RESUMO
BACKGROUND: Temporomandibular disorders (TMDs) are prevalent multifactorial pathologies in which the actual role of the cervical region position is controversial. OBJECTIVE: To analyze the relationship between the position of the upper cervical rachis and the symptoms of TMD. METHODS: Sixty women were recruited to this study. All of them completed a questionnaire and were subjected to a temporomadibular exploration to create two different groups: a TMD Group (n= 30) - women who suffered TMD symptoms according to the evaluation; and a control group (n= 30) - women who were free from TMD symptoms. Two X-ray examinations were performed in all the women: a lateral one and a frontal one with mouth open to assess the C1-C0 distance and the craniocervical angle. RESULTS: ANOVA showed that the TMD and control women had similar C1-C0 distances and craniocervical angles (p> 0.05). Pearson correlation did not indicate any relationship between the craniocervical position and the symptomatology of TMD (r=- 0.070). CONCLUSIONS: TMD symptomatology is unrelated to alterations in craniocervical position (C0-C1 distance and craniocervical angle). Women with and without TMD showed a similar prevalence of alteration in the craniocervical position.
