In vitro remineralization of acid-etched human enamel with Ca3SiO5
چکیده انگلیسی

Bioactive and inductive silicate-based bioceramics play an important role in hard tissue prosthetics such as bone and teeth. In the present study, a model was established to study the acid-etched enamel remineralization with tricalcium silicate (Ca3SiO5, C3S) paste in vitro. After soaking in simulated oral fluid (SOF), Ca-P precipitation layer was formed on the enamel surface, with the prolonged soaking time, apatite layer turned into density and uniformity and thickness increasingly from 250 to 350 nm for 1 day to 1.7-1.9 μm for 7 days. Structure of apatite crystals was similar to that of hydroxyapatite (HAp). At the same time, surface smoothness of the remineralized layer is favorable for the oral hygiene. These results suggested that C3S treated the acid-etched enamel can induce apatite formation, indicating the biomimic mineralization ability, and C3S could be used as an agent of inductive biomineralization for the enamel prosthesis and protection.
