title: Relationship between craniomandibular dysfunction and malocclusion in white children with and without unpleasant life events.
abstract: An epidemiologic study was conducted to investigate the relationship between craniomandibular dysfunction and malocclusion in 386 children aged 6 to 10 years with and without unpleasant life events. The results showed no statistically significant correlations between each clinical sign and each type of morphologic malocclusion in both groups. The chi-square test, however, revealed statistically significant correlation between the pain in the temple region and posterior crossbite in the calm group but not in the not calm group. With respect to the functional malocclusion, the chi-square test showed statistically significant correlations between interferences in the terminal hinge movement and TMJ tenderness and difficulties in opening wide. However, these correlations were found only in the calm group. When the definitional symptoms of craniomandibular dysfunction were aggregated, no statistically significant correlations were found between them and each type of malocclusion in both groups. The results of this study showed that the correlations between malocclusion and craniomandibular dysfunction were inconsistent.
