| 摘 要： | 目的 观察脉冲CO2激光和38%氟化氨银联合处理对人牙本质超微结构的影响.方法 将人离体前磨牙预备成相同的4块牙本质标本,分为对照组(不处理)、激光照射组、氟化氨银组和联合处理组,采用扫描电镜观察牙本质的超微结构.结果 扫描电镜下可见,对照组的牙本质小管结构明显,切面不整齐呈杂乱锐利的断茬样结构;激光照射组牙本质表面熔融平坦,牙本质小管完全封闭;氟化氨银组牙本质表面有泡状结构隆起,覆盖牙本质表面,牙本质小管完全封闭;联合处理组与氟化氨银组表现相似,但泡状结构萎陷平坦,牙本质小管完全封闭.结论 应用脉冲CO2激光或38%氟化氨银处理均可封闭牙本质小管开口,两者联合使用可形成协同作用.

| Abstract: | Objective To explore the effect of combination of pulsed CO2 laser irradiation and diammine silver fluoride treatment on the ultrastructure of dentine.Methods Each extracted molars was made into four identical dentinal specimens,which were randomly divided into 4 groups according to the treatment methods: A,control group;B,pulsed CO2 laser irradiation;C,coated with 38%Ag(NH3)2F;and D,laser irradiation plus fluoride.Scanning electron microscope(SEM) analysis was performed.Results As shown by SEM,group A show... |
