Abstract / Description of output

In the field of human osteology, sex estimation is an important step in developing a biological profile. There are a number of methods thatcan be used to estimate the sex of human remains, varying from visual assessments to metric analysis of sexually dimorphic traits. Teethare one of the most durable physical elements in the human body and thus can be very successfully used for this purpose. The presentstudy investigates the utility of cervical measurements for sex estimation through discriminant analysis. The permanent molar teeth of75 skeletons (28 females and 52 males) from the Hasanlu site in north-western Iran were studied. Cervical mesiodistal and buccolingualmeasurements were taken from both maxillary and mandibular first and second molars. Discriminant analysis was used to evaluate theaccuracy of each diameter in assessing sex. The results showed that males had statistically larger teeth than females for maxillary andmandibular molars and cervical mesiodistal and buccolingual measurements (P < 0.05). The range of classification rate was from 78.4% to87.1% for the original and 78.4% to 85.5% for cross-validated data. The most dimorphic teeth were the maxillary and mandibular secondmolars, providing 87.1% and 86.1% correct classification rate respectively. The data generated from the present study suggested thatcervical mesiodistal and buccolingual measurements of molar teeth can be useful and reliable for sex estimation in Iranian archaeologicalpopulations.
