Aims: The present study is taken in account to determine the age and gender related prevalence of TMDs on the basis of signs and symptoms based on the RDC/TMD criteria. Materials and Method: The present cross-sectional study was conducted in the Department of Oral Medicine and Radiology. A total of 1009 patients aged between 6 and 80 years with a mean age of 42.04±16.8 years seeking dental treatment from January 2016 to June 2017 were included in the study. All the subjects were screened for TMDs signs and symptoms. The demographic data and the signs and symptoms of TMDs were recorded in respect to age and gender in designed structured questionnaire which were based on the RDC/TMD criteria. Results:The association between signs and symptoms based on the RDC/TMD criteria and gender was evaluated in study population by Chi-Square test. The clicking sound and deviation of mandible on mouth opening is more prevalent in males than females and both are statistically significant (P<0>).Crepitus and joint tenderness is more common in females. The joint tenderness in both sexes was highly significant (P0.05).When signs and symptoms based on the RDC/TMD criteria was compared in age groups, it was found that clicking sound and pain on mouth opening is most prevalent in <18years>65 years age group. All the three parameters were statistically significant (P8years>65 years age group.
