What is the Clinical Relevance of Bond Strength?

Dr. Rick Carvalho is Professor in the Department of Biomaterials at the University of British Columbia. He joined me to speak about the relevance of laboratory research on bond strength and how it translates into clinical practice. Oftentimes, the durability of adhesive restorations is estimated from laboratory bond strength testing, and there is an equivocal assumption that higher bond strength indicates longer survival in the clinic. However, there are several and significant limitations to such association that need to be understood before relevant predictions can be made. I hope the interview sheds some light on questions that you might have ...

Understanding the Genetic Mutations and Interactions that Cause Cleft Lip with or without Cleft Palate

Highlights What is IRF6 and why was it important for you to look into this gene’s activity? The IRF6 gene is arguably one of the most significant contributors to the incidence of, and susceptibility to, cleft lip / palate. It encodes a protein, called a transcription factor, that functions in the nucleus of cells to turn on other genes. It primarily functions in epithelia, particularly in the developing embryo. It is a member of a small family of proteins, called interferon regulatory factors, that also have a role in immunity. What was the underlying theory of your research and how did you ...

Look for the password to watch the presentation in the Dec 20th CDA Oasis Bulletin or email us at oasisdiscussions@cda-adc.ca to receive the password.   I was approached by Chiraz from CDA Oasis to present a case requiring extensive treatment to correct dental problems that resulted from clinical mismanagement by a previous clinician.

The main messages of this case presentation evolve around ...

View from the Chairside: Artistic Interpretation and Smile Design

Highlights In the anterior segment, as the number of guiding landmarks to determine restorative tooth anatomy decreases, the need for artistic interpretation to create new landmarks increases. In this presentation, Dr. Paul Belzycki recounts his personal clinical experience in attaining that artistic vision. In his opinion, only so much can be acquired didactically, much of it is a result of trial and error, learned by personally contouring extensive restorations in the provisional phase to ensure the achievement of a mutually agreed upon design with the patient. Once established, that design must be effectively communicated with laboratory to guide that phase ...
