What’s New in the World of Biomaterials for Craniofacial Bone Regeneration?

I had the pleasure to meet Dr. Greeshma Thrivikraman, a young post-doctoral student working at the Bertassoni Lab at the Oregon Health and Science University. She coauthored a recent article that was published in the Dental Clinics of North America on biomaterials for craniofacial bone regeneration and she agreed to share with us details about the article and the latest in the world of biomaterials usage. I hope you enjoy the conversation and the information. Please share your thoughts, questions, and suggestions with us through oasisdiscussions@cda-adc.ca Until next time! Chiraz Guessaier CDA Oasis Manager Highlights Craniofacial bone regeneration has experienced ...

View from the Chairside: Why I Love Amalgam…And You Should Too!

Once again, I welcomed Dr. Paul Belzycki, dental surgeon from Toronto, to continue our series of clinical mentorship presentations. Dr. Belzycki presents a few interesting cases to show why he likes to use amalgam and why you should too. His premise follows research findings on the biochemical stability and durability of dental resin composites and is based on a clinical career that spans over close to four decades.  We hope that you enjoy the presentation and benefit from the clinical tips that he shares with you. Please share your thoughts, questions, and suggestions with us at oasisdiscussions@cda-adc.ca  Until next time! ...

JADA Article Commentary: Dental Disease Before Radiotherapy in Patients with Head & Neck Cancer

In December 2017, the Journal of the American Dental Association (JADA) published an article on guidelines for preventive dental care. In it, the authors attempted to bridge a perceived knowledge gap through the development of a clinical registry of dental outcomes in head and neck cancer patients.  Dr. Bob Wood, oral radiologist and forensic dentist at Princess Margaret Cancer Center, suggests that the article needs a careful interpretation and an appropriate contextualization of the individualized treatment provided to these patients.  I hope you find the information beneficial and you will share your thoughts, suggestions, and questions with us through oasisdiscussions@cda-adc.ca ...

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 ...

View from the Chairside: Holy “Bleep” or the Anatomy of a Misadventure

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. In this post, it is not my intention to disparage any one individual, but to emphasize a Philosophy of Treatment that should not be obscured by the new technical wizardry and materials that are nowadays available to dentists. The main messages of this case presentation evolve around ...

Practice-Based Clinical Research in Canadian Dental Practices: Dr. Edsard van Steenbergen

Dr. Edsard van Steenbergen speaks with Dr. Chiraz Guessaier about his practice-based orthodontic research which focused on biomechanics. His research results are currently published in the Angle Orthodontist and in the American Journal of Orthodontics and Dentofacial Orthopedics. Dr. van Steenbergen designed his research study with the help of two professors at the University of Connecticut and the University of Amsterdam. The actual data gathering and analysis took 4 years, followed by another 4 years of work for the publication, writing and defending the thesis. The investigation was carried out within his own clinical practice with a goal of examining ...

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 ...
