The ongoing advancement of materials and methods for root canal instrumentation is resulting in improved techniques with minimal variations to the canal morphology. One standard for assessment of the shaping quality of curved root canals is preparation-induced straightening of the canal. The aim of the study: To compare the effects of 2 Nickel-Titanium rotary systems, 2Shape (Micro-Mega, Besançon, France) and ProTaper Next (Dentsply,Sirona, Ballaigues, Switzerland), on maintaining the distobuccal canals curvature of extracted human maxillary molar teeth using periapical radiographs. Materials and methods: In this study a total of 26 distobuccal roots of upper maxillary molars were used and divided into 2 groups: Group 1 (n=13) root canals prepared with 2Shape system (TS1, TS2) (Micro-Mega, Besançon, France) and Group 2 (n=13) root canals prepared with ProTaper Next (X1, X2) (Dentsply,Sirona, Ballaigues, Switzerland). A buccolingual radiograph was taken for every sample before and after instrumentation in the same position, and the postoperative angle of curvature was measured with the Image J Software and the same principle of the method of Schneider. The post instrumentation curvature degree was subtracted from the pre instrumentation curvature degree and these results represented the degree of straightening. Result: P< 0.05 was significant for ProTaper Next and 2Shape. 2Shape respected better the curvature angulations than ProTaper Next. Conclusion: Selection of the instruments has an important influence on the respect of the root canal curvature angulations.
