He served as a dental officer in the Canadian Forces between 1998 and 2007. Dr. Khan began practicing dentistry in Halifax, Nova ...

Research studies showing the negative impact of tobacco products on oral health care continue to deal with the ever-evolving tobacco landscape. The increasing use of wide-ranging tobacco products calls for more research into people’s exposure to harmful ingredients found in these products. That is the subject of a recent research study that was presented at the International Association of Dental Research conference held in July in London England. The study is titled: Nicotine and Carcinogen Exposure By Tobacco Product Type And Dual-Use. And, we have invited one of the authors of the study to tell us more about its findings. ...

Tooth decay is the most prevalent chronic disease in children and adults and is caused by bacterial imbalance occurring in the mouth. A team of Illinois bioengineers set out to know more about one particular bad bacterium, Streptococcus sobrinus, that accelerates tooth decay in some people. The team, led by Dr. Paul Jensen, has successfully sequenced the complete genomes of three strains of Streptococcus sobrinus. So, I invited Dr. Paul Jensen to tell us more about his team’s work and to give us insights on the impact of this work on oral health research. Dr. Jensen is Research Assistant and ...

We hear much talk about e-cigarettes: those who believe they are a safe alternative to conventional smoking and a tool to smoking cessation; and those who voice their concerns about the negative effects of vaping on overall health. The fact is: we don’t know much about e-cigarettes because research has yet to catch up with the fast and rising uptake of these devices. In a recent article published in Vascular Medicine, a team of German researchers undertook the first-of-its kind research to study the risk of vaping on the cardiovascular system. We have invited Dr. Klaas Fransen, corresponding author to tell ...

Purpose This study investigated the ability of observers to match tooth shades visually and with a dental spectrophotometer over several sessions. Method A variety of dental professionals (dentists, dental lab technicians, assistants) were asked to ...
