Abstract:
Objective: Orofacial system and teeth are common subjects of paleodontological research. On the basis of a detailed analysis of the preserved remains of the skull and teeth, we can gather important demographic information, such as gender and race, and estimate the age of the individual. The purpose of this paper is to present a technique for evaluating the dental hard tissue using a computer software which can be used for age estimation purposes in paleodontology. Methods: A collection of skeletal remains of the Croatian Academy of Sciences and Arts is used for research purposes. It comprises seven Croatian archaeological sites from two historical periods, late antiquity and the Early Middle Ages. Images of occlusal surfaces and incisal edges of teeth of upper and lower jaw were transferred to the computer software VistaMetrix Inc. Areas covered with enamel and areas of exposed dentine on occlusal tooth surfaces were outlined and sizes of areas were calculated and expressed in cm². Estimated chronological age and areas of exposed dentine were correlated and statistically analyzed using the Kruskal-Wallis test. Results: There is a statistically significant correlation between the total number of teeth with estimated chronological age (χ² = 46.3, p <0.001). The total number of teeth negatively correlated with chronological age. Spearman correlation coefficient rho = -0.370 (p <0.001). There is a statisticaly significant difference with total area of available teeth (χ² = 42 ; P <0.001), a total damaged area of available teeth (χ² = 50 ; P <0.001) and share (%) of the total damaged area percentage of available teeth (χ² = 97 ; P <0.001) compared to the estimated chronological age. Conclusion: According to the preliminary results, we expect that this study will provide a simple, fast and reliable method of evaluation of the dental age based on loss of dental hard tissue.
