding customers and integrating their perspectives into the customer journey, product innovation, and business planning. This is the foundation of customer-centric strategy. The dental industry has been largely product-led for many years, but Diego has pushed his team to actually listen to the customer, rather than relying soley on expert insights, which is often the default in his sector. That said, not all voice of customer (VOC) insights are created equal. Diego spoke about the need to unify customer experience data from 3 different sources in order to provide a robust picture of customer needs: Field research, observation and big data. Asking customers what they want might sound like the best approach, but CX teams need to pair this with user data to see what customers are actually doing. For example, the Ivoclar Vivadent team conducted research to find out where customers wanted to get their product information. Customers responded that they referenced print materials (e.g. catalogs, and brochures) but user data suggested that most were actually getting their information online. Diego chalks this up to people reflecting on their past experiences and longstanding habits, rather than recent behavior. Had the team only listened to customer feedback without pairing this with behavior observations, they might have made the wrong decisions about which touchpoints to focus on. ...

Adhäsive Füllungstherapie scheitert oft an den Folgen von Sekundärkaries. Bakterielle Infektionen nach dem Legen der Füllung führen häufig zu Pulpa-schädigungen und Füllungsverlusten. Auch während der Erstbehandlung in der Kavität verbliebene Bakterien können über den Erfolg der Restaurationen ent-scheiden. Daher ist es sinnvoll auf Karies hemmende Füllungswerkstoffe zurück zu greifen. Aufgabe der vorliegenden In-vitro-Studie war es daher zu untersuchen, ob ein antibakterielles Adhäsiv _ Clearfil Protect Bond, das ein antibakterielles Monomer MDPB (12−Methacryloyloxydodecylpyridiniumbromid) und Natriumfluorid beinhaltet, die Entstehung von Sekundärkaries im Bereich von Füllungsrandspalten inhibieren kann. Die Effektivität von Clearfil Protect Bond sollte vergleichend mit bisher genutzten und bewährten Restaurationsmateria-lien wie Fluorid freisetzendem Glasionomerzement _ Fuji IX (bekannt als Kariesprotektiv) und MDP (10-Methacrylat-oxydecyl Dehydrogenphosphat) enthaltendem Clearfil SE Bond (bekannt durch stabile und gute Haftwerte) untersucht werden. Für die Durchführung der Untersuchungen wurde eine künstliche Mundhöhle gebaut. Für die gesamte Studie wurden 24 kariesfreie menschliche Molaren verwendet. In diesen wurden Kavitäten der Black Klasse I (Ø 4 – 5 mm x T 1,8 – 2 mm) präpariert. Die Zähne wurden randomisiert in 4 Gruppen geteilt und unterschiedlich behandelt: 1. Die Proben der Gruppen OB dienten als negatives Beispiel für vermehrte Randspaltbildung, sie wurden ohne die Anwendung des Haftvermittlers mit Komposit (Tetric Ceram HB der Firma „Ivoclar Vivadent“, Schaan, Liechtenstein) gefüllt. 2.Gruppe F: Fuji IX (“GC” Europe, Leuven, Belgien) 3.Gruppe SB: Clearfil™ SE Bond (Kuraray Medical Inc., Okayama, Japan und Komposit (Tetric Ceram HB der Firma „Ivoclar Vivadent“, Schaan, Liechtenstein) 4. Gruppe PB: Clearfil™ Protect™ Bond (Kuraray Medical Inc., Okayama, Japan) und Komposit (Tetric Ceram HB der „Ivoclar Vivadent“, Schaan, Liechtenstein) Die Restaurationen wurden der thermischen Wechselbelastung (2000 Zyklen, 5 °C und 55 °C) und Kausimulation (50000 Zyklen, 5 kg Belastung) unterzogen, um Randspalten zu induzieren. Vor dem Einbringen in die künstliche Mundhöhle lagerten die gefühlten Zahnproben 4 Wochen lang in sterilem künstlichem Speichel. Die Simulation der Black Klasse II Restaurationen erfolgte durch Separation