| Abstract |
Teeth are the most stable tissue in the human body and form an extremely durable material for use in anthropological, genetic, odontological and forensic investigations. Determination of sex and age from teeth is a very important subdivision of forensic odontology, which plays a major role in the identification of unknown individuals. The purpose of this study is to evaluate the association between sex and age on dental wear of the buccal and lingual surfaces of the teeth. A total of 132, first and second premolar teeth, extracted from Thai adult patients and cadavers were collected from the following sources: the Oral and Jawbone Surgery Clinic, Faculty of Dentistry and Department of Anatomy, Faculty of Medicine, Khon Kaen University. Tooth wear on the buccal and lingual surfaces was recorded using the tooth wear index developed by Smith and Knight. There was no significant sexual difference in the tooth wear score and a higher degree of both surfaces was found among males (p>0.05). The degree of buccal and lingual tooth significantly increased with age (p<0.05). Dental wear is concluded to be an important indicator of adult age at death.
