“…1,3,6,8 Orthograde retrieval is a time consuming and often a difficult procedure. Many orthograde techniques such as grasping with hemostats, a tube and Hedstrom file, wire loops, and devices such as the Masserann Kit, Instrument Removal System (IRS), Endo Extractor, Endo Safety System, and ultrasonics have been described for fragment retrieval.…”

Instrument fracture is a procedural mishap that prevents efficient cleaning and shaping of the root canal. When bypassing the fracture fails, the fragment must be removed. Many techniques and devices have been described to remove fragments from the root canal. The Masserann Kit is a widely used instrument for the removal of fragments. These clinical cases describe use of the Masserann Kit to remove separated instruments blocking the entire canal in posterior teeth.

“…The use of the operating microscope as adjunct to these procedures increases the chances of intracanal instrument removal (10,11). However, unsuccessful attempts at removal of a fragment can affect the root dentin integrity, especially in the apical third of the canal (3,9,10).…”

Obturation Over an S1 ProTaper Instrument Fragment in a Mandibular Molar with Three Years of Follow-up

et al. 2014

This paper describes root canal filling performed over a large S1 ProTaper file fragment in a second mandibular molar with irreversible pulpitis. An S1 ProTaper file was fractured during the instrumentation of the mesiobuccal canal. Approximately 10 mm of file fragment remained in the apical and middle thirds of the canal. The obturation was performed over this fragment using thermomechanically compacted gutta-percha and sealer. Radiographic findings and the absence of clinical signs and symptoms at 3-year follow up indicated successful treatment. Cone-beam computed tomography images revealed absence of periapical lesion and details of intracanal file fragment related to root fillings and apex morphology. In this case, the presence of a large intracanal fractured instrument did not have a negative impact on the endodontic prognosis during the follow up evaluation period.

Objective: To evaluate the prevalence of dentin defects, including partial and complete cracks and fractures, after root canal preparation in molars with Reciproc and WaveOne reciprocating instruments. Material and Methods: Fifty mandibular first and second molars with mature apices were selected to endodontic in vitro instrumentation. Ten teeth were unprepared and served as the control, and the remaining forty teeth were divided into two groups, being twenty corresponding to each reciprocating system. Reciproc and WaveOne systems were used in a reciprocating working motion, under the same conditions, to prepare the two mesial canals. Roots were then sectioned 2, 4 and 6 mm from the apex, and the cut surface was observed under a microscope using 20-fold magnification and checked for the presence of fractures and incomplete cracks. Results: none of the evaluated groups presented fractures, and the control group showed no incomplete cracks. Overall evaluation showed statistical differences between these two groups and the control group (p=0.017) for the prevalence of incomplete cracks, but no significant differences were obtained between Reciproc and WaveOne groups (p>0.05). Reciproc group presented more incomplete cracks on 4-mm sections compared with the control group on the same section (p=0.0326). Conclusion: Root canal preparation with both reciprocating instruments resulted in incomplete cracks, but not fractures. At the level of 4 mm from the apex of the canals, the Reciproc system produced significantly more incomplete cracks. Considering both systems, WaveOne utilization resulted in lesser structural alterations on dentin considering the middle portion of the roots.
