Étude comparative de la préparation des canaux courbes sur dents extraites à l'aide de 3 systèmes : protaper universal, oneshape et waveone

Abstract : Objectives: Shaping is an essential step of successful endodontic treatment. Maintaining the original canal shape is one of the mechanical requirements of root canal shaping according to Schilder. New single-files systems that have been commercialized outiline the importance of the technological advances that have been made. We chose to compare the capacity of different single-file systems, WaveOne™ and OneShape®, at centering the root canal preparation, with a multi-file system, Protaper® Universal. Materials and Methods: The same operator shaped natural root canals (n=45) with the three different systems. we measured at three different levels ; the centering ability, the centering ratio, the amount of dentine removed, the percentage of non-prepared surfaces, the apical transportation of debris and the time required. Results: All groups showed satisfactory shaping ability and respect of the canal curvature proven by a miner deplacement of the root canal center. Our results also show that there is no significant difference in the centering ability of the three systems. Conclusions: There is no significant difference in the centering capacity of the different systems that were studied. Single-file systems allow a slight gain of time that should be put to profit on an abundant and repeated irrigation.
