Abstract: Objective: To investigate the characteristics of temporomandibular disorders (TMD) and analyze the potential risk factors for TMD in drug addicts. Methods: TMD related questionnaire survey and professional examination were conducted among 199 drug addicts in a compulsory detoxification center in one Chinese city. Results: 1)Joint noise, maxillofacial pain, and mandibular movement disorders were involved in 57.79% of the drug addicts during the past 3 months, and incidence of maxillofacial pain reached up to 42.72%; 2) 40.70% of the drug users had positive signs of TMD, with joint noise in 28.14%, mandibular movement disorders in 13.57%, and maxillofacial tenderness / pain during movement in 10.55%; 3) There was no close relationship between the duration of drug abuse and TMD symptoms and/or signs, but the incidence of TMD symptoms and maxillofacial pain was significantly higher in drug addicts with tension/anxiety and teeth clenching (P<0.05). Conclusion: As a multifactorial disease, there is no direct relation between TMD and drug abuse, but drug abuse related anxiety and clenching may be the risk factors of TMD.
