Abstract：AIM:Exostoses on mandible and maxilla from excavated skeletons of Xi'an people about 1000 BC were measured in order to explore the relationship between the formation of exostoses and masticatory stress as well as oral health status. METHODS:40 excavated skeletons of about 1000 BC, were chosen for examination of exostoses on maxilla and lingual mandibule(LME). Other parameters, such as the morphology of temporomandibular joint, oc-clusal wear of molars, occlusal wear rate of molars, carious lesions, antemortem tooth loss, calculus and alveolar absorption levels were also measured. Data was analysed with SPSS 14. 0 software. RESULTS:Both BE and LME showed significant correlations with disorders of TMJ. LME showed a moderate but positive significant correlation with the wear rate on molars. BE showed a significant correlation with carious lesions, antemortem tooth loss, calculus and alveolar bone absorption. CONCLUSION:Jaw exostoses can be a useful parameter to examine the changes during human mankind evolution.
