Enhanced bleaching effect of bovine tooth by hydrogen peroxide via calcium phosphate spheres

Abstract

<jats:p>In the study, calcium phosphate spheres (CPS) were prepared using phosphate buffer solutions by hydrothermal method and were used to manufacture a lab-made bleaching paste. The obtained paste was used to whiten bovine teeth in order to investigate whitening effect with CPS in the paste. The results showed that the bleaching paste made by CPS does not affect bleaching effect of hydrogen peroxide (HP). On the contrary, it can prolong the bleaching effect compared the pure HP.</jats:p>
