The present study focused on reliability of Johanson's method of age estimation in Indian population also the effects of gender and diet on its efficacy Total 731 healthy permanent teeth without dental filling and/or cavity were collected. The known age was ranging from 18 to 74 years with the mean age of 43 years. Every tooth was subjected to longitudinal section in a labio - lingual plane. The method according to Johanson was used for age estimation by analyzing six variables namely: attrition, periodontosis, root resorption, root translucency, secondary dentin deposition and cementum annulations. The effects of two variables i.e. gender and diet in age estimation studied.The results were statistically analysed by using person's correlation coefficient and regression analysis. The results showed strong correlation between actual age and estimated age. Age estimation on samples of teeth between genders showed significant correlation with the actual age and the age estimation on sample of teeth between vegetarian and non vegetarian also showed a strong correlation with the actual age.
Johanson's method is the best method for dental age estimation for forensic and anthropological analysis on the skeletal remains in India.
