Effects of Phosphoric Acid Pre-Etching on Chemisorption between Enamel and MDP-Containing Universal Adhesives: Chemical and Morphological Characterization, and Evaluation of Its Potential
Fei Han, Ruizhen Liang, Haifeng Xie
Abstract
= 0.009). Phosphoric acid pre-etching can increase the negative charge on the enamel surface and facilitate the chemical reactions of MDP and hydroxyapatite (HAp) to produce more calcium salts, thus improving the chemisorption between enamel and MDP-containing universal adhesives.
