本研究的目的是评估使用相同压力(0.25 MPa)的空气吹扫持续时间对一体化系统的粘结性能的影响。三种一体化系统是:EB(Easy Bond,3 M ESPE,USA)、BB(BeautiBond,Shofu Inc.,日本)和GBp(G-Bond plus,GC Corporation,日本)。在施加粘合剂之后,随后使用7个不同的持续时间(5 s、10 s、15 s、20 s、25 s、30 s和35 s)对3个系统进行空气吹扫。在24 h水储存后,使用µTBS测试确定与牙本质的粘结强度。此外,通过扫描电镜对树脂-牙本质界面和牙本质侧的断裂面进行了评价。每个系统的最大µTBS,BB(40.4±14.8 MPa)、EB(79.8±16.5 MPa)和GBp(47.3±17.6 MPa)分别记录为15 s、15 s和25 s吹气持续时间。在相同的气压下,吹气时间的长短会影响胶层的蒸发量和厚度,从而导致不同的粘接强度。
The purpose of this study was to evaluate the effect of air-blowing duration on the bonding performance of all-in-one systems using the same pressure (0.25 MPa). Three all-in-one systems were: EB (Easy Bond, 3M ESPE, USA), BB (BeautiBond, Shofu Inc., Japan) and GBp (G-Bond plus, GC Corporation, Japan). After adhesive application, the 3 systems were air-blown thereafter using 7 different durations (5 s, 10 s, 15 s, 20 s, 25 s, 30 s and 35 s). Bond strengths to dentin were determined using µTBS test after 24 h water storage. In addition, evaluation of both the resin-dentin interface and the fractured surface on the dentin side were performed by SEM. The maximum µTBS for each system, BB (40.4±14.8 MPa), EB (79.8±16.5 MPa), and GBp (47.3±17.6 MPa), were recorded with 15 s, 15 s and 25 s air-blowing duration respectively. Under the same air-pressure, the air-blowing duration could affect evaporation and the thickness of the adhesive layer, which contributed to the different bond strengths.
