Retrieval of a separated file using Masserann technique: a case report

Area of Science:

• Endodontics
• Dental Materials Science

Background:

• Separated instruments, such as broken files, create metallic obstructions in root canals, hindering effective cleaning and shaping.
• Bypassing these fragments is often unsuccessful, necessitating mechanical retrieval methods.

Observation:

• This clinical case focuses on the retrieval of a separated file lodged in the apical third of a maxillary left lateral incisor's root canal.
• The file acted as a tight metallic obstruction, preventing standard endodontic procedures.

Findings:

• The Masserann Kit, a mechanical device designed for orthograde removal of intracanal metallic obstructions, was employed.
• Successful retrieval of the separated file was achieved using the Masserann technique.

Implications:

• The Masserann technique offers a viable solution for managing separated instruments in the apical third of root canals.
• Effective retrieval of obstructions restores the possibility of thorough root canal cleaning and shaping, improving treatment outcomes.
