Direct pulp capping of permanent teeth in primates using a resorbable form of tricalcium phosphate ceramic

Abstract

A resorbable ceramic was placed over 22 surgically created pulpal exposures in an experiment. Histological evidence showed that formation of a dentinal bridge took place by direct apposition on the pulpal tissues that were treated with a ceramic form of tricalcium phosphate. Formation of a dentinal bridge appears to be predictable. The bridge is contiguous and thick, pulpal inflammation is minimal, and odontoblasts ore observed directly under and in contact with the bridge. The ceramic form of tricalcium phosphate appears to enhance the formation of a dentinal bridge in contrast with the calcium hydroxide that was used as the control.
