Abstract: Introduction: Sodium hypochlorite is a solution used in endodontic treatment, and if an accidental apical extrusion occurs, serious complications may affect soft tissue. Objective: The aim of this article is to present a case of apical extrusion of sodium hypochlorite (NaOCl) during root canal system instrumentation. Case report: A 28-year-old woman sought a local dental service for root canal treatment of tooth #24. Conventional endodontic treatment was adopted, which consisted of the use of 2.5% NaOCl solution as irrigation solution applied with a 10-ml syringe and 22G hypodermic needle. At that time, the patient reported extreme pain and a burning sensation in the left maxillary region, followed by the formation of intense edema. A clinical diagnosis of hypochlorite-induced cellulitis was made. The patient was treated immediately with amoxicillin (500 mg, orally) at intervals of 8 h for 7 days and dexamethasone (4 mg, intramuscularly) at intervals of 24 h for 3 days. In the subsequent endodontic treatment, 2% chlorhexidine gel applied with a 5-ml syringe and 24G needle was used as irrigation for a better control of treatment and to prevent new accidents. The root canals were instrumented using adequate crown-down technique, which provides a conical shape, and filled by lateral condensation technique. The patient was symptom free at the 8-month clinical follow-up. Conclusion: Dentists should always carefully follow all stages of dental treatment planning without neglecting any of them, paying attention to the solutions used and their storage as well as performing a specific technique with maximum accuracy. If an accident occurs, the appropriate handling of the situation will enable the satisfactory completion of treatment.
