Abstract
Background Complete removal of debris during the process of root canal therapy is of paramount importance in order to achieve the objectives of endodontic treatment. Objectives This in vitro study was conducted to compare the effciency of four different rotary instrumentation systems in removing dentin debris at three levels of root canals. Materials and methods Sixty freshly extracted human mandibular premolar with single straight root canals were selected and randomly divided into four groups of fهfteen teeth each; Group I: prepared by rotary ProTaper system (Full rotary technique), Group II: prepared by single fle Reciproc system (Reciprocating technique), Group III: was prepared by single fle WaveOne system (Reciprocating technique), and Group IV: was prepared by single fle OneShape system (Full rotary technique). These groups were prepared to an apical preparation corresponding to size 25 K-fle. Sodium hypochlorite (3%) was used as an irrigant in all cases. After canals preparation, the roots were split longitudinally and photographed with a professional digital camera. The images of root sections were then magnifed to 100x and the percentage of remaining dentin debris was calculated for the apical (0-3 mm), middle (3-6 mm) and coronal (6-9 mm) levels through dividing the pixels occupied by debris at each level by the total pixels representing the entire area of the canal using Adobe Photoshop CS6. Data were analyzed statistically using ANOVA and LSD tests. Results Reciproc, WaveOne and OneShape systems showed signifcantly better cleaning effciency than Protaper system in the apical and coronal levels (p < 0.05). While in the middle level, no signifcant differences were obtained among all systems (p ≤ 0.05). Conclusion Under the conditions of this study, the use of OneShape, WaveOne and Reciproc systems was signifcantly more effective than ProTaper system in eliminating debris from root canals at all levels.
