| Abstract | ||||
| For endodontic therapy to be successful, the root canal space needs to be sufficiently biomechanically prepared. In this study, the three different rotary systems Fanta AF F One file, Neonitini rotary system, and 2Shape system had been employed to assess the cleanliness of root canals following root canal instrumentation using a stereomicroscope. Materials &Methods: In all, 45 recently extracted lower mandibular first molars had been chosen. In accordance with the NiTi rotary system used in canal instrumentation, root canals were divided randomly to three groups (15 teeth each), ensuring that each group had an equal representation of the curvature range of 25º to 40º using Schneider's method: Fanta AF F One file is Group 1. The Neonitini file rotary system is group 2. Group 3: Rotating 2-shape system. Using a stereomicroscope (Leica MZ12.5) with a 10X magnification, the effectiveness of cleaning had been assessed regarding the quantity of remaining dentinal debris in the inside of canal wall. Results: Fanta AF F One file system was significantly effective in eliminating debris in comparison to 2 shape and Neonitini file systems. The three file systems more easily cleaned the coronal and middle portions of the root canals but less easily cleaned apically. Conclusions: When compared to 2 shape and Neonitini rotary systems, the Fanta AF F One had superior cleaning capabilities at all root canal levels. | ||||
