The purpose of this paper is to provide useful information that will enable dentists to predictably shape root canals for three-dimensional obturation of the root canal system. The information is intended to help clinicians better understand when and how to safely use Nickel-Titanium (NiTi) rotary shaping instruments. This article is intended to enhance clinical performance for all dentists who...

Background and Objective: The preparation of the root canal (i.e., cleaning and shaping) is the main step in the endodontic treatment. The nickel-titanium rotary files result in fewer errors during the preparation of curved canals. This study aimed to compare the transportation of Neolix and Reciproc rotary systems in curved canals using cone beam computed tomography (CBCT). Materials and Meth...

Background and Aims: Cleaning and shaping is one of the most important stages in endodontic treatment. Single-file systems save time and reduce the risk of transmission of pathogens. This in vitro study was aimed to compare the rate of canal transportation after the preparation of the stimulated resin root canal with two single-file systems, namely Waveone and Reciproc. Materials and Met...

BACKGROUND With root canal treatment, the organic debris and micro-organisms from pulp space is removed and an ideal canal preparation is achieved that is conducive of hermetic obturation. The purpose of this study was to correlate the pre-operative canal curvature with the postoperative curvature in human extracted teeth prepared with K-3 rotary systems. METHODS The root canal preparation wa...
