Introduction Endodontic instruments are developed to provide a better cleaning of the root canal system and reduce its risk of fracture. The aim of this study was to evaluate the instrumentation time and cyclic fatigue resistance of WaveOne Gold, ProDesign R and ProDesign Logic files. Methods and Materials Thirty Nickel-titanium (NiTi) rotary instruments were divided into 3 groups (n=10). Pro...

Objectives It was aimed to compare the cyclic fatigue resistances of ProGlider (PG), One G (OG), and HyFlex EDM (HEDM) nickel titanium glide path files in single- and double-curved artificial canals. Materials and Methods 40 PG (16/0.02), 40 OG (14/0.03), and 40 HEDM (10/0.05) single-file glide path files were used in the present study. Sixty files were subjected to cyclic fatigue test by usi...

BACKGROUND Reciproc instruments are the only contemporary root canal instruments where glide path preparation is no longer strictly demanded by the manufacturer. As the complete preparation of root canals is associated with success in endodontic treatment we wanted to assess the ability and find predictors for Reciproc instruments to reach full working length (RFWL) in root canals of maxillary ...

Fidel RAS. The ability of the Reciproc R25 instrument to reach the full root canal working length without a glide path.

OBJECTIVES Glide path preparation is recommended to reduce torsional failure of nickel-titanium (NiTi) rotary instruments and to prevent root canal transportation. This study evaluated whether the repetitive insertions of G-files to the working length maintain the apical size as well as provide sufficient lumen as a glide path for subsequent instrumentation. MATERIALS AND METHODS The G-file s...

conclusions the incidence and severity of sore throat and hoarseness after tracheal intubation by glide scope were lower than in the macintosh laryngoscope. the incidence and severity of sore throat were increased by intubation and longer operation times. patients and methods three hundred patients were randomly allocated into two groups of 150: macintosh blade laryngoscope or glide scope video...

Background: Training of airway management and tracheal intubation skill in emergencies for resuscitation of patients are basic skills for medical students. However, the success rate of beginners in this skill is low. Video laryngoscopes are new devices that can increase the success of endotracheal intubation training. Methods: This clinical trial was conducted with 30 medical students who came...
