Abstract
Relevance. The major- and trace-element composition of dental hard tissues varies with multiple exogenous and endogenous factors. This study reports statistically significant parameter shifts associated with different dental diseases. Using scanning electron microscopy, enamel, dentin, and cementum samples from individuals spanning the 10th to the 21st centuries were examined. The study aimed to analyze and compare the morphology and mineral composition of enamel, dentin, and cementum in ancient and modern teeth.
Materials and methods. The trace-element composition of the surface, middle, and deep layers of enamel, dentin, and cementum was assessed using a tabletop scanning electron microscope equipped with an X-ray microanalyzer (TM3000, Hitachi, Japan).
Results. Analysis of the tooth collection dating to the 10th–21st centuries showed a stable Ca/P ratio with substantial variability in trace-element concentrations.
Conclusion. Given profound differences in diet, lifestyle, and oral-hygiene practices over the past eleven centuries, these findings can inform strategies for the prevention of dental hard-tissue disease.
