Randomized Controlled Trial Clinical TrialTreatment of temporomandibular disorders among adolescents: a comparison between occlusal appliance, relaxation training, and brief information.
In a randomized trial the effects of occlusal appliance and relaxation therapy, each combined with brief information, were compared with brief information only, in adolescents with temporomandibular disorder (TMD) pain. One-hundred-and-twenty-two adolescents (93 F and 29 M aged 12-18 years) were randomly assigned to one of the following 3 groups: brief information + occlusal appliance (BI + OA), brief information + relaxation therapy (BI + RT), or brief information (BI). Included were subjects reporting pain once a week or more often, in addition to receiving a diagnosis of TMD according to the Research Diagnostic Criteria (RDC/TMD). ⋯ Analgesic consumption was also significantly more reduced in the BI + OA group compared to the BI group. However, no significant differences were found between the treatment groups in jaw opening or in muscle and TMJ tenderness scores. Occlusal appliance was found to be superior to both relaxation therapy and brief information regarding pain reduction and can therefore be recommended when treating adolescents with TMD pain.
