Modern rotary files in minimally invasive endodontics: a case report.

Modern Endodontics aims to remove or decrease the bacterial load within the endodontic space. This target is achieved by performing adequate mechanical preparation combined with three-dimensional cleaning. The first step, shaping, is done using manual stainless steel files and Ni-Ti rotating files. In recent years, new rotating files have been developed in the martensitic phase, which, being more flexible, guarantees to work safely in the case of difficult anatomies. Therefore, this study aimed to demonstrate a non-surgical endodontic treatment using modern Ni-Ti files in a minimally invasive approach.
