title: Temporomandibular disorder treatment outcomes: second report of a large-scale prospective clinical study.
abstract: Longitudinal studies of outcomes for temporomandibular disorder (TMD) treatment are rarely done and even when conducted often suffer methodological weaknesses. These may include the lack of valid outcome measures for symptom changes. This second report of a long-term multi-site study of 2104 treated, 250 untreated, and 44 long-term treated TMD patients is part of a continuing effort to study TMD treatment efficacy in a very large patient population. A validated symptom measurement system, the TMJ Scale, assured a valid and uniform assessment of treatment outcomes across a large number of practices. Data indicate that untreated TMD patients do not improve spontaneously over time and that patients treated with a variety of active modalities achieve clinically and statistically significant levels of improvement with no evidence of symptom relapse after treatment completion. The use of anterior repositioning appliance therapy produced better results than flat plane splint therapy.
