This paper presents the results of hereditary and enviromental dental findings in the identification of human remains exhumed from mass graves in the Republic of Croatia. A total of 17880 teeth from all  categories (incisors, canines, premolars and molars) were examinated. Hereditary findings of the teeth such as shape, size, position, as well as the age were used in all of the cases in order to confirm and complete identification. Only in 15% of the cases they were the starting point of the indetification process that would later be confirmed with another 3- 5 traditional indetification procedures. Distrubances in tooth eruption were recorded in 22% of  the cases, impaction of the teeth in 10%, and retarded eruption of teeth in 12%. Distrubances of tooth position or malocclusions were recorded in 65% of the cases. Tooth rotation in 26% and diastema median in the maxillar or mandible in 39%. Disorder in the tooth number in the form of unilateral and bilateral missing of lateral maxillary incisors were recorded only in 2% of the monitored cases. Abnormalities of the teeth shape were recorded in 11% of the cases, the majority of them were found on the tooth crowns 6% and less on the tooth roots 5%. Enviromental dental  findings that were the most significant for identifications were: prosthetic appliances in 30% of cases. Prostheses were helpful in the identification  of 3% of the cases, while crowns and bridges were helpful in 27% of the cases. Ante mortem teeth extraction was helpful in 25% of the cases. Teeth restorations were recorded in 20% of the identified cases, amalgams in 19% and aesthetic filings in 1%. Dental caries was helpful in 10% of the cases, superficial caries in 3% and caries of dentin in 7% of the cases.
