title: Sodium hypochlorite chemical burn. Case report.
abstract: Sodium hypochlorite (NaOCl) is a well documented and widely accepted intracanal irrigant used to disinfect the pulp space in endodontic therapy. NaOCl can be an extremely cytotoxic material; therefore, care must be taken with its use. The authors present a case of periradicular extravasation of NaOCl with sequelae of pain, swelling, ecchymosis and parasthesia consistent with a chemical burn. The patient was treated with a nonsurgical medical management approach. She experienced a complete resolution of signs and symptoms, aside from a persistent residual focal parasthesia.
