Sodium hypochlorite (NaOCl) extrusion beyond the apex, also known as ‘‘a hypochlorite accident,’’ is a well-known complication that seldom occurs during root canal therapy. These ‘‘accidents’’ have been the subject of several case reports published over the years. Until now, no publication has addressed the global synthesis of the general and clinical data related to NaOCl extrusion.

A systematic review of previously published case reports to identify, synthesize, and present a critical analysis of the available data is available and contains a standardized presentation of reporting data concerning NaOCl extrusions to refine and develop guidelines that should be used in further case report series.

  • When talking about pain control during the accident, Dr. Roda was describing the concerns not to inject anesthetic too close to the accident site. The accurate statement should be: one needs to avoid the area where the accident has created a “bolus of hypochlorite” rather than a “bolus of anesthetic.”
  • Referring to post-op antibiotic use, the accurate date of the article mentioned in the Annals of Internal Medicine is 2012.
