This post was prepared in collaboration with Pulpdent On an experimental basis, we have asked a limited number of companies to provide us with practical “How To” answers to clinical questions. We were prompted to conduct this experiment when dental team members told us that they visit company websites and consult company representatives for practical clinical information. We look forward to receiving your feedback on this experiment. Tuff-Temp Plus: Esthetic, Durable and Long-Lasting Provisional Material Tuff-Temp Plus is an esthetic, durable and long-lasting provisional material that can be used for single crowns or full mouth reconstructions. The material contains a ...

  The following consensus statements were developed by 53 participants from academia and industry who attended the Northern Lights Conference held at Dalhousie University, in Halifax, Nova Scotia, on November 4 & 5, 2016. Access: What should you look for in a curing light? Consensus Statements on Bulk Fill Resin Composites By Dr. Richard Price  Introduction In the context of this document, bulk fill materials are light-cured, resin-based composites that can be placed in increments of 4 mm (or in a few cases 5 mm) according to the manufacturer. It is strongly recommended that before using a product, the clinician ...

Shawn Parisien from Watersedge Dental Laboratory shares a few tips on the importance of tray selection for taking alginate impressions. Alginate impressions play an important role in dentistry on a day-to-day basis. For this reason and to ensure the accuracy of impressions, tray selection is an essential consideration. Several stock trays exist; however, some types of trays are better for polyvinylsiloxane impressions and others for alginate. Distortion and lifting of the impression material is a common issue when removing alginate impressions/trays from a patient’s mouth. To minimize both, trays used for alginate impressions should be rigid and have multiple and ...

In this short video segment, Rob Waters from Watersedge Dental Laboratory speaks to Dr. Suham Alexander about how the lab has instituted a protocol to help ensure the predictability and consistency in outcomes for dentists and their patients. When an impression is taken for crown and bridge or implant restorations, a master model is poured. There are times, however, when the restoration may seat fully and accurately on the master model but, may differ when seated in the patient’s mouth. This may be caused by distortion and the fact that master models may get worn at times with the constant ...

This post was prepared in collaboration with Bisco On an experimental basis, we have asked a limited number of companies to provide us with practical “How To” answers to clinical questions. We were prompted to conduct this experiment when dental team members told us that they visit company websites and consult company representatives for practical clinical information. We look forward to receiving your feedback on this experiment. Etching the enamel and dentin surfaces is an important step in the placement of bonded restorations. However, evidence suggests that when etching the dentin surface, acid activates a group of proteolytic enzymes known as ...

This summary is based on the article published in The Journal of Prosthetic Dentistry: Digital versus conventional impressions for fixed prosthodontics: A systematic review and meta-analysis (August 2016) Context  In the fabrication of fixed multi- or single unit dental restorations, the accuracy of marginal and internal fit are integral to the long-term success of the crowns. Discrepancies in the internal fit can adversely affect the seating of the crown as well as the marginal fit. Typically, an impression captures the restorations’ margins and their internal aspects. Nowadays, impressions can be made using conventional impression materials such as polyether or polyvinyl siloxane or ...

Dr. Steve Bayne who was a professor in the School of Dentistry, University of Michigan and distinguished speaker at the recent IADR meeting in Seoul South Korea spoke with Dr. Chiraz Guessaier. Dr. Bayne’s presentation was titled “Current Challenges for Dental Materials Research: The Street Light Effect.” Highlights Currently, there is too much product testing, with little understanding of causes and effects to properly interpret results. Although dental materials researchers do good research, their efforts could produce more significant results if: Focus was directed towards the important problems, and A more basic scientific approach was taken while using more sophisticated ...

Dr. Randy Allan will be a speaker at the upcoming CARDP meeting which will take place in Halifax in September 2016. Highlights Dr. Randy Allan speaks to Dr. Suham Alexander about his presentation at the CARDP meeting and shares two of his many cases. Randy will be speaking about the use of gold as a restorative material. Gold has traditionally been a predictable and biocompatible restorative material in dentistry but, its use has declined over the years for several reasons: • Several tooth-coloured restorative materials are available • Patient perceptions about esthetics and how gold may show in the smile line ...
