Using chemical precipitation, and synthesis of hydroxyapatite for raw material preparation hydroxyapatite toothpaste. Through the hydroxyapatite of bovine serum albumin, toothpaste, soluble starch adsorption experiment and teeth to mineralization experiments show that the adsorption of toothpaste, mineralization and join the best proportion of hydroxyapatite. Results: containing hydroxyapatite 2.000 % ~ 3.000 % of hydroxyapatite toothpaste on protein, soluble starch is best adsorption, protein, soluble starch adsorption ability is blank 3.632 toothpaste 3.708 times and 2.794~2.899 times, and can make off ore tooth enamel again mineralization.
