Context: Temporomandibular joint (TMJ) disorders represent a multifactorial disease process manifesting with various combination of signs and symptoms. Several studies have shown that there is an increased prevalence of TMJ dysfunction among females; however, there has been no conclusive explanation for this increased occurrence. Occlusal discrepancies have been identified as a causative factor in several cases. Aims: The present study was designed to identify the presence of three signs of occlusal discrepancy, namely the presence of anterior and/or lateral slide from centric relation to centric occlusion, occlusal contact on the nonworking side, and disclusive contact distal to canine on working side on purposeful lateral movement of mandible, in among the population with no signs of TMJ dysfunction. Methods and Materials: A sample population of 620 patients consisting of 313 females and 307 males with no signs of TMJ dysfunction were included in this study. Individual patients were examined for maximum inter-incisal opening, deviation of mandible on opening and closing, presence of joint sounds, and the three abovementioned signs of occlusal discrepancies. Results and Conclusion: The results revealed that there was no statistically significant difference in the occurrence of signs of TMJ dysfunction and of occlusal discrepancies among symptom-free men and women.
