Root canal treatment is an essential part of general dental practice. Sodium hypochlorite (NaOCl) in various concentrations is the most widely used endodontic irrigant, but it can be irritant to vital tissues. This study presents a clinical case of tissue damage related to NaOCl extrusion to the apex during root canal treatment. A 45-year-old woman with moderate pain, dental crown fracture with healthy apex of first upper right premolar, was accepted into clinic for treatment. Pulpar necrosis was diagnosed and root canal treatment was performed. Bruises and severe inflammation of the right side of the face appeared immediately after irrigation and extrusion of NaOCl 5.25%. To avoid this type of accidents it is essential to recognize the signs and symptoms that occur immediately after projection. Also, must be consider it as an operational accident that can be mainly prevented by the use of side exit needles for root canal irrigation and a minimum of 2 mm short of the working length.
