The Network for Canadian Oral Health Research (NCOHR) has introduced a working paper series. The summary in this post is based on the first paper in the series. The Network for Canadian Oral Health Research (NCOHR) is committed to supporting knowledge exchange among researchers, community partners, and the public. The working paper series attempts to fulfill this commitment by providing a means to disseminate well-written, but not yet published, research. Full-text article (PDF) Internationally, health policy analysts are often surprised that Canada’s national system of health insurance (Medicare) does not include dental care. Understanding the historical reasons for its exclusion can ...Read More »

This summary is based on the article published in the Journal of Neuroscience: Drug-Evoked Synaptic Plasticity Causing Addictive Behavior (November 2013) Context The core element of the addiction process: an initially neutral stimulus becomes attractive when associated with drug consumption, and even after prolonged periods of abstinence this cue may trigger craving and cause the subject to relapse. Therefore, many researchers have argued that the secret to understanding addiction lies in the elucidation of the “memory trace” that links the cue to the compulsive drug use. The implicit underlying hypothesis is that addictive drugs generate an inappropriate learning signal that leads to the encoding of a unique trace, which, when reactivated, has ...Read More »
This summary is based on the article published in the Pediatric Dentistry Journal: The safety of sedation for overweight/obese children in the dental setting (September/October 2012) Purpose of the Study Examine childhood overweight/obesity as a risk factor for adverse events during sedation for dental procedures. Key Messages Overall, weight percentiles were higher in children who had one or more adverse events. Similarly, patients with higher body mass index (BMI) percentiles were more likely to experience adverse events. Although preliminary in nature, these findings suggest that childhood overweight/obesity may be associated with adverse events during sedation for dental procedures. In the interim, practitioners should obtain ...Read More »
This question was submitted by a general dentist: Is there a resource with current information on appropriate oral care for severely disabled and G tube-fed population? There are many position papers and guidelines indicating that this population needs care. However, I found only limited information on the actual clinical treatment provided to them and on what the treatment goals should be. These patients often present with gross calculus, limited cooperative ability for professional cleaning, and present with the risk of an aspiration pneumonia. Any attempt to clean the teeth in the office is limited at best, then the question is: what ...Read More »
This summary is based on the article published in the Dental and Medical Problems journal: Primary Failure of Tooth Eruption – Etiology, Diagnosis and Treatment (Issue 50 (3) 2013) Context Primary failure of eruption (PFE) is a rare condition that involves impeded eruption of teeth despite the lack of an identified local or general causative factor. Since molar teeth are mainly concerned, a typical clinical image presents extensive lateral open bite. A characteristic radiological feature depicts large radiolucent fields around embedded tooth germs. Research performed in recent years has provided evidence that a defect of the eruption mechanism on a genetic background is responsible for ...Read More »

Dr. Florin Amzica of the University of Montreal faculty of dentistry recently published in PLoS ONE an article on never before reported cerebral activity in people with a flat electroencephalogram (EGG). Dr. Amzica is an associate professor and the head of the laboratory on sleep neurophysiology and altered state of consciousness at the University of Montreal. His research interests include the understanding and management of dentistry-related sleep disorders. The JCDA Oasis team spoke with Dr. Amzica to find out more about his groundbreaking finding. Here are the study key points. Research highlights Brain activity extends beyond deep coma associated with ...Read More »
Diabetes and periodontal diseases: what does the consensus report of the Joint EFP/AAP Workshop on Periodontitis and Systemic Diseases say?
This is the summary of the report issued by the Joint European Federation of Periodontology and the American Academy of Periodontology Workshop on Periodontitis and Systemic Diseases: Diabetes and periodontal diseases: consensus report of the Joint EFP/AAP Workshop on Periodontitis and Systemic Diseases (April 2013) Context Diabetes and periodontitis are complex chronic diseases with an established bidirectional relationship. There is long-established evidence that hyperglycemia in diabetes is associated with adverse periodontal outcomes. However, given the ubiquity of periodontal diseases and the emerging global diabetes epidemic, the complications of which contribute to significant morbidity and premature mortality, it is timely to review ...Read More »
