Comparative evaluation of canal transportation, centering ability, and dentin removal between ProTaper Gold, One Curve, and Profit S3: An in vitro study

Abstract

Aim: The aim of the study was to compare the canal transportation, centering ability, and dentin removal of Profit S3 (PS3), One Curve (OC), and ProTaper Gold (PTG) systems using cone-beam computed tomography (CBCT). Materials and Methods: Thirty extracted human single-rooted premolars were used in the present study. Preinstrumentation scanning of all the teeth in arch form was taken using CBCT. To increase standardization, crowns were removed and only teeth measuring 16 mm were included in the study. The samples were randomly divided into three groups, with ten samples in each group; Group I was instrumented with PS3, Group II was instrumented with OC, and Group III – PTG. Postinstrumentation scans were performed, and the two scans were compared to determine canal transportation, centering ability, and dentin removal at 3, 6, and 9 mm, from the apex. Statistical Analysis: One-way-ANOVA and the independent t -test were done for the pairwise comparison. The significance level was set at P = 0.05; statistical analysis was performed with SPSS statistics version 20.0 (SPSS Inc., Chicago, IL, USA). Results: The mean canal centering ratio and canal apical transportation for PS3, OC and PTG show no statistical difference ( P > 0.05). The mean value of dentin removal showed a statistically significant difference between the three groups ( P < 0.05). PS3 and OC rotary file showed less removal of dentin compared to PTG ( P < 0.00). Conclusion: It was evident that PS3, OC, and PTG had no statistically significant difference when analyzed based on canal transportation and canal centering ratio. However, there was a significant difference among the three groups comparing the removal of dentin. PS3 and OC rotary file showed less removal of dentin compared to PTG.

Centering ability and root canal transportation of protaper gold and v taper gold using cone-beam computed tomography: An in vitro study

“…In an evaluation of centering ability and root canal transportation by Antony SDP et al [15] , no difference was observed between Profit S3 (PS3), One Curve (OC), and PTG. Also, Elnaghy et al [24] reported no significant difference between PTG and Pro Taper Universal NiTi rotary systems in root canal shaping abilities of mesial canals of mandibular first molars at three levels of 3-, 5-, and 7 mm.…”

“…The results indicated that the two instruments were well centered in the root canal at various levels from the root apex. Manufacture processing with heat-treated file systems can explain this because of its influence on making them more flexible and less straightening during instrumentation [15] . In our study, canal transportation among the two groups showed a significant difference in MD direction with more transportation of PTG at 3-and 6-mm levels.…”

“…Many techniques are used to compare pre-and postinstrumentation canal shape in order to assess shaping ability and canal transportation involving radiography, serial sectioning technique, photographic assessment, scanning electron microscope, computer manipulation technique, and micro-computed tomography [18,19] but CBCT as the latest one has some advantages such as; being noninvasive, low-dose radiation compact instrumentality, the possibility of detailed images analysis with different settings [20] . Several studies compared the centering ability and canal transportation of PTG with other instruments [8,15,[21][22][23][24][25][26] , while there has been no assessment on VTB instruments up to now. Less canal transportation of PTG instruments is due to proprietary heat treatment technology in comparison with other ProTaper files such as ProTaper Universal and ProTaper Next [27] .…”

Cone-beam computed tomography evaluation of shaping ability of kedo-S square and fanta AF™ baby rotary files compared to manual K-files in root canal preparation of primary anterior teeth

“…Concerning centering ability in the current study, the highest ratio of teeth specimens with perfect root canal centralization was found in the Kedo-S Square group with non-significant statistical differences among the three groups at different root canal levels ( P > 0.05). This may be explained by the heat treatment of Ni-Ti rotary files which leads to an increase in the file’s flexibility, renders higher torsional resistance, adapts the file to the contour of the primary root canal, and aids less straightening during instrumentation [ 37 , 38 ]. Moreover, the high centering ability of the Fanta AF™ Baby file group could be related to working in a crown-down technique with rotation motion [ 39 ].…”

Comparative evaluation of remaining dentin thickness, canal centering ability and apical deformity between ProFit S3 and Protaper gold – A nano CT study

“…The PS3 has exceptional flexibility, fracture resistance, and form memory. The taper can be ranging between 4 % and 8 % ( Antony et al, 2020 ).…”
