Abstract
The purpose of the study was to determine the prevalence of clinical signs and symptoms of temporomandibular disorders (TMD) in a young adult non-patient population and to investigate the possibility of an association between TMD and occlusal factors. A questionnaire including data from history and clinical functional examination was used in the study. All subjects (a total of 230) were male (army recruits), from 19 to 28 years of age (mean 21.3 ± 2.1). The study indicated that 38% of subjects had at least one symptom (subjects with slight, moderate and severe discomfort), while 45% of subjects had at least one sign of TMD. Spearman's rank correlation test showed weak but statistically significant correlation (p < 0.05 and p < 0.01) between occlusal factors and TMD in a young adult non-patient population. Clinical signs and symptoms of TMD were weakly correlated with some occlusal factors (malocclusion traits (Angle classes II/1, II/2, III, and crossbite), slide between RCP and ICP ≥ 1 mm, midline discrepancy ≥ 2 mm, nonworking side interferences, horizontal overlap ≥ 5 mm) and parafunctional habits (teeth clenching and teeth grinding). However, the importance of association between TMD, occlusal factors and parafunctional habits should not be overstated (weak correlation), since this may lead to neglect of the many other causes of orofacial pain and dysfunction in a biologically multifactorial system.
