AIM OF THE STUDY: The aim of the present study is to analyse and assess the enamel rod end patterns for personal identification in normal healthy teeth and fluorosed teeth. MATERIALS AND METHOD: The present study comprises of two groups. Group I – fluorosed teeth (case group) and Group II – Normal teeth (control group). Age groups: 20 – 30 years, 30 – 40 years, 40 – 50 years. Each group comprises of 30 males and 30 females. 360 samples collected from 120 participants were considered for the analysis of tooth print pattern. The maxillary central incisor, canine and first premolar were selected. Enamel rod end pattern was recorded using acetate peel technique and analyzed using Verifinger® standard SDK version 11.1 software RESULTS: In the present study we have recorded and observed the tooth print pattern in fluorosed teeth and compared with normal tooth. Unlike the normal teeth which have a complete pattern, the fluorosed teeth showed an variation from complete to incomplete or inter-rupted pattern in our study. The difference in obtaining the enamel rod end patterns between normal and fluorosed teeth is statistically significant in central incisor and canine with p value 0.005 and 0.031 respectively but not in premolars where the p value is 0.06. The difference in obtaining the enamel rod end patterns between the age groups is not statistically significant with any of the teeth with p value 0.9 for central incisor and canine and with p value 0.43 for canine. The difference in obtaining in enamel rod end patterns between the gender is statistically significant among central incisor, canine and premolar with p value 0.006, 0.023, 0.022 respectively. CONCLUSION: Forensic odontology plays a very significant role in identification of deceased individuals based on the mortal remains of dental structures. Tooth print as a biomarker for personal identification is a recent evolving forensic concept. The technique is very simple and identification is based on the enamel rods end patterns on the outer surface of tooth. In the present study we have made an attempt to study the tooth print pattern in fluorosed teeth and have compared with the normal teeth. In our study we found a very unique complete to incomplete or interrupted tooth print pattern in fluorosed teeth in addition to the complete pattern. The application of these tooth print pattern as a reliable biomarker for personal identification requires further studies with larger sample size involving the entire dentition as well as studying all the surfaces of a single tooth.
