Abstract
Sodium hypochlorite (NaOCI) is an effective intra canal irrigant and used in concentrations ranging from 0.5 to 5.25%. At these concentrations, it is highly hypertonic and strongly alkaline with pH 11 to 13. Sodium hypochlorite accident is a rare complication seen in endodontic therapy. It was first reported by Becker et al in 1974. Since then it has been infrequently reported in literature including cases of accidental misuse as a local anesthetic agent and accidental extrusion into maxillary sinus. Majority of NaOCl accidents has pulp necrosis, periradicular radiolucency as preoperative status. No specific treatment can reverse the damage due to NaOCl. Mainstay of treatment is supportive including airway protection, control of swelling, pain relief and prevention of secondary infection. Present article highlights a case of sodium hypochlorite accident and its successful management.
