Thermafil removal - theory

How to remove a Thermafil

Overview

This video explores the challenges associated with endodontic retreatment when a tooth has been previously obturated with Thermafil. The video outlines the process of managing the plastic carrier coated with GP, in order to create the space to facilitate cleaning.

Key topics covered

• Challenges associated with Thermafil: Risk of GP stripping back during insertion, presence of the plastic carrier
• Instrument selection for Thermafil removal: Hand files (C-Pilot, Size 10, 12), Hedstroem files (Size 20 & 25), Reciproc (M-Wire & Blue) instruments
• Techniques: Using solvents (eucalyptus oil, chloroform), hand file and Hedstroem braiding, Reciproc instrumentation
• Technique focus: Reciproc instrumentation
