Abstract

Apatite is expected to be a useful material for artificial bones in surgery and artificial dental roots in dentistry. In particular, studies have recently been conducted into the reconstruction of teeth using Hydroxyapatite (HAp), and several supplements such as gum have become popular for keeping teeth in good condition. However, the decalcifying and calcifying processes are still not well understood. The aim of this research is to study the decalcifying and calcifying mechanisms of HAp. Specifically, the calcifying treatments were carried out on sintered pellets of HAp without pores using Phosphate Acid Maltodextrin (PMD) and Xylitol calcifying promotion agents. A natural calcifying liquid which simulates the situation within a human mouth was used as a reference. SEM, EDX, X-ray, IR and Raman measurements were used for the characterization of structures, morphologies, formed elements and physical properties. It was confirmed that a precursor material OCP was grown on the HAp pellet by the calcification treatment using each promotion agent.
