Forensic odontology is the application of dental principles to legal issues. It is an investigative aspect of dentistry that analyzes dental evidence for human identification. Sex determination is a subdivision of forensic odontology, and it is important especially when information relating to the deceased is unavailable. Sex determination becomes the first priority in the process of identification of a person by a forensic investigator in the case of mishaps, chemical and nuclear bomb explosions, natural disasters, crime investigations, and ethnic studies. Determination of sex/gender using skeletal remains presents a great problem to forensic experts, especially when only fragments of body are recovered. Forensic odontologist can assist other experts to determine the sex of the remains using teeth and skull traits. Various features of teeth such as morphology, crown size, and root length are characteristics for male and female sexes. There are also differences in the skull pattern and skull traits of two sexes. These will help forensic odontologists to identify the sex of the remains.
