Dental pathology is an informative method of determining the type of diet upon which prehistoric populations subsisted. This study forms part of a larger anthropological investigation of the radiographic record of burials from the Kombumerri Aboriginal Tribe's ancestral burial ground at Broadbeach on the Gold Coast. It specifically exam ines the dentitions of the skeletal remains and the associated pathology with the intent of making some judgements upon the nature of the subsistent diet of the tribe. The Broadbeach osteological collection was returned to the descendants of the tribe following a claim for reburial in 1985, however radiographic and photographic records of 35 adult male individuals are available and form the basis of this study. This sample was complimented by a representative sample (n=3 8) of pre-European Aboriginal remains from throughout Queensland. Rates of dental pathology, injury and variation were calculated from the examination of the radiographic and photographic records of the sample and were subsequently analysed. It was found that there was a relatively large percentage of wear-caused abscesses (4.04%), moderate to severe periodontal bone loss and heavy attrition (of which the mandibular molars were the most severely affected). Caries incidence (0. 83 %) was low for normal hunter-gatherer populations. A large number of pulp chambers had a distinctive "cruciate" morphology due to excessive secondary dentine formation, as well as pulp stones. Injuries and abnormalities included central incisor a vulsion (58.38% - a significant difference to the rest of the dentition combined, P<0.01), and large taurodontic pulp chambers. These results support the hypothesis that the Kombumerri tribe were a hunter-gatherer population subsistent on an abrasive diet which consisted in part of marine foods.
