Abstract

Objective To analyze the association between mandibular vertical asymmetry and the presence of TMD in adult patients. Methods This case-control study recruited patients from the orthodontic clinic at FEBUAP. Patients were classified on the basis of diagnostic criteria for temporomandibular disorders (DC/TMD). Panoramic radiographs were measured to determine mandibular vertical asymmetry indices according to criteria described by Kjellberg and Habets. Both methods (DC/TMD and index criteria) were standardized a priori. Results A total of 56 patients were analyzed, of whom 25 (44.6%) met the inclusion criteria and were divided into two groups (TMD group, n = 15; non-TMD group, n = 10). The highest asymmetry index was observed in the condylar neck, followed by the total condylar asymmetry index, but without significant differences between groups (p > .05). Conclusion There is no association (p > .05) between temporomandibular disorders and mandibular vertical asymmetry.
