Abstract　： [Introduction] Recently, genetic engineering based on molecular biological techniques has progressed to such an extent that in the field of forensic dental medicine the use of racemization and DNA analysis have been made possible for estimating the age and determining the sex of the subject. On the other hand, the police dental surgeon officer system has been widely adopted across the country in 40 or more capitals and prefectures, and as part of postgraduate education, dental inspection by dentists has come to be stressed. Taking this situation into account, we would like to discuss the subject in three sections. [Teeth and Analyses Based on Racemization] The racemization of amino acids has been utilized in the field of archaeology as a means of determining the era of geochemical materials such as animal or plant fossil and accumulation strata. The same method was applied for the first time by Helfman et al.(1975) to estimate the age of teeth. Using 19 teeth, they determined separately the amount of L and D types of aspartic acid in their enamels, and found that the D/L ratio of a tooth and its age had a correlation coefficient of 0.921.
