An equimolar mixture of tetracalcium phosphate and dicalcium phosphate dihydrate, which displays solid phase buffer activity, converts to hydroxyapatite in water and sets in a short time at room temperature Cement in powder form was kneaded with Macllvaine's buffer solution and implanted in the dorsal subfascia of rats, in order to compare its histopathological effects with other endodontic sealers. Histological examinations indicated that the cement caused less infiltration of inflammatory cells into the surrounding tissue than was caused by the sealer.
