Abstract

Purpose: The goal of this report was to investigate if panoramic radiography would be a suitable tool in diagnosing temporomandibular joint disc displacement. Methods: The sample comprised 56 female patients divided into three groups: (1) Control (n=30); (2) disk displacement with reduction (n=17); and (3) disc displacement without reduction (n=9). All patients were evaluated based on the Research Diagnostic Criteria (RDC/TMD). Linear and angular measurements as well as proportion determinations were obtained from tracings of panoramic radiographs and they were compared with condyle and disc positioning obtained from Magnetic Resonance Imaging (MRI) to find any predictive measurement correlated to disc displacement with or without reduction. Relationship to clinical signs and symptoms of temporomandibular dysfunction (TMD) were also evaluated. Results: The results revealed no significant differences between the three groups regarding the variables studied on the radiographs. Moreover, there were no significant correlations between the radiographic variables and clinical signs nor between the radiographic and MRIs variables (p>0.05). Conclusion: The use of panoramic radiography imaging exam for diagnostic predictions in clinical practice is not advisable.
