Abstract: Endodontic treatment can result in the extrusion of dental sealant material beyond the apex of a tooth. Dental sealant materials are known to have potentially cytotoxic properties and can cause damage to biological structures. This article describes the case of a patient who had experienced a sustained painful dysaesthesia of the left inferior alveolar nerve as a result of extrusion of material beyond the apex of the tooth into the nerve canal, and the surgical approach taken to directly treat the nerve and improve her symptoms.

Clinical relevance: Awareness of the potential and sustained effects of dental sealant material on biological tissue, as well as the proximity of important anatomical structures, such as the inferior alveolar nerve, will help practitioners in the safe treatment of patients. Additionally, an awareness of the signs and symptoms of foreign body reactions within soft tissues will aid diagnosis and prompt onward referral for specialist treatments.

Objective: The reader should understand the cytotoxic properties of dental sealant materials and their effect on biological structures. Clinicians should be aware of the unwanted effects of extruded root canal material.
