Patient induced unusual metallic obturation of the root canal of permanent maxillary central incisor with an immature apex – A rare case report

Discovery of multiple foreign objects in the root canal is unusual and their removal is often difficult and challenging procedure. Entrapment of the foreign object in the pulp chamber or in root canal usually occur accidentally in children with the habit of chewing or placing various objects in the oral cavity. Clinically it was often encountered in tooth with wide carious lesion, exposed pulp chamber due to trauma or tooth left open for the drainage during root canal treatment. This impacted foreign body may act as a potential source of pain or infection. The attempt to retrieve such foreign object from the root canal with immature apex increases the risk of its displacement into periapical area. The present case report describes an unusual case of a patient with two metallic sewing needles inadvertently broken down in the root canal of the permanent maxillary left central incisor and it׳s successful retrieval by non-surgical endodontic treatment.
