Rotary technology

Rotary endodontic files use an engine to rotate the endodontic file during root canal treatment. The advantages of rotary endodontics are reduced instrumentation times and fewer files used during the procedure. Commonly Nickel-Titanium files are used because of their greater flexibility which permits increasingly curved roots to be treated. The use of Ni-ti files comes at a cost of at increased risk of fractured endodontic files, possibly necessitating endodontic retreatment.
