Abstract
Aims: To investigate the prevalence of temporomandibular disorders (TMD), b ruxism, and other oval habits among drug addicts compared to a normal, non- addicted, matched control population, and to assess the detrimental effect of long-term drug abuse on the parameters studied. Methods: Subjects includ ed 55 drug-addicted patients (51 males and 4 females) randomly selected fro m long-term addicts using "hard" narcotics and attending a methadone mainte nance center and a control group of 52 normal non-addicted individuals (48 males and 4 females) matched to the addicts for age, gender, and socioecono mic status. A clinical examination and a questionnaire were used. One exami ner deter mined that all questions were correctly understood and answered, and a second examiner performed the clinical examinations and was unaware o f the results of the questionnaire. Results: The addicted group had a high prevalence of orofacial motor behavior (bruxing, clenching) as well as sign s and symptoms of TMD (morning headache, joint noises, joins and masticator y muscle tenderness to palpation, and tooth wear) compared to the controls. Active (voluntary) jaw opening was significantly smaller, although within an acceptable range when compared to the controls. Conclusion: Long-term dr ug abuse detrimentally affects the stomatognathic system, as expressed in a high prevalence of oral motor behavior and signs and symptoms of TMD.
