title: Sodium hypochlorite accident with evaluation by cone beam computed tomography.
abstract: OBJECTIVE
  To show the radiographic manifestation of sodium hypochlorite after accidental injection past the apical foramen and into the soft tissues.
  
  
  CONCLUSIONS
  A female patient was seen for an emergency visit after suffering a sodium hypochlorite accident at her general dentist's office. The patient was seen within 1 h of the accident and was in pain associated with facial swelling. Radiographs, including a Cone Beam Computed Tomography (CBCT), and photographs were taken. Endodontic emergency treatment was initiated. The patient was reassured and given pain medication and antibiotics. Follow-up visits were scheduled over 6 days when the swelling had resolved.
  
  
  CONCLUSIONS
  • Importance of multiple radiographic images during preoperative endodontic evaluation when undertaking endodontic retreatment. • Knowledge of apical anatomy as related to surrounding structures. • Effect of sodium hypochlorite when injected in the soft tissues.
