Calm group. Prevalence of craniomandibular dysfunction in white children with different emotional states

Malocclusion, oral parafunctions, dentofacial injuries, orthodontic treatment, and emotional states are factors that have been implicated in the etiology of craniomandibular dysfunction. In a sample of 386 white children, the number of children rated by their parents as calm was 250 (108 boys, 142 girls). Malocclusion and oral parafunctions are considered to be the causative factors in this group.
