“…The use of this single instrument allows its adaptation inside the root canal, and by its vibratory movement (3000 to 5000 vibrations per minute) of low amplitude (0.4 mm), it promotes uniform dentine wear, which results in a canal with a cross section similar to the original but with slightly larger dimensions. 2,29,30,31,32,33,34,35 Several reciprocating systems have been released 26 such as Waveone (Dentsply Maillefer, Baillagues, Switzerland) and Reciproc (VDW GmbH, Munich, Germany), which are based on the concept of root canal preparation with a single instrument. These instruments are manufactured with a M-Wire alloy from a thermal treating process of the NiTi alloy, which provides greater flexibility and resistance to cyclic fatigue than the conventional NiTi alloy.…”

“…These instruments are manufactured with a M-Wire alloy from a thermal treating process of the NiTi alloy, which provides greater flexibility and resistance to cyclic fatigue than the conventional NiTi alloy. 4,9,11,13,15,33,34,35,36,37,38,39,40,41,42,43,44,45 The movement dynamics of these instruments, known as reciprocating, is the rotation in the counterclockwise direction (cutting direction) followed by a less extensive clockwise rotation (instrument releasing direction), facilitating continuous and progressive movement toward apical. 15,26 According to some authors, the reciprocating movement reduces the risk of torsion fracture because the instrument is not subjected to the stress levels caused by a continuous rotary motion.…”

“…This results in improvement of the flexibility along the active part of the instrument and minimizes the instrument locking in the dentin, in addition to reducing the formation of debris. 8,30,34,41,59 These features were incorporated into additional systems including Protaper Next (Dentsply Maillefer, Ballaigues, Switzerland), TRUShape (Dentsply Tulsa Dental Specialties, Tulsa, USA), Revo-S (Micro-Mega, Besançon, France), and One Shape (Micro-Mega, Besançon, France).…”

“…27,76,77,78 The development of micro-CT allows a more precise RCS evaluation than a conventional CT scanner, and more recent use of specific software has made it possible to accurately assess the biomechanical preparation as well as the anatomy, root canal filling, and retreatment. 2,3,4,5,7,9,11,12,13,14,15,25,27,28,29,30,31,34,35,37,38,39,40,41,42,43,44,45,47,56,57,58,59,61,62,63,68,79,80,81,82,83,84,85,86,87,88,…”

Root canal preparation using micro-computed tomography analysis: a literature review

et al. 2018

View full text Add to dashboard Cite

This literature review has critically analyzed the published research related to the biomechanical preparation of root canals with three-dimensional analysis using micro-computed tomography (micro-CT). In December 2017, six databases (PubMed, Cochrane, Web of Science, Embase, Scopus, and Science Direct) were accessed using keywords to find articles including the use of the micro-CT analysis in biomechanical root canal preparation. There were 60 full articles that were selected, which were screened and read by two authors. The research that was reviewed and analyzed included root canal anatomy and sample selection, changes in canal shape and untouched canal areas, canal transportation and centering ability, and kinematics (motion). Of the studies selected, 49.18% discussed anatomical characteristics, with 54.1% of these studies describing mesial roots of mandibular molars with moderate curvature. Only 35% used a stratified distribution based on root canal system morphology and quantitative data obtained by micro-CT. The analysis of canal transportation and centering ability showed that transport values in the apical third exceeded the critical limit of 0.3 mm in mesial roots of mandibular molars with moderate curvature, especially in the groups in which a reciprocating system was used. In relation to kinematics, 91.70% of the reviewed studies evaluated continuous rotating instruments, followed by reciprocating rotation (38.33%), vibratory (15%), and the adaptive kinematics, which was in only 8.33%. The reciprocating kinematics was associated with higher canal decentralization and transportation indexes, as well as a greater capacity for dentin removal and debris accumulation. This literature review showed that the anatomy, the type of design and kinematics of instruments, and the experimental design are factors that directly influence the quality of biomechanical preparation of root canals analyzed in a qualitative and quantitative manner by micro-CT.

“…Finally, Reciproc® (0.801±0.140mm2) and Neoniti® (0.805 ± 0.081 mm2) were significantly better overall. Ahmetoglu et al ( 38 ) compared Reciproc®, Revo-S® and Self-Adjusting File® (SAF) by micro-computed tomography (μ-CT) in maxillary first molars, and found no significant differences between instrumentation systems (P>0.05). In another study, Saleh et al ( 39 ) investigated Reciproc®, Wave One®, One Shape® and F360® 25 files using resin blocks and superimposing preoperative and postoperative images.…”

ObjectiveThe aim of this study was to compare the cutting are, root canal anatomy preservation and non-instrumented areas of F360®, F6-SkyTaper®, Hyflex-EDM®, iRACE®, Neoniti®, O.Shape®, P.Next®, Reciproc®, Revo-S® and Wave-One-Gold® size 25 files.Materials and Methods300 teeth with a single straight root and a circular or elliptical root canal were divided into 10 groups (1-F360®, 2- F6-SkyTaper®, 3-Hyflex-EDM®, 4-iRACE®, 5-Neoniti®, 6-O.Shape®, 7-P.Next®, 8-Reciproc®, 9-Revo-S® and 10-Wave-One-Gold®) cut into 3 cross sections using an ultrafine cutting disc. They were photographed under a stereo microscope and preinstrumentation analyses were made before rebuilding the teeth with# 10 K- File and epoxy glue. A glide path was created with #10 and #15 K files and each group was instrumented using rotary or reciprocating systems. Cutting areas, root canal anatomy preservation and non-instrumented areas were analyzed using the AutoCAD 2015 Levene's test, the Welch´s test, and the Games-Howell´s test. The Pearson’s chi-squared test was used for statistical analysis.ResultsLevene's test showed no equality of variances (P<0.05), therefore Welch´s and Games-Howell's tests were applied to cutting areas, showing significant differences in all thirds and overall (P<0.05). No differences in root canal anatomy preservation were observed (P>0.05). In non-instrumented areas, significant differences were found (P<0.05) in middle third being better in Reciproc®, Neoniti® and WaveOneGold®, and in apical thirds being higher P.Next®, Reciproc®, HyflexEDM®, Neoniti® and WaveOneGold®.ConclusionsIn cutting area, P.Next® and Reciproc® were superior in coronal third, Neoniti® and Hyflex EDM® medially and apically and Neoniti® and Reciproc® overall. Regarding the root canal anatomy preservation, all systems were similar. For non-instrumented areas, all systems achieved similar results coronally, but Reciproc®, Neoniti® and Wave One Gold® were superior in middle third and P.Next®, Reciproc®, Hyflex EDM®, Neoniti® and Wave One Gold® were superior in apically.
