Mandibular endodontic-related paresthesia

A 57-year-old woman sought treatment for mandibular swelling (of two weeks duration), pain, and paresthesia in the region of the left canine and first premolar. The teeth had undergone endodontic therapy; in addition, they partially supported a long-span fixed partial denture. The patient was concerned about the possibility of a serious neoplastic condition. The initial panoramic radiograph demonstrated a large periapical pathology area associated with the first premolar. Eventually, both the canine and first premolar teeth were retreated, although the paresthesia did not resolve for approximately four months. A brief review of endodontic-associated paresthesia is provided, along with a description of the therapy and postoperative radiographs taken 20 months later.
