Anti-bacterial agents, such as silver nitrate, phenol with and without camphor, chlorhexidine and eugnol have been used in an attempt to “sterilize” dentin after cavity preparations. However, their effectiveness as dentin sterilizers is questionable and their cytotoxicity can cause inflammatory changes in the underlying dental pulp. Other irritating agents include alcohol, chlotofrom, hydrogen peroxide. They may also cause inflammatory change of the pulp.
