Resolution of paresthesia following non-surgical endodontic treatment of periapical lesions associated with the inferior alveolar and mental nerves: A case series

Paresthesia is a condition characterized by reduced sensitivity due to sensory nerve damage, often associated with dental procedures and infections. This case series aims to evaluate the recovery of patients experiencing paresthesia following nonsurgical endodontic treatment of periapical lesions closely associated with the inferior alveolar and mental nerves. Three cases of paresthesia were presented, each involving the mandibular region. The patients underwent thorough clinical and radiographic evaluations, including panoramic, periapical radiographs and cone beam computed tomography (CBCT). Nonsurgical endodontic treatments were performed to the related teeth. During treatment procedures, calcium hydroxide was used for intracanal dressing. Root canals were filled with gutta-percha and a root canal sealer. Follow-up visits were conducted at 6-months and 1-year to monitor the resolution of paresthesia and healing of periapical lesions. In all cases, complete recovery from paresthesia was noted during clinical assessments, and radiographic follow-ups at 6 month and 1-year demonstrated significant healing of the periapical lesions. Nonsurgical endodontic treatment is effective in treating paresthesia caused by periapical lesions associated with the inferior alveolar and mental nerves. Early intervention and precise endodontic treatment can lead to complete recovery from paresthesia, as demonstrated in these cases.
