Effectiveness of Nanohydroxyapatite on Demineralization of Enamel and Cementum Surrounding Margin of Yttria-Stabilized Zirconia Polycrystalline Ceramic Restoration

<div>Vickers microhardness of enamel and cementum was determined before material application (<i>B</i><sub>M</sub>), after material application (<i>A</i><sub>M</sub>), and inducing demineralization (<i>A</i><sub>D</sub>) (5 locations each; with 100 microns apart) at 40 microns from enamel-resin cement junction and cementum-resin cement junction.</div>
