A Comparative Evaluation of two engine driven Nickel-Titanium files used in different kinematics (An in vitro study)

Abstract

Endodontic treatment aims primarily to retain the remaining tooth after being affected by decay or trauma in order to ensure the preserved structure and subsequent restoration are both functionally and esthetically surviving for the longest period of time in the oral cavity. One of the main steps in achieving successful endodontic treatment is mechanical preparation of the root canal. This has to be done to achieve proper debridement of the root canal without changing the original shape of the root canal. Aberrant root canal anatomies makes proper debridement difficult and might lead to unwanted adverse events such as generation of excessive root surface strain, canal transportation, dentine microcracks with subsequent root fractures.
