“…ese results could be explained by the improved flexibility of WOG that would reduce canal transportation and maintain the canal geometry. e shaped canals demonstrated some degrees of canal transportation which is consistent with previous studies [11,[13][14][15]. e slight canal transportation in XPS and WOG toward the outer side at the canal exit level might be attributed to the tendency of the NiTi file to return to its original shape by the restraining forces of the file [3].…”

“…Literature showed that canal shaping is influenced by many factors such as file's alloy and geometry, thermomechanical manufacturing, and motion kinematics [9][10][11][12][13][14][15]. Contemporary advancements in NiTi file production contributed to the evolvement of single NiTi systems, in which the mechanical preparation of the root canal is completed using one file.…”

“…WOG file is made up of "gold wire" wherein the manufacturing process involves postmachining heat treatment of the files followed by a cooling cycle [12]. Moreover, the WOG file presents with a unique alternating off-centered parallelogram-shaped cross section, along with 2 cutting edges [12,13].…”

e aim of this study was to assess the shaping ability of the XP Shaper (XPS) file in severely curved canal models under simulated body temperature and compare it with that of the WaveOne Gold (WOG) file. Ninety-six simulated root canals were equally distributed into XPS and WOG systems to be shaped by eight files each. Files were assessed under a stereomicroscope prior to canal shaping to detect deformation if any. e canals were shaped at 35 ± 1°C using the X-Smart Plus motor. Images of the canals were obtained before and after instrumentation using a stereomicroscope to measure the amount of removed resin from both the inner and outer curvature sides at apex (0 mm) and 3 mm and 6 mm from the apex. e shaping time was calculated. e data were statistically analyzed by the independent t-test at 5% significance level. e XPS and WOG systems shaped the canals in 37.0 ± 9.5 and 62.6 ± 11.3 seconds (P < 0.05), respectively. At the apex level, the amount of resin removal in both sides did not show a significant difference between the tested groups (P > 0.05). At 3 mm and 6 mm levels, the WOG removed more resin than XPS at both sides (P < 0.05). In XPS, deformation was observed in four files: one file after the first use, one file after the fourth use, and two files after the sixth use. In WOG, two files were deformed: one file after the fifth use and one file after the sixth use. One XPS file was fractured after the sixth use. In short, XPS and WOG files can be used in shaping severely curved canals as they showed the ability to maintain the original shape with minimal transportation. Both file systems showed signs of deformation after use with a lower number of deformed files observed in WOG throughout the experiment.

“…Pre-enlargement provided by the glide path allows the root canal preparation instruments to work with less torsional stress, reducing the risk of instrument fracture. 1,[3][4][5][6][7][8][9] Although not statistically significant, the highest mean transportation values have been observed when the glide path is not prepared before the final canal instrumentation. 1 Therefore, the performance of the file system might be enhanced by preparation of a glide path before the final shaping.…”

“…The WOGG is manufactured using NiTi Gold alloy, has a parallelogram cross-section, along with a semi-active guiding tip 0.15 mm in diameter, and variable conicity ranging from 2 to 6%. 9 The progressive tapered design of these file systems provides a glide path and preliminary enlargement of the root canal in the middle and coronal regions. This feature has been reported to reduce stress to the subsequent shaping NiTi rotary instruments.…”

Objectives The aim of this study was to compare the volume variation and maintenance of the root canal position when using the ProGlider 16.02 (PG) and the WaveOne Gold Glider 15.02 (WOGG) file systems for glide path preparation. Materials and Methods Twenty-four moderately curved mesiobuccal canals of maxil-lary first molars were selected and randomly divided into two groups: PG and WOGG. The selected teeth were scanned using microtomography before and after root canal preparation to assess centralization and linear transport at 1, 3, 5, and 7 mm from the apical foramen. Statistical Analysis The data were analyzed with the Mann–Whitney U test. The level of significance was 5%. Results There were no significant differences in volume variation or root canal transport (p > 0.05). There was a significant difference in the centralization of the root canal at 3 mm from the foramen (p < 0.05). Conclusions WOGG and PG instruments presented similar results regarding the root canal volume increase and transport. WOGG caused higher decentralization at 3 mm from the apical foramen.
