VERA LÚCIA LOPES MEDEIROS (*)
ABSTRACT
This work intends to analyze the dental wear pattern resultant of attrition between maxilla and mandible in a prehistoric population that lived at the Sambaqui of the Ilhote do Leste, which is situated in a little hill between the South and the East beaches, in a island, named Ilha Grande, that belongs to Angra dos Reis – in the south coast of Rio de Janeiro’s state. The analysis made in the samples of teeth and the dental arcades that are part of the collection that belongs to the Department of Biological Anthropology of the National Museum of Quinta da Boa Vista indicates that this population suffered dental wear from extensive to moderate intensity.
The examined set of molars showed that these were the teeth more affected by the wear. A significant difference among teeth of individuals of both genders was not noted. Concerning to the age band, it is possible to perceive that the young individuals had presented smaller degrees of wear when compared to the adult individuals. The only sample that belongs to a child already demonstrates the existence of dental wear of light uniform type, as much in superior maxilla as in the mandible.
