摘要： 目的:评价臭氧水溶液对根管内壁牙本质微硬度的影响。方法:选取40颗因正畸拔牙的离体前磨牙随机分为5组,A组:2.15 mg/L臭氧水溶液组;B组:1%次氯酸钠组;C组:3%过氧化氢组;D组:15%EDTA组;E组:蒸馏水组(阴性对照组)。将牙冠于牙颈部截断后将牙冠沿牙体长轴纵向劈开暴露牙本质,以5组不同根管冲洗液分别处理5 min、15 min后用微硬度测试仪测定牙本质的微硬度。结果:1%次氯酸钠,3%过氧化氢,15%EDTA均降低了牙本质的微硬度,尤以15%EDTA为甚,而2.15 mg/L臭氧水溶液对牙本质微硬度无明显影响。结论:2.15 mg/L臭氧水溶液作为根管冲洗液对牙本质微硬度没有影响。

Abstract: Objective: To study the effect of ozonized water as endodontic irrigation solvents on dentin micro-hardness of human teeth. Methods: Extracted human premolar crowns were cut along long axis and treated with 2.15mg/L ozonized water, 1%NaOCL, 3%H2O2, 15%EDTA and distilled water respectively for 5min and 15min. The micro hardness of dentin was measured. Results: 1%NaOCL, 3%H2O2 and 15%EDTA decreased the micro hardness of dentin, especially 15%EDTA, while ozonized water was harmless to dentin micro hardness. Conclusion: It is recommended to apply 2.15mg/L ozonized water as endodontic irrigation.
