title: Clinical and radiological follow-up results of patients with untreated TMJ closed lock.
abstract: The purpose of this study was to compare clinical and radiological findings of untreated closed lock patients at least 22 months after initial diagnosis. Ten patients with closed lock in at least one joint who had received no treatment were included in the study. Clinically maximum mouth opening, joint pain and joint sounds were recorded. Radiologically position of the disc, disc morphology, bone degeneration and presence of fluid were determined on magnetic resonance imaging. Clinical and radiological examinations were repeated 2-5 years after initial examinations. Results were statistically compared using either the non-parametric McNemar test or the Wilcoxon signed-rank test. There were significant improvements in both mouth opening capacity and prevalence of joint pain, while no significant change in radiological examination. The results of this study suggested that closed lock patients undergo active adaptation in clinical symptoms.
