摘要
目的评价使用机用镍钛器械Protaper改良法预备根管的临床效果。方法选择临床上患有牙髓炎、根尖周炎的需要进行根管治疗的患者200例,按前牙、双尖牙、磨牙随机分成两组,每组100例,实验组采取Protaper根管机动预备改良法,热牙胶垂直加压充填,对照组采取Protaper根管机动预备标准法,热牙胶垂直加压充填。记录两组根管预备所需时间、器械折断数量、术前、术中、术后X线片评价预备和根充效果。结果实验组与对照组预备根管,根管锥度、流畅性、根管形态及工作长度改变,两组间无显著差异,但根管预备时间实验组与对照组相比明显缩短,有显著差异。结论使用机用镍钛器械Protaper改良法预备根管是可行的,提高了根管预备的效率,但要事先做好疏通,防止器械的折断。
Objective To evaluate the clinical effect of the improved method of root canal preparatibn using Protaper nickel-titanium instruments for machine. Methods 200 patients suffering from pulpitis, periapical that need root canal treatment,were divided into two groups according to anterior teeth,premolars,molars randomly, each 100 patients,the experimental group used the improved method of root canal preparation,filled with warm gutta vertical condensation.Control group used the standard method of root canal motor preparation. Filled with warm gutta vertical condensation.Record the time that two sets of root canal preparation requi^ed, ,lhe~ number of equipment broken, X-ray film preoperative,intraoPerative,and postoperative to evaluate effect n~ preparation and root filling. Results Experimental group and control group,root canal taper,fluency,root canal morphology and working length changes,no significant differences,but the root canal preparation time of experimental group.was significantly shortened compared to control group,there was significant differences. Conclusion The improved method of root canal preparation using protaper nickel-titanium instruments for machine is feasible,it improved the efficiency of root canal preparation,but needed well dredge in advance to prevent the breakage of equipment.
