“…Also, TruNatomy produced less volume changes when compared to XP-Shaper, WaveOne Gold, Reciproc Blue, TRUShape and iRace [19,20]. Although, similar volume changes were observed when TruNatomy was compared to Vortex Blue, Edge le X3 and ProTaper Next [5,20,24]. Vortex Blue was found to have the same canal volume changes when compared to TRUShape, ProTaper Next and ProTaper Universal, but less volume changes when compared to XP-Shaper in oval canals [21,22,25].…”

“…The changes in root canal surface area and canal volume after preparation with both VB and TN groups were similar with no signi cant differences. TruNatomy showed no signi cant differences in the changes in canal area after instrumentation when compared to Vortex Blue, ProTaper Next, XP-Shaper [5,19,24]. Although signi cantly less changes in canal surface area were observed when TruNatomy was compared to WaveOne Gold, Reciproc Blue, TRUShape and iRace [19].…”

Aim: To assess and evaluate the canal shaping ability of two different Ni-Ti rotary systems ex-vivo: Vortex Blue (VB) and TruNatomy (TN), using micro-computed tomography (micro-CT) in extracted premolar human teeth. Materials and Methods: A total of 20 extracted bifurcated maxillary first premolars with two separate buccal and palatal canals wererandomly divided into two groups and prepared with either Vortex Blue or TruNatomy files. All teeth were scanned by micro-CT before and after root canal preparations. The micro-CT scans were analyzed to measure the following parameters: percentage of untouched canal surface area, changes in canal surface area, changes in canal volume, structural model index (SMI), changes in canal angulation and changes in dentin thickness. Statistical analysis was conducted to compare the means and standard deviations of the parameters between the two systems, with statistical significance level set at P-value < 0.05. Results: Both VB and TN files exhibited a significant increase in the basic canal geometry parameters including canal surface area and canal volume after canal instrumentation with no statistical significant differences between both files and with no considerable shaping mishaps or errors. Both file systems showed no significant changes in the SMI and dentin thickness after canal instrumentation. TN files demonstrated less straightening of the canal curvature compared to VB files with no statistically significant difference. Furthermore, TN files showed less cervical dentin removal when compared to VB files with no significant difference. A significant difference was found in TN group regarding dentin removal between coronal and apical thirds. Conclusion: Vortex Blue and TruNatomy files produced comparable root canal preparation with no considerable shaping mishaps or errors. Both files induced minimal canal straightening after preparation. TN files resulted in less removal of cervical dentin compared to apical dentin.

“…The study compared a modified form of the ProTaper Next shaping technique (PTNm) with the TruNatomy (TN) regarding lower molar mesial curved canals. They found that these techniques were equally helpful in shaping the canals [26]. The use of micro-CT in comparing the intervention or diagnosis techniques is also reported by Alshehri et al [27] and Saberi et al [28].…”

Introduction: The root canal system (RCS) is among the complex parts of the body that consists of several anatomical variations. The RCS has also been classified according to different classifications. In one of the classification systems, the RCS consists of the main canal, lateral canal, collateral canal, secondary canal, intercanal, accessory canal (AC), and recurrent canal, whereas in the other classification system, which was presented by the American Association of Endodontists (AAE) in 2020, the RCS consists of the C-shaped canal, lateral canal, furcation canal, and AC. Many researches have already been conducted on using micro-CT in describing the RCS classification in various teeth groups in the jaws. The micro-CT is a method used for the endodontic study, including the morphological study of the RCS. It is one of the non-destructive and high-resolution techniques that is beneficial in obtaining three-dimensional (3D) teeth structures. The method is similar to computed tomography and allows obtaining sections as well as 3D reconstruction of the studied object. Based on the above-mentioned findings, the authors discussed that canals are usually more long oval or ribbon-shaped at the coronal levels, then become oval or round shaped about 1 mm from the apical foramen, indicating that canal shape and number change in the apical third. Conclusion and future perspectives: The micro-CT could be a useful technology in the clinical study of canals, developmental grooves, and comparison of treatment and diagnostic strategies.

“…Measurements of canal transportation made using micro-CT imaging have been increasingly used in endodontic research. This is a nondestructive, reproducible, and well-established method to assess the quality of the biomechanical shaping of new instruments and techniques engineered to facilitate the reduction of procedural errors (Hwang et al, 2014;Zhao et al, 2014;Pedullà et al, 2016;Yang et al, 2016;Brasil et al, 2017;Shah et al, 2017;Berutti et al, 2022). Freire et al (2012) compared two methods of assessing apical transportation in curved canals after rotary instrumentation, namely, cross sections and micro-CT.…”

Aim: The study aimed to evaluate the shaping characteristics of ProTaper Ultimate (Dentsply Sirona) and BlueShaper (Zarc4Endo) using microcomputed tomographic imaging technology (micro-CT).Methods: Thirty mesial and distal canals of extracted second mandibular molars with similar anatomy were selected and scanned pre- and postoperatively by micro-CT scanning (SkyScan 1172, Bruker micro-CT) with a voxel size of 11 μm and shaped with two different procedures: ProTaper Ultimate (Group 1: n = 15) and BlueShaper (Group 2: n = 15) were used following the manufacturer’s recommendations up to final 30 apical size. Irrigation was ensured in all groups with 5.25% NaOCl and 10% EDTA during instrumentation. Canal transportation, the volume of removed dentin, and area of untreated surface were matched with preoperative values with Bruker CT Analyser (Bruker micro-CT). Data were statistically analyzed using Student’s t-test.Results: No significant differences were observed between Group 1 and Group 2 in terms of canal transportation, volume of removed dentin, and untreated surfaces. A significant difference (p < 0.05) in the amount of untreated surfaces was found between the mesial and distal canals in both groups.Conclusion: Shaping procedures with both ProTaper Ultimate and BlueShaper demonstrated similar canal enlargement volumes and similar canal transportation without evidence of significant preparation errors. Nevertheless, a high amount of untreated surface was reported for both systems, particularly in distal canals.