der Zähne in zwei gleich große Hälften (mesiale und distale Teile). Nach 20 Minuten langer Desinfektion in 70 % Ethanol wurden die Probekörper in die künstliche Mundhöhle eingebracht und einkeimiger streptokokkaler Plaque ausgesetzt, um sekundärkariöse Läsionen zu erzeugen. Die Studie wurde in drei Untersuchungsabschnitten mit jeweils 8 Zähnen durchgeführt. In Untersuchungsabschnitt I wurde die optimale Verweildauer der Zahnproben in künstlicher Mundhöhle für die Demineralisationsentstehung ermittelt. Diese wurde auf 8 Wochen festgesetzt. Weiterhin folgten identische Untersuchungsabschnitte II und III, die jeweils 8 Wochen lang andauerten. Durch dieses Vorgehen wurde die Aussagekraft der ermittelten Ergebnisse gesichert. Das Ausmaß der entstandenen Demineralisationen an den Kavitätenrändern wurde in einem µCT- Gerät gemessen. Die erzielten Ergebnisse ließen erkennen, dass keines der verwendeten Materialien in der Lage war die Sekundärkaries am Entstehen komplett zu hindern. Wie erwartetet, entstand in den Gruppen OB, die ohne Adhäsivsystem restauriert wurden, im Vergleich zu den anderen Gruppen (SB, PB, F) signifikant mehr Sekundärkaries. Die mit Clearfil Protect Bond behandelten polymerisierten Proben zeigten signifikant weniger ausgeprägte Sekundärkaries (bzw. Mineralverlust) in Bereichen, die direkt am Restaurationsmaterial angrenzten, als Gruppen wo Clearfil SE Bond angewendet wurde. Ab einer Entfernung von 40 µm und mehr (80 µm; 120 µm) von der Kavitätenrand konnten keine signifikanten Unterschiede zwischen diesen Materialien (PB und SB) festgestellt werden. Als kariesprotektive Materialien nehmen die Fluorid freisetzenden Glasionomerzemente eine führende Stellung ein, denn in den Gruppen der mit Fuji IX behandelten Proben entstanden signifikant geringere sekundär- und primärkariöse Läsionen als in anderen Gruppen (SB, PB, OB). Aus den Ergebnissen dieser In-vitro-Studie lässt sich ableiten, dass das MDPB Monomer auch nach der Polymerisation antibakteriell wirkt und dass es im feuchten Milieu nicht freigesetzt wird, so dass durch die Verwendung von Clearfil Protect Bond ein permanenter Schutz vor Sekundärkaries im Randspaltbereich zu erwarten ist. Daher kann für dieses Produkt eine Praxisempfehlung ausgesprochen werden. Da die zell- und pulpatoxischen Effekte, die eventuell von dem MDPB Monomer hervorgerufen werden können, in dieser Untersuchung nicht berücksichtigt wurden, muss es Ziel weiterer Studien sein, die Biokompatibilität dieses Produktes zu prüfen. Ob die in dieser In-vitro-Studie ermittelten Ergebnisse sich ohne weiteres auch in vivo übertragen lassen, bleibt den weiterführenden klinischen Langzeitstudien überlassen.

In der vorliegenden in-vitro Studie wurden die physikalischen, chemischen und biologischen Eigenschaften eines experimentellen Calciumperoxidhaltigen Sealermaterials und die von drei verschiedenen konventionellen Sealermaterialien (Apexit, Ivoclar Vivadent; AH Plus, Dentsply DeTrey; Sealapex, Kerr Sealapex) untersucht. Die statistische Auswertung der physikalischen und biologischen Eigenschaften ergab: 1. Abbindezeit. Der experimentelle calciumperoxidhaltige Sealer besitzt eine ausreichende Abbindezeit von 137,5 Minuten unter standardisierten Testbedingungen (ISO 6876). 2. Fließverhalten. Die Ergebnisse nach der ISO Methode (ISO 6876) zeigen, dass der experimentelle calciumperoxidhaltige Sealer (53,09 mm) und AH Plus (49,39 mm) eine höheres Fließverhalten haben als Sealapex (38,89 mm) und Apexit (45,45 mm). 3. Löslichkeit. Der empfohlene Löslichkeitswert für Sealer beträgt 3% (Britisches Standart BS 6934 1988). Der Löslichkeitswert des experimentellen calciumperoxidhaltigen Sealers (2,75%) entsprach dieser Vorgabe. 