[Association between craniofacial structures adolescents and temporomandibular disorders].

Objective To determine the association between craniofacial structures and the presence of TMD in adolescents. Material and Methods Cases-control study. 46 patients aged 10 to 16 years old were evaluated with their respective lateral cephalometric X-rays (23 cases and 23 controls matched for age and sex). The TTM was evaluated with the research diagnostic criteria for temporomandibular disorders (RDC/TMD). Results The comparison between cases and controls of the craniofacial structures did not show significant differences, however the lower facial height, facial axis and the mandibular plane were slightly higher in the group of cases. In the two-way analysis of ANOVA (diagnosis and age), facial convexity presented differences between the adolescent with and without temporomandibular disorders (p=0,002). Conclusion Craniofacial structures are not associated with the diagnosis of TMD in adolescents. However, changes occur in relation to the former location of the jaw, resulting in a skeletal pattern class II and an elongated shape of the face.
