In the following video conversation, a panel of experts, including Drs. Howard Strassler, Joe Oxman, and Fred Rueggeberg, spoke with Dr. John O’Keefe, Director of Knowledge Networks at CDA, about THE key factors to consider when buying a new curing light. Panel Discussion Highlights All lights are not created equally and affect the quality of cure of composite restorations. Here’s what you need to know. Access and Ergonomics Light tips should access all aspects of the tooth’s surface easily and still emit light at right angles to the restoration’s surface. The light should also be easy to use in all patients (children and adults) ...Read More »
This summary is based on the article published in Endodontic Topics: Bioceramic materials in endodontics (May 2015) Zhejun Wang Courtesy of Wiley Publishing, you can access the full-text article for the next 3 months (PDF) Context During the past two decades, a number of major advances have been made in the field of bioactive ceramics used for endodontic treatment. Bioceramic materials, with their biocompatible nature and excellent physico-chemical properties, are widely used in endodontic applications. They can function as cements, root repair materials, root canal sealers and filling materials, which have the advantages of enhanced biocompatibility, potential increased root ...Read More »

All-ceramic or metal-ceramic tooth-supported fixed dental prostheses (FDPs)? A systematic review of the survival and complication rates
This summary is based on the article published in Dental Materials: All-ceramic or metal-ceramic tooth-supported fixed dental prostheses (FDPs)? A systematic review of the survival and complication rates. Part I: Single crowns (SCs) (June 2015) Irena Sailer, Nikolay Alexandrovich Makarov, Daniel Stefan Thoma, Marcel Zwahlen, Bjarni Elvar Pjetursson Context All-ceramic fixed dental prostheses (FDPs) are considered an established treatment alternative to metal-ceramic FDPs in daily clinical practice. The main reason to use of the all ceramics instead of metal-ceramics is based on more favorable esthetics 3. All-ceramic materials mimic very naturally the optical properties of teeth. Another more recent factor ...Read More »
This summary is based on the article published in Dental Materials: Bonding to oxide ceramics—Laboratory testing versus clinical outcome (January 2015) Matthias Kern Context A large number of articles dealing with bonding to zirconia and other oxide ceramics suggests that bonding to these ceramics would be an unsolved problem in dentistry. Most original laboratory research reports on bonding to zirconia ceramics start in their introduction with a statement pointing more or less out that achieving a reliable and predictable bond to this ceramic would be a major problem in dentistry or at least a limitation when restorations with limited or no ...Read More »
Can a patient react against composite resin fillings when diagnosed with a contact allergy to epoxy?
This post is based on a Q&A published on the Nordic Institute of Dental Materials website Can a patient react against composite resin fillings when he or she has been diagnosed with a contact allergy to epoxy? Should existing composite fillings be removed, and placement of new fillings avoided? Could resin-based luting cements pose a risk of allergy? The potential cross-reaction between BIS-GMA − a commonly used constituent of many composite resins − has been a matter of concern. However, an association has not been established. BIS-GMA has chemical similarities with epoxy, but contains an acrylic moiety, which is ...Read More »
Which technique(s) should we use to fill a Class II proximal box? Is there a difference in the long term margin integrity?
This question was submitted by a general dentist: I always worry that the cavosurface margins of class II preps are not fully filled when using composite resin. Is there a difference in the long-term margin integrity using the following 3 methods? Pack composite resin into the proximal box using an amalgam condenser. Place flowable resin along all cavosurface margins of the proximal box and cure it prior to packing composite. Place flowable resin on the cavosurface margins and then insert composite on top of the uncured flowable. Dr. John Burgess and Dr Suham Alexander provided this initial response. Dr. John ...Read More »
Context In February 2009, the Governing Council of the United Nations Environmental Programme (UNEP) agreed on the need to develop a global legally binding instrument, or treaty, on mercury. It tasked governments to negotiate through an Intergovernmental Negotiating Committee (INC) on Mercury, which met five times beginning in June 2010 and concluding in January 2013. The resulting international instrument is called the Minamata Convention on Mercury. Opened for signature in October 2013, it provides controls and reductions across a range of products, processes and industries where mercury is used, released or emitted. The Convention’s provisions for dental amalgam—a mercury-added product containing 50% mercury—make ...Read More »
