Abstract

Sodium hypochlorite (NaOCl) is the most often used solution in root canal treatments due to its inexpensive cost and highly efficient antibacterial activity against diseased root canal microorganisms. Nonetheless, this solution can produce difficulties due to its cytotoxic properties. When this solution is injected into neighbouring tissues, the patient typically experiences excruciating pain, and an immediate therapy is required to prevent long-term complications. This article covers the clinical characteristics of three individuals who sustained unintentional NaOCl extrusion following endodontic treatment of variable severity and different therapies. In addition, it describes the long-term neurologic impairments that this type of accident may produce and suggests a treatment strategy for such cases.
