A novel method was developed to grow hydroxyapatite (HA) coatings oil the surface of enamel. The coatings were formed by hydrolysis of alpha-TCP for 6h at 37 degrees C. The detailed characterizations of the microstructure and mechanical properties of the coatings, and cytotoxicity of alpha-TCP hydrolysis Solution were performed. SEM and TEM analysis show that the HA coatings, approximate 20 mu m in thickness grow perpendicularly to the enamel surface, contacting well to the Surface of enamel. Vickers microhardness and wear-resistance tests indicate that there is no statistical significant difference of the hardeness and wear-resistance between the coatings and healthy natural enamel. The grade of cytotoxicity of alpha-TCP hydrolysis Solution is I grade, satisfying the relevant criterion oil biomaterials. The study Suggests that the hydrolysis of alpha-TCP is a promising method to effectively and conveniently restore and prevent. early enamel caries.
