Gilles Lavigne is a dentist graduated from the University of Montreal. After practicing for several years, he begins a career as a researcher in pain, bruxism and sleep. He then completes his training in oral medicine at the Georgetown University in Washington and pursues a research internship in neuropharmacology (mechanisms of pain, NIH). He also has a PhD in trigeminal neuralgia at the University of Toronto. In 2009, he is awarded an Honorary Doctorate from the Faculty of Medicine at the University of Zurich. He is now: i) Professor at the University of Montreal of Medicine and Dentistry, ii) a Canada Research Chair in pain, sleep and traumatology at Montreal’s Sacré Coeur Hospital, iii) orofacial pain and sleep disorders consultant at the CHUM stomatology clinic and at a private ENT clinic, iv) acting director of research at the CIUSSS in the North of Montreal Island.



Awake and asleep orofacial activities such as clenching and teeth grinding are part of bruxism. Moreover, some tend to associate it with bracing and thrusting habits, and exclude light but constant teeth touching, hypertonic tongue thrusting and lip or objects biting activities.

Precision medicine has now emerged for almost a decade and is well-known for taking into account the psychological and medical state of the patient, his genetics and his expectations. The use of deep learning and/or artificial intelligence will allow over time finer tuning of diagnostics and therapeutic choices according to the impact of risk factors as well as the severity and the consequences of orofacial activities on the quality of life, sleep, and medical health. The notion of “patient partner” includes clear and unprejudiced information by which the patient will choose jointly and freely the management style that corresponds to his expectations and his condition.
