三种根管治疗器械对根管内充填物清除效果对比
Effects Comparison of Three Different Root Canal Instruments in Removing Filling Materials within Root Canal
摘要
Abstract
Objective To compare efficiency among Mtwo nickel titanium file, ProTaper Universal retreatment system and stainless steel H file by hand use in removing filling materials during root canal retreatment. Methods A total of 60 maxillary incisors extracted by advanced periodontitis from January to July 2017 were treated with conventional root canal preparation and cold lateral condensation technique, and the samples were divided into group A, B and C according to therapeutic methods ( n=20 in each group) . Group A was treated with stainless steel H file, and group B was treated with Mtwo nickel titanium file, and group C was treated with ProTaper Universal retreatment system. Operative time was also recorded, and debris weigh in apical foramen and cleaning degree of root canal were compared. Results Filling ma-terials were all found in the three groups, In group B and C, values of weight of debris extrusion, clearing degree of tubal wall and operative time were better than those in group A (P<0. 05). Conclusion The three instruments can not com-pletely remove filling materials within root canal, but nickel titanium instruments can significantly improve clinical effi-ciency.关键词
