摘　　要：目的:探讨不同超声荡洗组合液对根管显微硬度的影响。方法:选取新鲜拔除的上颌单根管恒牙40颗。沿牙颈部将牙冠截除,Mtwo镍钛预备系统预备根管。随机分为四组,A组:3%NaClO和EDTA组合液,B组:3%NaClO和MTAD组合液,C组:CHX和H_2O_2组合液,D组:蒸馏水进行超声荡洗。对每组样本的根管的显微硬度进行测量并比较。SPSS 19. 0对数据进行统计学分析。结果:A组显微硬度明显低于其他各组,差异显著(P <0. 05)。B组显微硬度低于C,D两组,差异显著(P <0. 05)。C,D两组显微硬度比较无显著差异(P> 0. 05)。结论:3%NaClO和EDTA组合荡洗液,3%NaClO和MTAD组合荡洗液对根管硬度均产生不同程度的影响,其中3%NaClO溶液和EDTA组合荡洗液对根管的硬度的影响较大,H_2O_2和CHX混合液对根管硬度影响较小为较好的根管荡洗液。Objective： To investigate the effect of different ultrasonic wash combination on root canal microhardneas. Methods： 40 fresh maxillary single - rooted permanent teeth were selected. The crown is truncated along the tooth neck and the Mtwo nickeltitanium preparation system prepares the root canal. Randomly divided into four groups, A group： 396 NaC10 and EDTA combination liquid, GroupB： 3% NaCIO and MTAD combination liquid, Group C： CHX and H202 combination liquid, Group D： distilled water and ultrasonic washing every group teeth. The microhardneas of the root canal of each group samples was measured and compared. SPSS 19. 0 for statistical analysis of the data, Results： The microhardness of group A was significant｜y lower than that of other groups （ P〈0. 05）. The microhardness of group B was significantly lower than that of group C and D （P 〈 0.05）. There was no significant difference in the microhardness between C and D （ P 〉0.05）. Conclusion： The combination of 3 % NaC10 and EDTA combination swinging lotion, 3 % NaC10 and MTAD combination swinging lotion have different effects on root canal hardness, The effect of 3 % NaC10 solution and EDTA cornbination winging lotion on the hardness of root canal was greater, and H202 and CHX mixed solution had less effect on root canal hardness, which was better root canal washing solution.
