Development of micromechanical properties across carious areas of human tooth and dental filling
Original language description
The main focus of this paper is to describe the distribution of micromechanical properties (reduced modulus Er and hardness Hit) of human tooth treated with dental filling. The enamel and secondary dentin are carious and exhibit a decrease in the values of mechanical properties and following application of amalgam filling causes inconsistent interconnection of individual layers. The analysis was carried out on 2 samples of teeth n.37, extracted due to presence of an advanced stage periodontitis chronica. The amalgam-treated samples come from a woman (48 years) and a man (26 years). The most observable differences occur in the dentin area, where Er values differ as much as ~ 30 GPa in the central area and ~ 8 GPa in the dentin-amalgam interface. Differences in the area of enamel are not as significant, ranging from ~ 103 GPa in the central area to ~ 91 GPa in the enamel-amalgam interface. The mean Er of amalgam filling is ~ 65-71 GPa.
