In forensic investigations commonly the individuals are identified using various methods, such as visual identification method by a family member, personal information, medical information, footprint records, dental records, clothing, and fingerprints. But these methods need antemortem data for comparison. Also in some circumstances, the body of the victim is damaged or disfigured. In both these situations, conventional methods of identification are not useful. DNA profiling plays a valuable role for the identification of victim in such conditions. DNA can be collected from several body tissues and organs of the body and also from human teeth. As tooth is a sealed box-like structure, DNA remains preserved for longer time even under adverse conditions. The quantity of DNA extracted from teeth depends on various factors; these factors include the type of tooth, age, and sex of an individual. This article outlines various methods of DNA profiling and also methods of DNA extraction from human teeth.
