Anatomical variations in the permanent mandibular canine: forensic importance

Introduction: The uniqueness of dental morphology plays an important role in Forensic Odontology, especially for human identifications, in which a single tooth can provide information for dental identification. Objective: To address the importance of a permanent lower canine with two roots for dental identification considering the internal and external morphology of the canine roots. Case report: To report a forensic case in which a two-rooted permanent lower canine was found in a decomposed human body. Conclusion: Although the victim was not identified by the dental parameter, it was observed that this type of morphological variation is of little incidence in some populations, therefore constituting a valuable tool for dental human identifications.
