Endodontic management of thin and double-curved root of maxillary lateral incisor

Abstract

The present case report discusses the endodontic management of maxillary lateral incisor with very thin and double-curved root, also known as bayonet-shaped root. A young healthy male patient presented with acute pain in the left maxillary incisor. Clinical examination and radiographic analysis confirmed the diagnosis of previously treated pulp and symptomatic apical periodontitis. Endodontic treatment was carried out with hand and rotary instruments, and the canal was filled using lateral compaction technique. Six-month radiographic follow-up showed good signs of periapical healing. Technique to prepare and obturate such thin and double-curved root requires preoperative measurement of canal curvature angles with creation of glide path to the apex to maintain the taper of the canal and to avoid mishaps.
