Sex Estimation through Morphometric Analysis of the Temporomandibular Joint
Abstract: The present study evaluated through a morphometric analysis the temporomandibular joint (TMJ) to estimate sex. Participants in a database with archived tomographic images of patients who sought the Radiology Clinic of the Hospital Universitário Oswaldo Cruz/University of Pernambuco for face or skull tomography were evaluated. Gender was recorded while the participant underwent the tomographic exam and was indexed in the database. The tomographies were recorded in DICOM format and were evaluated using the OSIRIX HD Software. The morphology of the mandibular fossa, the joint eminence and the condyle were evaluated. The measures were analyzed statistically, and results with p < 0.05 were considered statistically significant. Both the length of the right and left mandibular condyle (Aco-pco) showed larger dimensions in the male group with a statistically significant result (p = 0.003). The measurements of the glenoid cavity also showed statistical significance with the male gender presenting a higher measurement standard than the female. There was a statistically significant association between Morphology of the left articular eminence and sex. Conclusion: Some linear measures of the JTM indicated the possibility of establishing sexual differentiation and showed that the values referring to the male group tend to be higher than those of the female sex. Further studies with larger sample numbers are needed to achieve scientific evidence.
