Background: Calcium phosphate cements (CPC) are a group of biomaterials possessing wide scope of use in various branches of medical science.These materials have balicki stick been proposed to be highly biocompatible and osteoconductive.This study is based on a newly developed CPC formulation (Chitra-CPC) and is aimed at the evaluation of its biocompatibility through an Endodontic Usage Test in a porcine study model.Objective: To evaluate the periapical tissue reaction to Chitra-CPC when used as a root canal sealer/filler material in comparison with a resin sealer, AH Plus (Dentsply).Materials and Methods: The procedure was done on porcine animal model following the ISO 7405 criteria.

The material was implanted intentionally into the periapical area of 36 teeth through a root canal procedure carried out in six animals which were divided equally among 1-month and 3-month time periods.Results were based on the histological evaluation of the autopsied specimens after the prescribed time periods.Results: Mild to moderate periapical tissue reaction was found in Chitra-CPC samples belonging to the 1-month time period, whereas majority of the 3-month CPC samples showed an absence of inflammation.Samples of AH Plus in 1-month Dog Charms period showed severe to moderate inflammation, whereas 3-month AH Plus samples had a mild to moderate inflammation.Conclusions: Chitra-CPC is a biocompatible material.
