How to Correct a Transverse Posterior Crossbite with Dr. David Kennedy

Dr. David Kennedy, orthodontist, at the faculty of dentistry at UBC spoke with Dr. Chiraz Guessaier about the correction of transverse posterior crossbites. Access the PPT Presentation of this video (PDF) Highlights In patients with posterior crossbites, early treatment will frequently permanently correct the condition. A posterior crossbite with a functional shift left untreated can lead to some adaptive growth changes. Additionally, managing this condition later on is often more difficult to treat. The most common posterior crossbite is one in which there is a unilateral presentation and there is a functional shift of the mandible. This constitutes ~80-90% of ...

When Should You Refer a Case for Endodontic Treatment?

Drs. Gevik Malkhassian and Craig Bellamy, Endodontists in Toronto, spoke with Dr. John O’Keefe about when general dentists should refer patients for endodontic treatment.  Highlights While mid-treatment challenges can occur in a seemingly “straight forward” endodontic treatment, a careful pre-assessment of the tooth and one’s own skill and expertise can minimize and/or prevent some of these challenges before treatment is started. In some instances, it may be determined that an endodontic referral is in the best interest of the patient and the practitioner. Some of the questions to consider include: Do I feel comfortable completing this treatment? Have I successfully treated ...

Impact of Proton Pump Inhibitors on Implant Osseointegration

Dr. Faleh Tamimi, Assistant Professor in the Faculty of Dentistry at McGill University, spoke with Dr. Chiraz Guessaier about the research he conducted and the articles he co-authored on the impact of proton pump inhibitors on implant osseointegration. Highlights Systemic administration of omeprazole interferes with bone healing and implant osseointegration: an in vivo study on rat tibiae Proton pump inhibitors, over-the-counter drugs taken by millions of patients, diminish bone accrual. Accordingly, we hypothesized that these drugs could impair bone healing and implant osseointegration. This study investigated the effect of post-operative systemic administration of omeprazole on bone healing and implant osseointegration ...

Impact of Antihypertensive Drugs on Implant Osseointegration

Dr. Faleh Tamimi, Assistant Professor in the Faculty of Dentistry at McGill University, spoke with Dr. Chiraz Guessaier about the research he conducted and the articles he co-authored on the impact of proton pump inhibitors on implant osseointegration. Highlights Propranolol enhances bone healing and implant osseointegration in rats’ tibiae Propranolol, a non-selective b-blocker widely used to treat cardiovascular conditions, favours bone accrual. Accordingly, we hypothesized that propranolol could be useful for improving bone healing and osseointegration. This in vivo study was designed to investigate the effect of propranolol on bone healing and osseointegration in rats’ tibiae. On 24 Sprague–Dawley rats, a unicortical defect was ...
