There have been significant advancements in the development of NiTi rotary instruments in recent years. This evolution is driven by market demand and the continuous improvement in the manufacturing process. Dentists have increasingly identified the features they deem essential on the endless journey towards a more perfect file. These features include flexibility, efficiency, safety, and simplic...

use of rotary nickel-titanium (niti) instruments for endodontic preparation has introduced a new era in endodontic practice, but this issue has undergone dramatic modifications in order to achieve improved shaping abilities. cone-beam computed tomography (cbct) has made it possible to accurately evaluate geometrical changes following canal preparation. this study was carried out to compare cana...

BACKGROUND Many new rotary files systems have been introduced, however, limited research has been conducted related to the surface irregularities of these files and if these have any effects on the files themselves. Hence, the aim of the present study was to analyze surface irregularities of the ProTaper® Universal rotary files (PTU) and the ProTaper Next™ rotary files (PTN) before and after in...

IJMDS ● www.ijmds.org ● January 2015; 4(1) 701 Review Article Single file niti-rotary systems Kumar SR, Gade V ABSTRACT The cleaning and shaping of root canals is a major step in root canal treatment procedure, which aims at removal of all the tissue debris from the root canal space while removing the inner layers of root canal dentin. With Nickel titanium (NiTi) rotary instruments this goal is...

OBJECTIVE The aim of this study was to evaluate the biomechanical preparation of flattened root canals using the following systems: Endo-Eze AET stainless steel oscillatory instruments (Ultradent) and RaCe rotary NiTi instruments (FKG Dentaire). MATERIAL AND METHODS Twenty extracted human mandibular incisors were randomly assigned to two groups: Group 1 - Instrumentation with oscillatory Endo...

Objective:
 To assess the life of two different rotary nickel-titanium (NiTi) instruments in curved canals with complete protocol, by using 360°rotation motion and reciprocating motion.
 Materials Methods:
 About one hundred seventy extracted maxillary mandibular molars were taken from which root selected randomly divided 2 groups, for analyzing number uses files. One prepared Hy...

The aim of this study was to analyze the effect taper and apical diameter nickel–titanium (NiTi) endodontic rotary files on dynamic cyclic fatigue resistance. A total 50 unused conventional NiTi wire alloy instruments were used in study. All submitted a custom-made device until fracture occurred. time failure, number cycles pecking movements, length fractured file tip analyzed using analysis va...

Achieving apical foramen patency through surgical maneuvers during the biomechanical preparation of root canals is a goal sought by several schools. The aim of this study was to evaluate the deformation of the foramen as a result of using stainless steel hand files and nickeltitanium rotary instruments for achieving patency. Forty recently extracted dental roots with single canals were calibrat...
