Sodium Hypochlorite Accident during Canal Treatment: Report of Four Cases Documented According to New Standards

Hypochlorite accidents are relatively rare events. Therefore, there is a lack of precise and accurate reports in the scientific literature that could help clinicians better understand phenomenon associated risk factors. This study reported four hypochlorite attributable to 5% NaOCl extrusion patients who had undergone treatment maxillary elements canal treatments. In all cases, occurred during irrigation phase were characterised by intracanal bleeding, ecchymosis, swelling on hemiface corresponding treated tooth. Antibiotics, paracetamol, NSAID, corticosteroids, cold or warm compresses for oedema prescribed treat symptoms accidents. Significant improvement was observed after 5–6 days. Anatomic factors such as apical fenestration, root perforation, large foramina identified possible After accidents, applied endodontic procedures which no evidence continue treatments, changing type irrigant method. Our results suggest using standardised approach document each accident will allow researchers collect more detailed data can subsequently be used identify potential manage symptomatology