4. Wasseraufnahme. Zur Vermeidung einer Reinfektion des Wurzelkanals sollten Wurzelkanalsealer formstabil und porenfrei sein. Die Wasseraufnahme während eines 4 wöchigen Zeitraumes nahm in folgender Reihenfolge zu: AH Plus 0,37% (Gruppe B) < experimenteller (CaO2)-haltigen Sealer 2,13% (Gruppe D) < Sealapex 2,46% (Gruppe A) < Apexit 9,47% (Gruppe C). 5. pH-Wert. Ziel dieser Studie war es, pH-Werte des experimentellen calciumperoxidhaltigen Sealers mit denen der drei anderen konventionellen Sealer (Sealapex, Apexit und AH Plus) über einen Zeitraum von 6 Monaten zu vergleichen. Der pH-Wert des experimentellen calciumperoxidhaltigen Sealers war im Gegensatz zu den calciumhaltigen Sealer in allen Testgruppen niedriger und blieb konstant. Dies könnte einen positiven Effekt auf den biologischen Knochenanbau am Foramen apicale haben. 6. Dimensionsstabilität. Eine erfolgreiche endodontische Therapie sollte eine komplette Obturation des Wurzelkanalsystems voraussetzen. Aus diesem Grund sollten Sealer eine volumetrische Stabilität oder nur eine geringe Volumenzunahme zeigen. Der experimentelle calciumperoxidhaltige Sealer zeigte eine Expansion von 3,9% und blieb nach 2 Wochen konstant. 7. Farbstoffpenetrationstest. Die Dichte des experimentellen calciumperoxidhaltigen Sealers (1,1 mm) war mit der von AH Plus (0,97 mm) nahezu identisch. Beide Sealer zeigten erheblich bessere Ergebnisse als Sealapex (1,3 mm) und Apexit (2,35 mm). 8. Die antimikrobielle Wirkung der 7 untersuchten Sealers und temporalen Einlagen zeigte sowohl im Agardiffusionstest als auch im Keimträgerversuch an humanen Zahnpräparaten deutliche Unterschiede. 9. Agardiffusionstest. Calciumhydroxid- und calciumoxideinlagen waren gegen alle Mikroorganismen wirkungsvoll. Calciumperoxidhaltige Einlagen und calciumperoxidhaltige Sealer zeigten einen geringfügig kleineren antimikrobiellen Effekt. Der Hemmhof bei Enterococcus faecalis war am größten. Sealapex hatte ebenfalls gute antimikrobielle Wirkungen. AH Plus zeigte wenig antibiotische Effekte und war gegen Enterococcus faecalis wirkungslos. Apexit hatte auf Escherichia coli und Candida albicans keine antimikrobielle Wirkung. 10. Keimträgerversuch an humanen Zahnpräparaten. An humanen Zahnpräparaten applizierte calciumperoxidhaltige Sealer und calciumperoxidhaltige Einlagen waren gegen alle verwendete Mikroorganismen wirkungsvoll. Calciumoxid- und calciumhydroxidhaltige Einlagen und Sealapex führten zu einer Beseitigung von Escherichia coli, hatten aber auf Candida albicans, Enterococcus faecalis, Streptococcus sanguinis und Staphylococcus lentus keinen Effekt. AH Plus zeigte bei Escherichia coli und Streptococcus sanguinis antimikrobielle Eigenschaften. Apexit hatte keinen antibakteriellen Effekt. 11. Zusammenfassend waren calciumperoxidhaltige Sealer und Einlagen gegen alle geprüften Mikroorganismen wirkungsvoll. Die Materialien führten zu einer Eliminierung aller Mikroorganismen in den Dentintubuli und zeigten eine effiziente Wachstumshemmung im Agardiffusionstest. 12. Die antibakteriellen Experimente zeigen, dass der calciumperoxidhaltige Sealer und Einlage für eine Behandlung von infizierten Wurzelkanälen geeignet ist. 13. Die Verwendung von Calciumperoxid als Wurzelkanalfüllung, verglichen mit Calciumoxid und Calciumhydroxid, hatte auf die untersuchten Mikroorganismen ein größeres Wirkungsspektrum. Dabei konnten vor allem antibiotische Effekte gegen Enterococcus faecalis und Candida albicans nachgewiesen werden. 14. Vor einem möglichen klinischen Einsatz von Calciumperoxid als neue Wurzelkanalsealer und temporale Einlage müssen die toxikologischen Eigenschaften und die Bioverfügbarkeit untersucht werden. 15. Diese Studie stützt sich allein auf in-vitro-Untersuchungen. Für die Anwendung von Calciumperoxid in vivo sollten klinische Studien folgen.
