Sodium hypochlorite accident--a complication of poor access cavity design.
A case is presented of soft tissue damage resulting from inadvertent injection of sodium hypochlorite through a perforation created during root canal treatment of a mandibular incisor. The importance of access cavity design to help avoid such complications is highlighted and the anatomy of the mandibular incisor is discussed. Measures to minimize the risk of a hypochlorite accident and its potentially serious complications are proposed.
