摘要： 目的:比较几种不同自酸蚀粘接剂对流动树脂充填牙合面洞的边缘密封性的影响。方法:收集42颗拔除的完整第三磨牙,制备牙合面洞:2 mm×2 mm×2 mm,随机分为7组,分别使用不同粘接剂处理:A(SE Bond)、B(Liner Bond F)、C(SE Protect)、D(SE Bond 2)、E(SE One)、F(S3 Bond)、G(Universal Bond Kit)。流动树脂充填。使用声发射记录光固化开始前后2000 s的声发射事件,光学相干断层扫描检测树脂-牙体界面的密封性。结果:声发射信号在光固化开始后的150 s内声发射事件数迅速增长。E组的平均声发射事件数目最少且增长速率最慢,F组增长速率最快,B组的平均声发射事件数目最多。各组间声发射事件数无显著性差异。对于光学相干断层扫描,E组产生的界面间隙百分比最小,各组间无显著性差异。结论:声发射与光学相干断层扫描可以用来检测修复体与牙体间界面间隙的产生。一步法和两步法自酸蚀粘接剂的粘接效果没有显著性差异。

Abstract: Objective: To compare the influence of various self-etch adhesives on interfacial integrity restored with flowable resin composite. Methods: Forty-two extracted intact human third molars were selected and cavities of 2mm*2mm*2mm were prepared on the occlusal surface of the teeth. The prepared teeth were randomly divided into seven groups and treated with different self-etch adhesives: Group A (SE Bond), Group B (Liner Bond F), Group C (SE Protect), Group D (SE Bond 2), Group E (SE One), Group F (S3 Bond), and Group G (Universal Bond Kit). All of the teeth were restored with flowable resin composite and were light-cured for 20s. Acoustic emission (AE) events were recorded when the light-curing started, and last for totally 2000s during and after light-curing time. The interfacial integrity was detected by optical coherence tomography (OCT). Results: The cumulative AE number increased rapidly in the early time period until 150s. The AE number of Group E was the lowest, while the AE number of Group B was the highest. However, there were no significant differences among all groups. The percentage of interfacial debonding in Group E was the lowest. The percentages of interfacial debonding calculated by OCT were not significantly different in all groups. Conclusion: AE technology and OCT were effective methods to detect tooth-composite interfacial integrity. The interfacial integrity showed no significant difference between one-step and two-step self-etch adhesives.
