摘要
Abstract
Objective:To evaluate the effect of severely curved root canal preparation using PathFile and ProTaper rotary instruments. Methods:One hundred and twelve molars with 331 root canals including 134 severely curved root canals with 25 or higher degrees of root canal curvature were randomly divided into two groups. Root canals were prepared with Path-File and ProTaper in group A,and were prepared with ProTaper in group B. All root canals were filled with continuous wave condensation. The operating time for each root canal,the apical transportation and the incidence of instrument separation of both this two groups were recorded. Results:The mean operation time in group B was significantly shorter than that in group A,there was statistically significant difference between this two groups ( P<0. 05 ) . The incidence of instrument separation and the apical transportation in group A were significantly less than that group B,and there was better filling effect in group A. There were statistically significant difference between this two groups ( P<0. 05 ) . Conclusion:Combined application of PathFile and ProTaper rotary instruments for preparation of severely curved root canal of molars is safe,and has lower apical transportation with better filling effect.关键词
