Abstract
A patient was brought to A&E by their GDP who had injected sodium hypochlorite (NaOCl) through a perforation in the patient's LR4, resulting in pain, swelling and immediate formation of a large, necrotic ulcer. Within 2 days, the patient developed paraesthesia in the distribution of the right mental nerve. Antibiotics and steroids were prescribed to alleviate the acute symptoms. The perforation was repaired with mineral trioxide aggregate (MTA) and root canal treatment was completed with the aid of a microscope. Review appointments were arranged to monitor healing of the injury.CPD/Clinical Relevance: Management of iatrogenic root perforation and associated NaOCl injury is useful knowledge.
