Validity of Lamendin Technique for age estimation in Iranian People

background: After completion of tooth growth , the age estimation is very difficult & the usual method is to evaluate the change in tooth structure. The aim of this study was to evaluate the validity of Lamendin technique for age estimation in Iranian people. Methods: 50 single rooted teeth collected from dead bodies of known age & sex in L M O, Tehran. Immediately after atraumatic extraction, the height of Periodontosis [P] , Transparency of the root [T] and the P&T indices described by Lamendin were measured. Then the data were evaluated for estimating age by means of the formula described by Lamendin. Results: The mean actual & estimated ages had a highly significant difference. By dividing the ages of the examined samples in different groups, it was noted that the mean differences were not significant in age groups 30 - 40 & 40 - 50 and hence the formula had some validity in those age groups. Conclusion: As the Lamendin technique is simple & fast, the study must be done with larger sample in both sexes, so that a new formula may be obtained for Iranian people.
