Instrument fracture is one of the most common procedural endodontic mishap during root canal therapy resulting in inadequate cleaning and shaping of root canals. Inadequate biomechanical preparation affects the outcome and prognosis of root canal treatment. Therefore retrieval of the separated instrument should be considered. When an attempt to bypass such a fragment becomes difficult, it should be retrieved by mechanical devices. Various instrument retrieval kits and techniques are available for this purpose. In the present case series report the separated rotary instruments were successfully retrieved from the MB canal of mandibular right and left molars using Masserann kit and ultrasonic tips and from maxillary central incisors with H file manually.
