ABSTRACT
Fresh dental calculus were scratched and rinsed with distilled water, and then dissolved by HNO3. Simulated body fluid was used as control. Aqueous ammonia was added to step up the pH. FSEM and FI-IR were used to analyze the crystal character of deposition. Turbid occurred when pH = 5.4 and deposition occurred when pH = 5.6. Ribbon-like crystal, which was the same as the crystal in natural dental calculus was observed in experimental group and was evidenced to be hydroxyapatite (HAP) by FT-IR. HAP formation through homogeneous phase redeposition of dissolved dental subgingival calculus may be related with the existing template molecules in dental subgingival calculus resolution, which induce the biomineralization of HAP formation.
