This study compared the shaping ability of five Ni-Ti rotary files (ProTaper Universal, Reciproc, Hyflex CM, ProTaper Next and TF Adaptive) in simulated root canals. Each group consisted of 10 root canals. Preand post-instrumentation photographs were taken using a precise camera and superimposed with Photoshop. Material removal from the inner and outer canal walls, transportation and centering ...

INTRODUCTION This clinical study was conducted to compare the effectiveness of single-file reciprocating systems and rotary systems in removing endotoxins and cultivable bacteria from primarily infected root canals. METHODS Forty-eight primarily infected root canals were selected and randomly divided into 4 groups: WaveOne (Dentsply Maillefer, Ballaigues, Switzerland) (n = 12); Reciproc (VDW,...

Background. The present study aimed to compare the shaping ability of Reciproc Blue instruments with or without the creation of a glide path in simulated S-shaped root canals. Methods. Root canals of thirty #15.02 clear resin S-shaped blocks were dyed using ink and photographed. Then the blocks were randomly divided into 2 groups: group A: Reciproc Blue with glide path created with ProGlider an...

Aim:To compare the incidence of dentinal defects after preparation with reciprocating (Reciproc and WaveOne) and fullsequence rotary ProTaper Universal and Protaper Next instruments. Materials and methods:One hundred human mandibular premolars were randomly assigned to 5 groups (n = 20 teeth per group). The root canals were instrumented by using the reciprocating single-file systems Reciproc an...

Aim: To evaluate the cyclic fatigue resistance of Pro Taper NEXT & Reciproc R rotary files in simulated canals with angle curvaturesat 45o and 60 o.Materials Methods; This study was conducted at HKE' s S.Nijalingappa institute dental sciences reasearch institute,Kalaburagi. After considering inclusion exclusion criteria selected samples were divided into two groups, as G1(ProTaperNEXT) G2(R...

Introduction: Root canal instrumentation is an important phase in root canal therapy. Since success in endodontic treatment depends on file defect and fracture, the aim of this study was to compare the evaluation of defect and fracture in rotary and reciproc files in severe curved root canals. Materials & Methods: In this experimental study, 60 mesial canals of human closed apex molars with ...

Abstract Background The purpose of this study was to evaluate the changes in canal volume after root preparation vivo with 3 different single-file techniques (Reciproc-Blue®, WaveOne-Gold® and XP-EndoShaper®), a new method using CBCT 3D reconstruction. Methods In prospective study, thirty human lower premolars from healthy patients were used, which extraction indicated for orthodontic reasons. ...

INTRODUCTION The aim of this study was to evaluate the resistance to flexural fatigue of Reciproc R25 (VDW, Munich, Germany), WaveOne Primary (VDW, Munich, Germany), Mtwo (Sweden & Martina, Padova, Italy), and Twisted File (TF; SybronEndo, Orange, CA) instruments used in continuous rotation or in 2 different reciprocating motions. METHODS A total of 180 nickel-titanium files from 4 brands mar...

Objective To evaluate transportation (T) and centering ability (CA) of root canal preparations using continuous or reciprocating nickel-titanium endodontic files. Materials and Methods Ninety-six mesiobuccal root canals of mandibular first and second molars were randomly divided into 6 groups (n=16) according to the rotary file used: 1. ProTaper Next; 2. ProTaper Gold; 3. Mtwo; 4. BioRaCe; 5....

AIM The aim of this in vitro study was to assess the amount of apically extruded debris and irrigant using Reciproc vs self-adjusting fle (SAF) and to investigate the effect, if any, of gravitational force via mandibular and maxillary positioning of the teeth. MATERIALS AND METHODS Forty human mandibular premolars were randomly assigned to four groups of 10 teeth each. The root canals were in...
