Abstract

OBJECTIVE: To investigate the effect of dentin phosphoprotein (DPP) in inducing dentinal mineralization. METHODS: Human DPP was combined with EAH-Sepharose 4B beads and its function of inducing mineralization was studied in mineralization system in-vitro. The mineral formed on the surface of the beads was analyzed by scanning electron microscopy (SEM) and the structure was analyzed by X-ray diffraction and plasma emission spectrum. RESULTS: There was mineral formed on the beads with combined DPP and the mineral was calcium phosphates whose ratio of calcium to phosphate was 1.33. The diffractogram of the formed mineral was more similar to hydroxyapatite than to other calcium phosphates. CONCLUSION: When tightly combined with certain support substance, human DPP can induce mineralization.
