Retrieval of an Unusual Foreign Object from the Root Canal: A Case Report

The success of root canal therapy depends on thorough debridement, microbial control, and complete sealing of the canal system. Prolonged exposure of canals, often left open for drainage, may predispose them to the lodgment of foreign objects, serving as a nidus for reinfection. This report describes a 28-year-old male who presented with pain and pus discharge from the right maxillary lateral incisor. Six months earlier, he had undergone incomplete root canal treatment, leaving the canal open. Clinical examination revealed discoloration and an open pulp chamber, while radiographs showed a radio-opaque object within the canal. The object was retrieved using endodontic files and tweezers, and identified as a corroded sewing needle. The canal was cleaned, shaped, and obturated, and the tooth remained functional and asymptomatic at a one-year follow-up. This case underscores that foreign body lodgment in open canals is a preventable complication. Avoiding prolonged canal exposure, ensuring patient compliance, and employing careful retrieval techniques are essential for successful outcome.
