“…XP-endo Shaper system was chosen for its better adaptation to the root canal anatomy as proposed by the manufacturer 7 , whereas the WaveOne Gold system was chosen because it is worldwide used and promotes a significant bacterial reduction within the root canal 1 . The preparations using both systems increased the root canal surface, which corroborates other studies assessing several automated systems 5 , 8 , 9 , 10 , 11 , 12 , 13 , 14 . Versiani et al 10 and Marques et al 14 found an increase of 10.8% and 11,3% respectively by using XP-endo Shaper files in long oval-shaped root canals, which are values close to ours, that is, 11.18%.…”

“…Different techniques and instruments have had difficulties in preparing root canals as untouched areas are always left after instrumentation 2 , 4 , 5 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 . The present study assessed XP-endo Shaper and WaveOne Gold systems before and after additional manual instrumentation in the preparation of long oval-shaped root canals.…”

“…Analysis of root canal preparation was carried out by using a micro-CT device, which is the most currently used method as it is non-destructive and allows three-dimensional analysis with accurate measurements, in addition to maintaining images for future studies 17 . Although long oval-shaped canal poses great difficulty in their preparation, the root canal of mandibular incisors and the distal root canal of mandibular molars have been mostly used in these studies 2 , 10 , 13 , 14 , 15 , 18 . Wu et al 19 found a higher incidence of long oval-shaped canals in mandibular incisors (56%) than in mandibular molars (30%) and for this reason, the mandibular incisor was the target of this study.…”

This study compared the preparation of long oval-shaped root canals using WaveOne Gold and XP-endo Shaper systems, both supplemented or not with manual instrumentation. Twenty-four long oval-shaped canals of mandibular incisors were distributed into two groups according to the instrumentation: WaveOne Gold Primary or XP-endo Shaper systems. All root canals were manually instrumented with a size 25 K-file after automated preparation. The specimens were scanned by using a micro-CT device (17.42 µm) before and after automated preparation and manual instrumentation. The increased surface of the root canal and the percentage of untouched areas were assessed. Both WaveOne Gold and XP-endo Shaper systems increased the root canal surface and had similar untouched areas (p>0.05). Supplementary instrumentation increased the surface of the root canal and decreased the untouched walls (p<0.05). WaveOne Gold and XP-endo Shaper systems provided a similar preparation of long oval-shaped canals and manual instrumentation improved their preparation.

Background: Single nickel-titanium (NiTi) files have been introduced in the endodontic market and used as only one instrument in various cases to prepare the entire root canal.Aim: changes in pulp volume in root canals of mandibular molar teeth were determined using cone-beam computed tomography (CBCT) after root canal preparation using three different single NiTi files (Reciproc Blue, XP-endo Shaper, and One-Shape). Materials & Methods:This trial included forty-five patients have first mandibular molars with a mesiobuccal canal curvature range of (25-35°), and distal oval canals. They were then allocated into three equal groups corresponding to the type of files used in the root canal instrumentation (Reciproc Blue, XP-endo Shaper, and One-Shape). Pre-and post-instrumentation scans were performed to match the pulp volumes from CBCT images. One-way ANOVA was used to identify possible differences in canals among groups corresponding to the instrumentation.Results: There was a significant difference in the volume change in the distal canals between the groups (D). There was no significant difference in the volume change between the mesiobuccal (MB) and mesiolingual (ML) canals. For the distal canal, there was a significant difference between XP-endo Shaper and Reciroc Blue (p=.008) and between XP-endo Shaper and One-Shape (p=.001). However, no significant difference in volume change was noted between the Reciroc Blue and One-Shape. Conclusion:The Reciproc Blue, XP-endo-Shaper and One-Shape files were equally effective in shaping the radicular part of mesial canals, XP-endo Shaper was more effective in shaping oval distal canals than Reciproc Blue, and One-Shape.

Polyester-short-fiber-reinforced rubber composites have been detected by an X-ray three-dimensional microscope, and then the three-dimensional reconstruction of the image has been carried out to characterize the orientation of polyester short fibers in the composites for the first time. Based on the summary of three traditional methods and mechanisms of characterizing the orientation of polyester short fibers by the numerical parameter method, the direct test method, and the indirect test method, the method and mechanism of the X-ray three-dimensional microscope applied to the orientation characterization of polyester short fibers have been studied. The combination of the center point and threshold segmentation methods has been used to distinguish which fiber section belongs to the same fiber, and the identification of the whole short fiber in different slice images has been realized for the first time. Moreover, Avizo software has been used to realize the three-dimensional reconstruction of a polyester short fiber scanning image. The obtained data have been integrated and the orientation angle and orientation degree have been quantitatively characterized for the first time. This has filled the key technical problem of quantitative characterization of the orientation angle and orientation degree of polyester fibers. The image has been verified by 3Dmed software, and furthermore, the accuracy of the three-dimensional reconstruction results has been verified.
