摘要：Introduction Cementum is a surface layer present in the teeth which is seen below the dentin in the root area. It is thin at the middle region of the tooth and thick at the apex region of the teeth. Specialized cells called cementoblasts form the cementumlayer.The age estimation done by using cementum is a better method to obtain positive result value which gives estimated value that is almost equal to the actual value. Aim:The main purpose of the study is to show that the dental students have knowledge and awareness on estimation of gender and age by using tooth cementum. Materials and method Self administered questionnaire of close-ended questions was prepared and it was distributed among dental students from February to April 2021 through the online survey “google forms”. The collected data were checked regularly for clarity, competence, consistency, accuracy and validity. Demographic details were also included in the questionnaire. Results79% of dental students accepted that teeth can be used for the age estimation and only 21% of them didn’t accept that teeth can be used for the age estimation. 69% of the respondents said that first use of cementum in human age estimation began with the number of incremental lines and 31% of them said that cementum in the human age estimation began with the width of the total cementum layer, 70% of respondents said that cementum can be used for estimating age and 30% of respondents said that cementum can’t be used for estimating age. Chi square analysis was done between the year of study and whether age estimation would be done using the cementum, where most of the undergraduates said that cementum can be used for the estimation of age, however, it is not statistically significant (Pearson’s chi square value = 2.324, df =1, P value = 0.127(>0.05)). Conclusion From this survey, we can say that dental students have knowledge about various methods for the estimation of age by using the cementum. Further studies can be done by using secondary dentin with various methods for finding gender and age of an unknown individual.
