Abstract
The present study evaluated through a morphometric analysis the temporomandibular joint (TMJ) to estimate sex. Participants in a database with arc hived tomographic images of patients who sought the Radiology Clinic of th e 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 signi ficance with the male gender presenting a higher measurement standard than the female. There was a statistically significant association between M or phology of the left articular eminence and sex. Conclusion: Some linear mea sures of the JTM indicated the possibility of establishing sexual differentiation and sh owed 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.
