Phosphophoryn is an important protein in dentin mineralization. It was combined with type I collagen sponge or alginate sheet as trial materials for direct pulp capping. The trial materials were placed onto the exposed pulp in maxillary first molar of 8 week-old Wistar rats. Rats were sacrificed 2-4 weeks after operation, and teeth were analyzed by SEM. In evaluation of reparative dentin formation they were compared with calcium hydroxide, a conventional material. The phosphophoryn combined with type I collagen or alginate induced thick reparative dentin that has dentinal tubules, intensively and quickly. Therefore, phosphophoryn was suggested to be a strong regenerator of dentin.
