    The study researched the reliability and sensitivity of an automated biometric recognition software in analyzing tooth prints. During research, enamel rod end patterns were obtained three times from a specific area on the labial surface of ten extracted teeth using acetate peel technique. The acetate peels were subjected to analysis with VeriFinger SDK software to obtain the enamel rod end patterns (tooth prints) and respective minutiae scores for each tooth print. It was found that VeriFinger software was able to identify duplicate records of the same area of a same tooth with the original records stored on the database of the software. Comparison of the minutiae scores using Cronbach's test also showed that there was no significant difference in the minutiae scores obtained.
