ABSTRACT

        FORMATION OF A FACIAL HAEMATOMA DURING ENDODONTIC THERAPY

         Background. Sodium hypochlorite, or NaOCl, is one of the most commonly used irrigating solutions in endodontic practice. Its clinically proven antibacterial, solvent and lubricating properties make it a very appealing choice as an intracanal medicament.

Case Description. The authors present a case of facial haematoma formation after an inadvertent injection of NaOCl into the periapical tissues. The NaOCl solution caused extensive tissue destruction. Management of the condition required the hospitalization, intravenous antibiotic therapy and multiple intraoral surgical incisions to facilitate drainage.

Clinical Implications. Use of NaOCl must be confined to the root canal system. This report reviews this intracanal medicament’s potential toxicity and emphasizes the need for clinicians to remain cognizant of possible problems while using the solution.

Use of sodium hypochlorite, or NaOCl, as a chemical adjunct to mechanical debridement of pulp canals is a common practice in endodontics. The solution’s solvent activity for both necrotic and vital tissues and its antibacterial and lubricating properties make it an attractive choice for intracanal irrigation in endodontic practice. However, if used injudiciously, NaOCl can be extremely toxic and destructive to cellular tissues. There have been a few published reports of untoward incidents, including accidental parenteral administration, with use of this solution.13

The following report describes a case of extensive tissue destruction and formation of a dissecting haematoma during a routine nonsurgical endodontic procedure. The tissue reaction was precipitated by an inadvertent injection of NaOCl into the periapical tissues. The article aims to emphasize the fact that clinicians should remain cognizant of this potential problem while using NaOCl. Adherence to sound endodontic therapy principles is likely to reduce the chances of such iatrogenic complications.
