Retrieval of a separated instrument using Masserann technique.

Thirumalai AK, Sekar M, Mylswamy S - J Conserv Dent (2008)

Bottom Line: The fracture of endodontic instruments is a procedural problem creating a major obstacle to normal routine therapy.When an attempt to bypass such a fragment becomes difficult, it should be retrieved by mechanical devices.These clinical cases demonstrate the usage of Masserann technique in removal of separated instruments in anterior and also the posterior teeth.

ABSTRACT
The fracture of endodontic instruments is a procedural problem creating a major obstacle to normal routine therapy. The separated instrument, particularly a broken file, leads to metallic obstruction in the root canal and impedes efficient cleaning and shaping. When an attempt to bypass such a fragment becomes difficult, it should be retrieved by mechanical devices. Masserann kit is one such device for orthograde removal of intracanal metallic obstructions. These clinical cases demonstrate the usage of Masserann technique in removal of separated instruments in anterior and also the posterior teeth.

Figure 0005: (a) – Radiograph showing the separated file in the distolingual canal; (b) – Extractor with plunger sleeving and gripping the fragment; (c) – Post-obturation 36, 37

Mentions: Access opening was done under rubber dam in 36, 37. Four canals were located in 36, 37. Working length was determined. During cleaning and shaping, a #25 stainless steel K-file was separated in distolingual canal in 36. A radiograph was taken to confirm the level of separation of the instrument [Figure 5a]. The instrument was found to be separated at the junction of coronal and middle third of the root canal. Masserann technique was used for retrieval of the instrument [Figure 5b]; and after several attempts, the instrument was retrieved successfully.
