Rarely, this nerve injury can occur before, during or after endodontic treatment. Endodontics-related causes of paresthesia are periapical infections, local anesthesia, chemical and mechanical irritations that occurs during root canal irrigation, shaping and filling procedures. Endodontic-related paresthesia is mostly seen in lower molar teeth and surgical treatment approach is followed. This case report aimed to present diagnosis and non-surgical treatment of mental nerve paresthesia caused by gutta-percha overextension from the apex of right second premolar with the usage of cone-beam computed tomography (CBCT). Case: 40-year-old woman had pain and numbness in her right lower lip and chin which occured two days later following endodontic therapy for her mandibular right second premolar. The gutta-percha was removed from the root canal in one piece and the patient’s complaints were gone. One-year follow-up was uneventful. Conclusion: CBCT can be considered as an effective diagnostic tool when inferior alveolar nerve paraesthesia due to endodontic treatment complication is suspected. Non-surgical retreatment procedures could be beneficial in cases of paraesthesia caused by gutta-percha extrusion.}, number={2}, publisher={Zonguldak Bülent Ecevit Üniversitesi}, organization={yok}
