Continuous Instrumentation and Irrigation: The Self-Adjusting File (SAF) System

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

The recently introduced self-adjusting file (SAF) system is the first of its kind, performing continuous and simultaneous instrumentation and irrigation. As an instrumentation device it adapts itself to the shape of the canal, including its cross section, as opposed to most rotary file systems that machine the canal to the shape of the file. The SAF system removes a uniform dentin layer from all around the canal as opposed to rotary files which are using excessive removal of sound dentin in attempt to include the whole canal within the preparation. Combined with its effective irrigation, it allows a new concept of minimally invasive endodontics. The SAF system is a no-pressure irrigation system combined with an added mechanical scrubbing effect. The effective cleaning of oval canals enables more effective disinfection and better obturation than can be achieved with rotary files. Its scrubbing effect is also useful in the final stage of retreatment as well as in the treatment of root canals of immature teeth.
