Sažetak
The aim of the study was to investigate the range of mandibular movements and to analyze the difference in range of mouth opening, right and left lateral movements, and protrusive movement between patients with clinical diagnoses of temporomandibular disorders and asymptomatic subjects (control group) in a young male population. A total of 240 subjects, aged 19-28, were included in the study. The TMD sample comprised 180 patients (60 patients with muscle disorders ; 60 patients with disc displacement with reduction ; and 60 patients with muscle disorders and disc displacement with reduction) and was compared with 60 healthy control subjects. All participants were evaluated by the attending dentists at baseline by means of a physical examination of the masticatory system and a history questionnaire which included the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis I measures. Analysis of variance (ANOVA) with the post hoc Bonferroni criteria showed significant difference in ranges of mandibular movements between and within the groups of asymptomatic subjects and TMD patients for active mouth opening (p = 0.001), right lateral movement (p = 0.002), left lateral movement (p = 0.006), and protrusive movement (p = 0.05). It has been found that there are statistically significant differences in the range of mandibular movements that separate asymptomatic subjects and patients with muscle disorders and disc displacements with reduction in this young male population. However, we cannot conclude that measurements of active mandibular movements can discriminate one group (TMD patients) from the other (asymptomatic subjects), because the mean ranges of these active movements between the groups were measured in clinically "normal" values.
