RESUMO

Several image modalities have been used to access the condylar position in the glenoid fossa. However, despite the development of more advanced techniques for imaging of the temporomandibular joint, the transcranial projection remains widely used in dentistry. The purpose of this study was to compare the condylar position from transcranial projection (TRANS) and magnetic resonance imaging (MRI). Thirty five matched pairs of TRANS and MRI were evaluated. The TRANS were compared with the lateral, central and medial cuts of the MRI and the condylar position was accessed in the closed and opened mouth position, according to subjective and objective methods. Bowker?s test was used to analyze the data and there was no statistical significance between TRANS and MRI (p>0.05). The sensitivity, specificity and accuracy values were calculated for each group. Although a similar mean values between them, the comparison with the lateral cut showed higher values, which might be due to the fact that the TRANS represents the lateral one third of the condyle. It can be concluded that the TRANS seems to be an acceptable method, and its applicability as adjunctive method in the condylar position should not be rejected.
