there are several studies about the cytotoxic effects of dental materials in contact with the pulp tissue, such as calcium hydroxide (ch), adhesive systems, resin composite and glass ionomer cements. the aim of this review article was to summarize and discuss the cytotoxicity and biocompatibility of materials used for protection of the dentin-pulp complex, some components of resin composites and adhesive systems when placed in direct or indirect contact with the pulp tissue. a large number of dental materials present cytotoxic effects when applied close or directly to the pulp, and the only material that seems to stimulate early pulp repair and dentin hard tissue barrier formation is ch.
