Their availability even in severe disasters and decomposed bodies makes them invaluable for identification. In such cases, the teeth form an important material as they are hardest and chemically most stable tissues. Although DNA analysis is the most precise technique to determine the sex, sometimes lack of facilities and the cost factor may be a hindrance. The purpose of this study was to evaluate the probability of determining gender using maxillary CI, buccolingual (BL), and mesiodistal (MD) dimensions of maxillary first molar and to compare the efficacy of these parameters with each other.ĭetermination of sex is of immense importance in forensic investigations. In cases where only part of the skull with maxilla is obtained, maxillary indices may have to be used for sex determination. Mandible being a single bone that is not directly attached to skull poses increased chances of trauma or damage. Despite being reliable, the mandibular canine index (CI) has its limitations. Various odontometric parameters have been used for gender determination such as mandibular and maxillary canine indices, mandibular canine dimensions, maxillary canine dimension, maxillary first molar dimensions, and cumulative dimension of all teeth. Hence, today, dentist's opinion is often sought to answer queries that arise during a postmortem investigation. However, odontometric methods are more reliable in case of pediatric cases as teeth complete their development before skeletal maturation.
Measurement of long bones particularly humerus and femur, pelvis, or skull are often used for sex determination. Prediction of gender makes the task simpler since the missing person of only one gender is to be evaluated. Hence, they can be considered for gender determination.
The teeth being the most durable tissue of our body exhibits the least turnover rate because of its intense resistance to destruction.
