| Summary: | Shaping Ability of Three Different Rotary Nickel Titanium Systems An In Vitro StudyAim: The aim of the study was to compare the changes in transportation and changes in curvature after instrumentation in WaveOne Gold (WOG) system and One Curve (OC) system. Protaper Next (PTN) system was used as reference for comparison.Material and Methods: A Sixty-five human mandibular first molars were selected. Teeth were randomly allocated into three groups (n=15): Group 1: PTN; Group 2: WOG; Group 3: OC. Cone beam computed tomography (CBCT) were taken for all specimens before instrumentation. Pre instrumentation evaluation for angle of curvature was done using Schneider method. Also, transportation was evaluated using Gambill’s method. After instrumentation, radiographs (CBCT) were taken and changes in transportation and curvature were measured using Planmecca Romexis software. One-way ANOVA was used to compare between different groups, followed by Tukey’s Post Hoc test for multiple comparisons.Results: After root canal instrumentation, regarding transportation, Results showed significant difference between all groups at 6mm level as PTN group showed highest transportation (P=0.09). While there’s insignificance between 3mm and 9 mm level. As for changes in curvature, there was insignificant difference between groups (P=0.46).Conclusion: Single file system respected the original canal anatomy compared with multi-sequence file system. |
