目的
评价一体化粘合剂作为窝沟封闭剂的临床效果。
方法
使用两种多合一粘合剂（One-Up Bond F和Xeno CF Bond）和两种树脂密封剂（Teethmate F-1和Helioseal F）在抛光和研磨的釉质表面之间制作树脂-釉质粘合样本。制备试样梁，并以1 mm/分钟的十字头速度进行微拉伸粘结试验。对所得粘结强度进行单因素方差分析和Scheffe’s F检验（P < 0.05：每组n=12）。为了评价磷酸和一体化粘合剂的蚀刻效果，通过FE-SEM检查处理的釉质表面（37%磷酸、40%磷酸或一体化粘合剂）。
结果
两种粘接剂对抛光牙釉质的粘接强度显著低于对磨面牙釉质的粘接强度（P < 0.05）。而磷酸树脂封闭剂在抛光和研磨牙釉质表面的修复效果无显著性差异（P > 0.05）。扫描电镜观察显示，37%和40%磷酸对牙釉质表面的腐蚀作用均大于多效粘结剂。
PURPOSE
To evaluate the clinical efficacy of all-in-one adhesives as fissure sealants.
METHODS
Resin-enamel bonded specimens were fabricated between polished and ground enamel surfaces using two all-in-one adhesives (One-Up Bond F and Xeno CF Bond) and two resin sealants (Teethmate F-1 and Helioseal F). Specimen beams were prepared and microtensile bond tests were performed at a crosshead speed of 1 mm/minute. The bond strengths obtained were subjected to one-way ANOVA and Scheffe's F test (P < 0.05: n=12 for each group). To evaluate the etching effect of phosphoric acid and the all-in-one adhesives, the treated enamel surfaces (37% phosphoric acid, 40% phosphoric acid, or all-in-one adhesives) were examined by FE-SEM.
RESULTS
The bond strengths of the two all-in-one adhesives tested to the polished enamel surface were significantly lower (P < 0.05) than to ground enamel. However, no significant differences (P > 0.05) were found between the polished and ground enamel surfaces for resin sealants using phosphoric acid. Under SEM examination, 37% or 40% phosphoric acid etched the enamel surface more than all-in-one adhesives.
