چکیده
introduction: the purpose of this study was to evaluate and compare canal preparation pattern of k3 and protaper rotary files in curved resin blocks. materials and methods: twenty-four resin blocks were used in this experimental study and randomly divided into two groups. their initial images were scanned. after preparation, their images were scanned again in the same position. pre and post preparation images were superimposed by photoshop software and the removed resin was measured in 5 different points, and then analyzed statistically by anova and t-test. results: at o point (orifice), significantly (p<0.05) more outer canal wall was removed in the protaper group than in the k3 group. there was no significant difference at any other points of outer wall. removed material of inner canal wall was not significantly different between the two groups. conclusion: under the condition of this study, both systems performed acceptable preparation pattern except at the beginning of the curve.

AIMS This study aimed to compare the frequency of ProTaper rotary instrument fracture with rotary (conventional) and hybrid (rotary and hand files) canal preparation techniques. Secondary objectives were to determine whether there was an association of ProTaper file fracture with the canal curvature and to compare the mean time required for canal preparation in the two techniques. METHODS An ...

AIM To investigate physical parameters for ProTaper nickel-titanium (NiTi) rotary instruments whilst preparing curved canals in maxillary molars in vitro. METHODOLOGY A novel torque-testing platform was used to prepare root canals in 15 extracted human maxillary molars with ProTaper rotary instruments. Peak torque and force was registered along with numbers of rotations required to shape the ...
