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.
