The temporomandimular disorder (TMD) is considered a set of muscle and joint disorders affecting the orofacialregion. Even with the current development of preventive dentistry you can still find individuals who need rehabilitation with conventional dentures regardless of the cause of tooth loss, TMD can affect edentulous patients, people with uni or bimaxillary dentures. The aim of this study was to determine the prevalence of TMD in patients using dentures, observing the relationship between gender, type of prosthesis, time using dentures, temporomandibular disorders and the presence of chronic pain. The sample consisted of 122 total or partial edentulous patients attended in dental clinics of University of West of Santa Catarina – UNOESC, evaluated through the Research Diagnostic Criteria (RDC). From patients examined, 37.7% presented a diagnosis related to myofascial pain (group I), for group II concerning articular dysfunction index was 68%, and group III, degenerative, was 64.8%, when the data relate with chronic pain we obtained a significant index for females (p = 0.021). It was observed that chronic pain was significant for Group I (p = 0.0001), for Group III (p = 0.005), and removing or not to sleep (p = 0.023).We conclude that the TMD is more prevalent in females. However, there was no difference among patients with unimaxilar or bimaxillaryprosthesis, nonetheless when related to TMD with chronic pain was found significance of it due the fact of removing or not the prosthesis to sleep, and for the TMD patients in Group I and Group III.
