Microorganisms play a major role in initiation and perpetuation of pulpal and periapical diseases. Therefore, elimination of the microorganisms present in the root canal system is the fundamental objective of endodontic treatment. Various chemical solutions, i.e. root canal irrigants are used for disinfection of which sodium hypochlorite (NaOCl) remains the gold standard solution. This is because of their broad antimicrobial spectrum as well as their unique capacity to dissolve necrotic tissue remnants. This paper reviews the different aspects of NaOCl and its use in endodontics. For this, MEDLINE database was searched by using PubMed search engine for all English-language articles published from January 2006 to March 2014 related with endodontic irrigation. Six hundred and two articles were selected, out of which 245 were not considered as they were of no significance to us. Chemical and toxicological concerns related to their use are discussed, including different approaches to enhance local efficacy without increasing the caustic potential.
