ABSTRACT
Discovery of a foreign object in the root canal is unusual and rare. Forceful lodgement or impaction of the foreign object in the pulp chamber or root canal is usually accidental. It is seen more often among children with habits of chewing and placing various objects in the oral cavity. Despite new advances and a large understanding about the root canal morphology, retrieval of foreign objects from the root canal is still a challenging procedure to the endodontists. Exposed pulp chamber due to trauma or tooth left open for drainage after root canal access opening are predisposing factors to foreign body lodgement. The impacted foreign objects in root canals may act as a source in causation of discomfort, pain, infection, and swelling. An attempt to retrieve any foreign body from the root canal may increase the chances of its further apical displacement and firm lodgement in the apical third of the root invariably risking the prognosis of the tooth involved. The present case report describes an inadvertently broken sewing needle in the root canal of the permanent maxillary left central incisor with periapical abscess and its successful retrieval by non-surgical orthograde endodontic treatment.
