A case of separated instrument in the apical region of a severely curved root canal using ultrasonic method
Abstract：Instrument separation within the root canal is one of the common complications of root canal treatment. It cannot be completely avoided under the current economic and technical conditions [1]. It may lead to failure of root canal treatment, cause medical disputes, and is a major concern for clinical physicians [1]. Studies show that most instruments are separated in the curved part or the area beyond the curve of severely curved root canals, accounting for 60% to 90% of the total incidence of instrument separation [2-5].
