I study different dental treatments for people without teeth, with the use of dental implants or dentures. As these treatments tend to be costly, one of my goals is to test more affordable ways to do them. I am also interested in testing methods to maintain oral health in people who use dentures. Most of them are elders; 21% of Canadians aged 60 years or more have no tooth, and they are more frequent in Quebec. People without teeth have difficulties chewing tough or hard foods and may prefer softer and processed foods, so tend to have a poor diet. This can put them at a higher risk for diseases, such as dementia, cardiovascular and gastrointestinal diseases.

I intend to run well-organized studies involving real patients, including a test of different connectors used on implants for holding dentures in place. This is needed to check if dentists can benefit their patients with new connectors and by using a minimum number of implants. This can reduce costs of dentures retained by implants and make their use possible in elders, who usually have small jawbones. I am also testing if a simple procedure, using a toothbrush to remove plaque from the roof of the mouth, can reduce inflammation in the mouth. This kind of problem is very common in people who use dentures and is produced by accumulated microbes that can cause other diseases.
