[Calcium hydroxide cements in an in vivo study].

Great caution is required when choosing materials coming into direct contact with pulpal tissue. The aim of this study was to assess the connective tissue tolerance to Cap-cap and Cinacal, clinically used for pulp capping, in experimental animals. On the basis of tissue reactions around implanted material specimens at intervals of 2, 14 and 28 days after application, the two materials were found to belong to a group of biocompatible materials.
