Non-surgical management of paresthesia induced by calcium hydroxide extrusion - a case report with a 4-year follow-up

Abstract

The present case report describes the non-surgical treatment of alveolar inferior nerve paresthesia caused by the extrusion of calcium hydroxide as intracanal medicament. A 45-year-old female patient had a chief complaint of numbness and pain in the left lower lip region for 2 months. Radiographic examination revealed calcium hydroxide overflow into the mandibular canal. Irrigation of the root canal system with saline using a 27-gauge needle was done to remove as much calcium hydroxide as possible but proved ineffective in removing material from the outside tissues. Root canal treatment was completed in 1 week, and non-surgical paresthesia treatment with steroids and pregabalin was done for one month. In the 1-year follow-up control, the paresthesia had reduced significantly. In a 4-year follow-up visit, there was a complete resolution of paresthesia, and the radiographic analysis showed that calcium hydroxide was completely resorbed.
