硬化牙本质
    Ultrastructural study of sclerotic dentin in non-carious cervical lesions disposed by a total-etching dentin adhesive
    牙颈部非龋性硬化牙本质经全酸蚀牙本质粘接剂处理后的超微形态
    Ultrastructural study of non-carious cervical sclerotic dentin bonded by a all-in-one self-etch adhesive
    牙颈部非龋性硬化牙本质经自酸蚀粘结剂处理后的超微形态
    Ultrastructural study of a self-etching adhesive to sclerotic dentin in non-carious cervical lesions
    牙颈部非龋性硬化牙本质粘接的超微形态研究
    Ultrastructural study of sclerotic dentin in non-carious cervical lesion treated by three different etching modes
    3种酸蚀方法处理硬化牙本质表面的超微形态研究
    Effect of acid etching time on bonding interface of non-carious cervical sclerotic dentin
    酸蚀时间对牙颈部非龋性硬化牙本质粘接界面形态的影响
    Both the hybrid zone and resin tags were observed in sclerotic dentin after restoration, although the resin tags were fewer and in lack of communications, the length of resin tags and the thickness of the hybrid zone were almost similar to those of the sound dentin.
    全酸蚀粘接剂ScotchbondMulti purpose不能酸蚀掉小管内的矿化结晶 ,粘接修复后 ,硬化牙本质与树脂的界面可见到清晰的混合层和树脂突 ,混合层的厚度和树脂突的长度与正常牙本质相似 ,但树脂突的数量较正常牙本质少 ,树脂突之间交通枝少见。
    Conclusion: Bonding to sclerotic dentin is different from sound dentin, and may be compromised by the fewer resin tags and communications.
    结论 :硬化牙本质的粘接特性与正常牙本质存在差异。 树脂突的数量及交通枝不足是硬化牙本质粘接强度受限的可能因素。
    Results Most dentinal tubules were occluded by rod-like sclerotic casts in the sclerotic dentin surface.
    结果硬化牙本质的牙本质小管大部分被柱状的矿化结晶体堵塞。
    Conclusions Bonding to sclerotic dentin is different from sound dentin and may be compromised by occluded dentin tubules.
    结论硬化牙本质的粘接与正常牙本质存在差异,牙本质小管内的矿化结晶可能影响粘接效果。
    After restoration the resin tags were fewer and shorter in sclerotic dentin than those in sound dentin.
    硬化牙本质与树脂的粘结界面可见到树脂突,但与正常牙本质比较,树脂突的数量较少、长度较短。
    Conclusions:Bonding to sclerotic dentin is different from that to sound dentin, and may be compromised by the fewer resin tags.
    结论:硬化牙本质的粘结特性与正常牙本质存在差异。 树脂突的数量及长度不足可能影响硬化牙本质的粘结。
    Objective:To examine the effect of acid etching time on the bonding interface of non-carious cervical sclerotic dentin.
    目的:观察酸蚀时间对牙颈部非龋性硬化牙本质-树脂粘接界面超微结构的影响。
    Objective This in vitro study was to evaluate the micro-tensile bond strength(μTBS) of three adhesives to sclerotic dentin in non-carious cervical lesions.
    目的采用微拉伸粘接强度实验测定3种牙本质粘接剂粘接楔状缺损处硬化牙本质的粘接强度。
    Results μTBS of Seotchbond and Contax to sclerotic dentin was significantly lower than to normal dentin. But μTBS of Adper Prompt L-Pop to normal dentin was significantly lower than to sclerotic dentin,μTBS to sclerotic dentin was Scotchbond 46.805 MPa,Adper Prompt L-Pop 39.045 MPa,and Contax 29.852 MPa.
    结果粘接剂 A、B、C 粘接硬化牙本质的微拉伸粘接强度分别为46.805 MPa、39.045 MPa、29.852 MPa。 粘接剂 A 和 C 与硬化牙本质的微拉伸粘接强度低于正常牙本质,而粘接剂 B 与之相反,差异有统计学意义(P<0.05)。
    Conclusion:The micro-tensil bond strengths of four dentin adhesives to sclerotic dentin is different, the bond strengths of Xeno Ⅲ group was lower than the other three adhesives(P<0.01=.
    结论:4种粘接剂对硬化牙本质粘接强度存在差异,XenoⅢ最低(p<0.01),其余3种粘接材料两两比较无显著差异(p>0.05)。
