Abstract
The aim of the study: Was a comparative analysis of the structural features of the endodontic system and the thickness of hard dental tissues over the past ten centuries.
Materials and methods: 180 teeth of people who lived from the X to XX centuries AD were studied using cone-beam computed tomography in endodontic mode: the volume of the endodontic system and the thickness of hard dental tissues were calculated using the algorithm developed by us. The Pearson correlation coefficient and Student's t-test were calculated in Excel program, and the data was analyzed with GraphPad Prism 8 Statistics Guide statistical program.
Results: The most significant Pearson correlation coefficient was found between the volume of the endodontic system and the thickness of the enamel in the area of the support cusp (r=0.723) and had a linear relationship for ten centuries. The dynamics of changes in other parameters has a non-linear dependence. Changes in parameters occur in a wave-like way.
Conclusion: The article assesses variability of structure of endodontic system and variation of features of internal structure of teeth.
