Pulp capping with hydroxyapatite ceramic in rat molars.

Abstract

Direct pulp capping with a hydroxyapatite ceramic in rat molars induced the formation of reparative dentin in the exposure sites after 2 weeks. In addition, foci of acute and chronic pulpitis were detected. After 6-8 weeks of application of the material partial or total necrosis occurred. The use of hydroxyapatite as a possible pulp capping material is discussed.
