Background: The onset of temporomandibular joint disorders (TMDs) cannot be predicted. No method of prevention of these disorders has been demonstrated. Once it occurs, cure cannot be assured. Even though magnetic resonance imaging techniques are the gold standard for evaluating TMJ pathologies, it is still costly and not easily available to all spectrums of patients. Hence, under the light of above obtained data, we planned the present study to assess the cephalometric characteristics in TMD patients. Materials & methods: A total of 50 patients with symptomatic TMDs were included in the present study and were categorized under the study group. Another set of fifty subjects of comparable age and gender were also included in the present study. Lateral cephlametric radiography was done in all the subjects. Following parameters were analysed: SNA°, SNB°, ANB°, SN-MP°, AR-Go (MM), UI-SN° and LI-MP°. All the data was recorded in Microsoft excel sheet and were analysed by SPSS software. Results: Among the 50 subjects of the study group; 20 subjects were of unknown aetiology, while 12 subjects, 8 subjects, 6 subjects and 4 subjects belonged to the missing teeth group, dental procedure group, orthodontic treatment group and Occlusal discrepancy group respectively. Significant results were obtained while comparing the SNA°, UI-SN° and LI-MP° cephalometric parameters in between the study group and control group respectively. Conclusion: In subjects with TMDs, there had been reduction in the forward development of maxilla, along with reduction in the inclination of upper and lower incisors; highlighting their effect on development of TMDs.
