ABSTRACT
Background: Procedural mishaps can occur during any step of root canal during cleaning and shaping, and might affect the prognosis of treatment. Among these separation of instruments in the canal is one of the most troublesome incidents in endodontic therapy especially if the fragments cannot be removed. Several techniques have been employed to facilitate the removal of the fragments; however, they are technique sensitive, expensive and require great expertise.
Aim: This paper aims to suggest combination of techniques for retrieval of file from apical or beyond the apical third of canal.
Materials and Methods: A 30year old patient presented with pain in upper anterior tooth. Clinical examination revealed a temporary restoration in 21 with no soft tissue abnormality. A radio-visio-graph indicated 22 associated with periapical radiolucency and a separated file extending 3mm beyond the radiographic apex in the periapical area. Retrieval of the separated instrument was planned using braiding technique followed by obturation and post endo restoration.
Second case report includes a female 43 years old with pain in upper lateral incisor. IOPA radiograph revealed a separated instrument in the apical third of root canal. Retreatment was planned by first bypassing the fractured file and then using ultrasonics to loosen the fragment followed by obturation and post endodontic restoration.
Conclusion: Combining different techniques during file retrieval can retrieve file with minimal dentinal destruction.
