Bypass of two Broken Instruments in a Severly Curved Canal: a Case Report

Objectives: The curved root canals often pose challenges in their endodontic management. Instrument breakage is a common mishape which management options gets reduced in a curved canal especially when visual access is restricted. Bypassing the fractured instrument represents the most conservative way to deal with the obstacle without compromising the desinfection of the root canal.
Objectives Describe the management of 2 broken files in a severly curved canal by the bypass technique
Methods: A 35 years old female patient visited the dental service of Sahloul to pursue her endodontic treatement. The patient had asymptomatic periodontitis on tooth 15. On the pre-operative periapical radiograph, 2 broken instruments were visible in the curvature of the palatal canal. The curvature was considered severe as the angle of curvature was estimated around 80° with shneider’s method. Gaining a straight line access until the beggining of the curveture and using precurved small hand files and martensitic Niti files were very helpful to overcome these difficulties.
Results: Bypass of both broken instruments and root canal obturation were successfully performed and the patient was referred for a prosthetic rehabilitation.
Conclusions: A clinician is required to have a meticulous study of the pre-operative radiography to determine the degree of curvature of the canal and to assess the lengh, the position and the type of the fractured instrument. Case difficulty planning and strategizing is of critical importance to define the proper flexible instruments and to employ safe techniques of instrumentation that achieves the biologic and mechanical aspects of endodontic therapy.
