2022    Öcal, Fikri; Dayı, Burak

The inorganic content of teeth consists of calcium phosphate in the form of hydroxyapatite “ Ca5 (PO4)3 (OH) ” (Epple, Meyer, & Enax, 2019). Enamel tissue is a highly mineralized texture with an organized microstructure consisting of % 97 hydroxyapatites (P. W. Brown & Constantz, 1994; Legeros & characterization, 1981). The hardness and breaking strength of enamel derives from the structure formed by connecting hydroxyapatites to each other through organic matrix. The hardness and breaking strength of enamel derives from the structure formed by connecting hydroxyapatites to each other through organic matrix. Additionally, the enamel surface is coated with pellicle, which contains saliva proteins, carbohydrates, and lipids (Hannig, Hannig, & Kinderzahnheilkunde, 2007; Jowett, Marlow, & Rawlinson, 2013). The dentine tissue located at the under of the enamel layer is a bone-like tissue, which is approximately % 70 hydroxyapatite by volume and is rich in protein, mostly collagen, and the remaining part is water (Forien et al., 2015; Forien et al., 2016).
