Comparison of enamel and dentin microhardness of healthy and fluorotic teeth
AbstractThe aim of this study was to compare the enamel and dentin microhardness of teeth with TF (Thylstup-Fejerskov) scores of 0,1,2,3 and 4, using microindentation method. In this study we used Hanemann VEB Zeiss Jena device. The results demonstrated a decrease of the microhardness of the teeth having dental fluorosis when compare with healthy teeth, but the association was statistically significant only in the internal third of the enamel of the teeth having TF scores of 2,3 and 4 and at the enamel-dentin junction of the teeth with TF 4.
