Tooth reconstruction in forensic situations through dental materials: An anatomical art.

Abstract

Introduction:Dental identification is a frequently applied method of forensic investigation, in mass disasters, accidents, and criminal investigations, where the human remains are decomposed, charred, or skeletonized. However, in such events, teeth may dislodge due to postmortem loss or mishandling during transporting and packaging which may further hamper with the identification of an individual.Aim:To investigate the potential for reconstruction of missing teeth utilizing dental materials.Subjects and Methods:Impressions of the intra-alveolar morphology of the empty sockets of a mandible were taken utilizing different impression materials. Positive replicas were prepared, and the profile of the missing/absent dental roots and crowns was constructed. Standardized radiographs were taken to assess the reliability of the method.Results:Based on the subjective observation, the combination of light body and heavy body (Putty)-addition silicone (for negative replica), self-cure (pink-colored) resin (for positive replica), and flowable composite resin (for reconstruction) gave the best outcome among the materials used.Conclusion:Tooth reconstruction utilizing dental materials that may help in comparative identification.
