Abstract
Objective:To evaluate the curved root canals preparation ability of K3 combined with TF Ni-Ti rotary instruments.Methods:Eighty human mandibular premolars and molars were divided into two groups in-cluding mild curve and moderate-severe curve group according to the angles of canal curvature,each group in-cluded 40 teeth.Each group were randomly divided into K3 +TF and K3 group respectively according to the preparation method group.The operating time,occurrence of complications,degree of straightening of root canal and centering ability of the instruments for each root canal were recorded and analyzed.Results:In the mild curve group,the operating time with K3 +TF was significantly shorter than that with K3;In moderate-severe curve group,statistically significant difference was found in operating time, occurrence of complications, degree of straightening of root canal and centering ability at measuring points 1~4 mm between group K3+TF and group K3.Conclusion:Curved root canal prepared by K3 files combined with TF files using less time and occurring fe-wer complications than using K3 files alone.Also the combination group can maintain the original canal curvature better,especially for the moderate-severe curved root canal.关键词
