Retrieval of separated instruments using a combined method with a modified vista dental tip

Biomechanical preparation of the entire root canal system is one of the most important procedures in endodontic treatment. Separation of instruments while preparing root canals presents a compromised situation in which a biologically inert segment is left behind with potential contamination that has the ability to affect the healing process. Management of this procedural error is tedious and requires creativity as well as clinical knowledge and skills. In this report, we demonstrated two cases with separated instrument in which a combined technique of ultrasonic method with microtube tube method was used to retrieve the separated tips using a modified Vista dental tip
