“…A more recent method of sex determination from teeth is the presence of sex chromatin or Barr bodies in the pulp of the teeth [ 26 , 27 ], according to the method devised by Barr & Bertram [ 28 ]. The studies have also been carried out to extract DNA from the pulp tissue as well as dentine [ 29 , 30 ] and its use for sex determination using Polymerase Chain Reaction (PCR).…”

Forensic odontology is primarily concerned with the use of teeth and oral structures for identification in a legal context. Various forensic odontology techniques help in the identification of the human remains in incidents such as terrorists’ attacks, airplane, train and road accidents, fires, mass murders, and natural disasters such as tsunamis, earth quakes and floods, etc. (Disaster Victim Identification-DVI). Dental structures are the hardest and well protected structures in the body. These structures resist decomposition and high temperatures and are among the last ones to disintegrate after death. The principal basis of the dental identification lies in the fact that no two oral cavities are alike and the teeth are unique to an individual. The dental evidence of the deceased recovered from the scene of crime/occurrence is compared with the ante-mortem records for identification. Dental features such as tooth morphology, variations in shape and size, restorations, pathologies, missing tooth, wear patterns, crowding of the teeth, colour and position of the tooth, rotations and other peculiar dental anomalies give every individual a unique identity. In absence of ante-mortem dental records for comparison, the teeth can help in the determination of age, sex, race/ethnicity, habits, occupations, etc. which can give further clues regarding the identity of the individuals. This piece of writing gives an overview of dental evidence, its use in forensic identification and its limitations.

“…Similar results were obtained by Das et al .,[ 10 ] and Suazo et al . [ 19 ] in 2010 where they checked the efficacy of dental pulp in identifying gender and assessed its reliability as a tool in forensic dentistry. The results were similar to our study in which frequency of Barr bodies in females was more than that of males and were statistically significant (p > 0.005) and the mean number of Barr bodies in females were more than in males.…”

“…For accurate diagnosis, Barr bodies should be more than 6% and F-bodies should be up to 4% until a period of 4 weeks since death [13]. The only limitation for the use of this method is that any chromosomal anomaly can give negative or false positive results [14].…”

Forensic odontology is the branch of dentistry which aids in identifying human remains after homicides, accidents, wars or natural calamities. Forensic science has long been dependent on fingerprints or some identification mark on the body of a deceased individual. But in the absence of such evidence dental indicators assist successfully in the identification process. The study of teeth and the surrounding tissues of the oral cavity in order to establish the identity of a victim are known as dental profiling. Teeth can play a vital role in estimating the age, sex, race, socio-economic status, personal habits, oral and systemic health, occupation and dietary status of an individual. Various methods like radiographic imaging, dentin translucency, amino acid racemization, chromosomal analysis, barr bodies, amelogenin protein analysis, cementum annulations have made dentist an essential part of forensics.
