Abstract: Separation of endodontic instruments within the root canal is one of the common complications during root canal preparation. Management of separated instruments includes orthograde approaches, surgical approaches and extraction. It is essential to evaluate the conditions of specific cases in order to choose the proper approach. Based on the review of literatures and clinical experiences in dealing with broken instruments, the present article proposes the evaluation methods and management options, especially emphasizing the removal strategies, which may help dentists in treating the separated instrument cases.

Key words: broken instrument, evaluation, removal, dentin thickness, broken instrument, evaluation, removal, dentin thickness
