The general population, not related as patients, can not be considered completely free of Cranio Mandibular Dysfunction (CMD) because epidemiological studies have been showing that up to 70% of aleatory individuals present signs or symptoms of this disorder. We believe they can influence the results and conclusions. Our purpose, based on this supposition, was to study two homogeneous sub-groups: individuals, classified by Helkimo 's Index as completely free of signs and symptoms (Ai 0, Di0) and with CMD (Ai II or Di II-III). These samples were analyzed considering the Occlusion Index, (Oi) and through a psychological test, Goldberg 's General Health Questionnaire (GHQ). We examined 50 people, 4 men and 46 women, affected with CMD (aged 13-49 years old with a mean of 28.1 years) and 50 more, 14 men and 36 women, without CMD (aged 20-56 years old with a mean of 25.1 years). Our results were tested by chi-square. We concluded that malocclusion was slightly more prevalente in CDM individuals, although not significant. Stress and other psychological factors were also slightly higher in individuals with CMD, with significance for sleep disturbances. The association of both factors were distributed evenly between the two groups, but the simultaneous absence of the factors was significantly higher in the people with no signs and symptoms. Self-related bruxism and oral parafunctions were slightly higher in CMD individuals with significance for clenching. The association between malocclusion and bruxism was similar for both groups, but the association between stress and bruxism was significantly higher for CMD individuals
