Sewing Needle Obturation of Root Canal: A Rare Case Report.

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.

Surgical endodontic management of infected lateral canals of maxillary incisors

This case report presents surgical endodontic management outcomes of maxillary incisors that were infected via the lateral canals. Two cases are presented in which endodontically-treated maxillary central incisors had sustained lateral canal infections. A surgical endodontic treatment was performed on both teeth. Flap elevation revealed vertical bone destruction along the root surface and infected lateral canals, and microscopy revealed that the lateral canals were the origin of the lesions. After the infected lateral canals were surgically managed, both teeth were asymptomatic and labial fistulas were resolved. There were no clinical or radiographic signs of surgical endodontic management failure at follow-up visits. This case report highlights the clinical significance and surgical endodontic management of infected lateral canal of maxillary incisor. It is important to be aware of root canal anatomy variability in maxillary incisors. Maxillary central incisors infected via the lateral canal can be successfully managed by surgical endodontic treatment.

Non- Surgical Endodontic Management of The Combined Endo- Perio Lesion: Report of Three Case.

Endodontic–periodontal lesions offer a constant challenge to the clinician for diagnosis, treatment and prognosis of the teeth that are of great concern. Treatment and prognosis of endodontic–periodontal diseases vary depending on the cause and the correct diagnosis of each specific condition. This article presents successful healing of combined endo-perio lesions after non-surgical endodontic management with long term follow up.
