Introduction: A separated instrument in a root canal system has the potential of severely affecting the outcome of endodontic therapy. This study evaluated the effectiveness of the minimally invasive GentleWave System (Sonendo Inc, Laguna Hills, CA) in removing separated stainless steel endodontic files from the apical and midroot regions of molar root canals.
Methods: Thirty-six extracted human molars were accessed, and the glide path was confirmed to the apex.
