Despite numerous studies on the prevalence of temporomandibular joint disorders (TMJDs) in adults, those performed in children are limited. This study determined the prevalence of TMJDs in 9-12-year-old Kermanian boy students living in Southeast of Iran. 240 boy students selected by randomized method and studied through a descriptive cross-sectional epidemiologic survey including interviews and physical examinations. Overall, 11.7% of the boys had TMJDs, 1.7% limitation in mouth opening and 5.4% deviation on jaw opening. Attention to temporomandibular joint disorders in children is necessary by preschool examination in order to prevent their progress in later stages of life.Iran J Med Sci 2005; 30(2): 91-93. Keywords ● Temporomandibular disorder ● children ● epidemiology
