Online published on 3 January, 2019. Abstract 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<0.05).Crepitus and joint tenderness is more common in females. The joint tenderness in both sexes was highly significant (P<.001) However crepitus was statistically not significant (P>0.05).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 of age groups however crepitus was more common in>65 years age group. All the three parameters were statistically significant (P<.001) in age groups. The joint tenderness was most common in 36 to 50 years group while Deviation of mandible on mouth opening was more prevalent in 51–65 years of age group. Conclusion There is strong association between sign and symptoms of the RDC/TMD criteria and age and gender of patient's i.e the clicking sound and deviation of mandible on mouth opening is more prevalent in males however crepitus and joint tenderness is more common in females. Clicking sound and pain on mouth opening is most prevalent in <18years of age groups however crepitus was more common in>65 years age group.
