THE AIM OF THE STUDY: To study the trace element composition of various areas of hard tooth tissues in caries, pathological attrition and periodontal diseases on the archaeological material of dental remains of the X-XX centuries.
MATERIALS AND METHODS: The microelement composition of hard dental tissues of X-XX centuries' teeth was analyzed using the TM 3000 electronic microanalyzer (Hitachi, Japan).
RESULTS: The patterns of microelement composition in diseases of hard dental tissues and periodontal disease have been revealed. The results of two-factor analysis of variance confirmed a statistically significant dependence of the average values of O and C content in enamel over the centuries (p<0.0001), the average values of P, Zn, O and Mg in dentin (p<0.0001), the average values of O and C content in cement (p<0.0001). High correlation between Ca and Sr in enamel (Pearson's r=0.847; t-criterion=7.98; statistical significance p<0.01; n=27) and a noticeable correlation in dentin (Pearson's r=0.512; t-criterion=2.46; p<0.05).
CONCLUSION: The results indicate that with the relative constancy of anatomical and morphological characteristics, the variability of the mineral composition is observed, as well as its pronounced dependence on exogenous factors.
