To evaluate the influence of different air-blowing durations on the micro-tensile bond strength (μTBS) of five current one-step adhesive systems to dentin.
One hundred and five caries-free human molars and five current one-step adhesive systems were used: ABU (All Bond Universal, Bisco, Inc.), CUB (CLEARFIL™ Universal Bond, Kuraray), GPB (G-Premio BOND, GC), OBA (OptiBond All-in-one, Kerr) and SBU (Scotchbond Universal, 3M ESPE). The adhesives were applied to 600 SiC paper-flat dentin surfaces according to each manufacturer's instructions and were air-dried with standard, oil-free air pressure of 0.25MPa for either 0s, 5s, 15s or 30s before light-curing. Bond strength to dentin was determined by using μTBS test after 24h of water storage. The fracture pattern on the dentin surface was analyzed by SEM. The resin-dentin interface of untested specimens was visualized by panoramic SEM image. Data from μTBS were analyzed using two-way ANOVA (adhesive vs. air-blowing time), and Games-Howell (a=0.05).
Two-way ANOVA revealed a significant effect of materials (p=0.000) and air-blowing time (p=0.000) on bond strength to dentin. The interaction between factors was also significantly different (p=0.000). Maximum bond strength for each system were recorded, OBA/15s (76.34±19.15MPa), SBU/15s (75.18±12.83MPa), CUB/15s (68.23±16.36MPa), GPB/30s (55.82±12.99MPa) and ABU/15s (44.75±8.95MPa). The maximum bond strength of OBA and SUB were significantly higher than that of GPB and ABU (p<0.05).
The bond strength of the current one-step adhesive systems is material-dependent (p=0.000), and was influenced by air-blowing duration (p=0.000). For the current one-step adhesive systems, higher bond strengths could be achieved with prolonged air-blowing duration between 15-30s.
评估不同吹干时间对五种市售单步粘结系统与牙本质的微拉伸粘结强度（μTBS）的影响。
使用105颗无龋的人磨牙和五种市售单步粘结系统：ABU（全粘结通用型，Bisco公司）、CUB（可乐丽菲露通用粘结剂，可乐丽公司）、GPB（G-优备粘结剂，GC公司）、OBA（全效粘结剂，登士柏公司）和SBU（3M通用粘结剂，3M ESPE公司）。根据各制造商的说明，将粘结剂应用于600个碳化硅砂纸打磨的牙本质表面，并在光固化前用0.25MPa的标准无油气压吹干0秒、5秒、15秒或30秒。在储存24小时后，通过微拉伸粘结强度测试确定与牙本质的粘结强度。通过扫描电子显微镜（SEM）分析牙本质表面的断裂模式。通过全景扫描电子显微镜图像观察未测试样本的树脂-牙本质界面。使用双向方差分析（粘结剂与吹干时间）和Games-Howell检验（α=0.05）分析微拉伸粘结强度的数据。
双向方差分析显示，材料（p=0.000）和吹干时间（p=0.000）对与牙本质的粘结强度有显著影响。因素之间的相互作用也有显著差异（p=0.000）。记录了每个系统的最大粘结强度，OBA/15秒（76.34±19.15MPa）、SBU/15秒（75.18±12.83MPa）、CUB/15秒（68.23±16.36MPa）、GPB/30秒（55.82±12.99MPa）和ABU/15秒（44.75±8.95MPa）。OBA和SBU的最大粘结强度显著高于GPB和ABU（p<0.05）。
当前单步粘结系统的粘结强度取决于材料（p=0.000），并受吹干时间的影响（p=0.000）。对于当前的单步粘结系统，在15 - 30秒之间延长吹干时间可获得更高的粘结强度。
