Abstract

Aims. The purpose of this study was to compare the effects of 3 different rotary Ni-Ti instruments used to prepare curved root canals on the root canal curvature by using Digora system. Methods. Mesiobuccal canals of 30 mandibular first molars with curvature between 20-40 degrees were divided into 3 equal groups according to Ni-Ti rotary system need for root canal preparation: Alpha, RaCe and ProTaper system. Root canal curvatures from both buccal and proximal view were measured before and after instrumentation by using Digora system and image analysis software according Schneider's technique. Results. The result indicated that ProTaper system showed significantly greater decrease in curvature in the mesio-distal view and in the bucco-lingual view (p<.05). Conclusion. The current study concluded that the rotary Ni-Ti RaCe system better maintained the original root canal curvature than the rotary Ni-Ti Alpha System and ProTaper Universal Systems. It may be better to use the rotary Ni-Ti RaCe system to prepared curved canal in order to maintained the original root canal curvature.
