问题声明
当前牙科粘合剂在人工老化后的稳定性可能取决于粘合策略。
目的
评价热疲劳和水储存对4种粘附策略的牙本质微拉伸粘结强度（µTBS）的影响。
材料和方法
将48颗人磨牙分配到四种牙本质粘合剂：FL-OptiBond FL（Kerr Corporation，橙子，CA，USA）; SOLO-OptiBond SOLO Plus（Kerr Corporation）; XTR-OptiBond XTR（Kerr Corporation）;和AIO-OptiBond All-in-One（Kerr Corporation）。用混合复合材料修复牙齿，并将其切片以获得粘结梁。对于每种粘合剂，将三分之一的中心梁和外围梁分配到三种老化条件之一：（1）在蒸馏水中保持24小时（24 h）;（2）热循环（TC）20，000次循环;以及（3）在蒸馏水中储存6个月（6 M）。梁在拉伸模式下进行测试。使用方差分析和Fisher最小显著差异事后检验计算统计分析（p < 0.05）。
结果
使用XTR获得了24 h、TC和6 M的最高平均µTBS，但只有6 M的平均µTBS显著高于其他三种粘合剂。对于FL，平均µTBS从24 h至TC显著降低。对于SOLO，平均µTBS在三种老化条件下保持稳定。AIO的平均µTBS从24 h至6 M显著降低。
结论
对于所有三种测试条件，自蚀刻粘合剂XTR和AIO的表现类似于或优于蚀刻和冲洗粘合剂FL和SOLO。它们的老化稳定性似乎是材料依赖性的。
STATEMENT OF PROBLEM
The stability of current dental adhesives after artificial aging may depend on the adhesion strategy.
PURPOSE
To evaluate the effect of thermal fatigue and water storage on the dentin microtensile bond strengths (µTBS) of four adhesion strategies.
MATERIALS AND METHODS
Forty-eight human molars were assigned to four dentin adhesives: FL--OptiBond FL (Kerr Corporation, Orange, CA, USA); SOLO--OptiBond SOLO Plus (Kerr Corporation); XTR--OptiBond XTR (Kerr Corporation); and AIO--OptiBond All-in-One (Kerr Corporation). Teeth were restored with a hybrid composite, and sectioned to obtained bonded beams. For each adhesive, one-third of the central and peripheral beams were assigned to one of three aging conditions: (1) kept in distilled water for 24 hours (24 h); (2) thermocycled (TC) for 20,000 cycles; and (3) stored in distilled water for 6 months (6M). Beams were tested in tension mode. Statistical analysis (p < 0.05) was computed using Analysis of Variance and Fisher's Least Significant Difference post hoc test.
RESULTS
The highest mean µTBS for 24 h, TC, and 6M were obtained with XTR, but only the 6M mean µTBS were significantly higher than those of the other three adhesives. For FL, mean µTBS decreased significantly from 24 h to TC. For SOLO, mean µTBS remained stable over the three aging conditions. Mean µTBS for AIO decreased significantly from 24 h to 6M.
CONCLUSION
The self-etch adhesives XTR and AIO performed similarly or better than the etch-and-rinse adhesives FL and SOLO for all three testing conditions. Their aging stability seems to be material-dependent.
