本研究探讨含氟漱口水对一步法自酸蚀黏结剂与牛牙根本质黏结的影响。将NaF溶液（0、450、900或9，000 ppm）施加到牛牙根牙本质表面持续30秒（立即）或在粘合一体式粘合剂之前进行。进行了微拉伸粘结强度（mu TBS）测试和耐酸碱区（ABRZ）扫描电镜（SEM）观察。使用双因素方差分析和Bonferroni校正的t检验分析μ TBS值和计算的ABRZ面积。显著性水平设定为P = 0.05（n = 30）。采用Bonferroni校正的Mann-Whitney U检验分析断裂模式。显著性水平设定为P = 0.00178（n = 30）。μ TBS在对照、450 ppm F和900 ppm F样本之间没有显著差异（P> 0.05），但在9，000 ppm F样本中显著较低（P < 0.05）。扫描电镜显示，氟应用后，在粘接剂-牙本质界面，包括ABRZ的抗酸性显着增加。
This study investigated the effect of fluoride mouthrinses on bonding of a one-step self-etch adhesive to bovine root dentin. Application of a NaF solution (0, 450, 900, or 9,000 ppm) to bovine root dentin surfaces was performed for 30 s (immediate) or before bonding of an all-in-one adhesive. Micro-tensile bond strength (mu TBS) testing and scanning electron microscopic (SEM) observation of the acidbase resistance zone (ABRZ) were performed. mu TBS values and calculated ABRZ areas were analyzed by using two-way ANOVA and the t-test with Bonferroni correction. The significance level was set at P = 0.05 (n = 30). Fracture mode was analyzed with the Mann-Whitney U test with Bonferroni correction. The significance level set at P = 0.00178 (n = 30). mu TBS did not significantly differ between the control, 450 ppm F, and 900 ppm F specimens (P> 0.05) but was significantly lower in 9,000 ppm F specimens (P < 0.05). SEM showed a significant increase in acid resistance at the adhesive-dentin interface, including the ABRZ, after fluoride application.
