目的:本研究旨在评估一种通用型黏结系统在不同黏结策略下对深层牙本质的微拉伸黏结强度。材料和方法:将15颗人类第三磨牙的冠状部分去除,暴露深层牙本质,并根据粘合剂系统分为3组:G1(对照):2步全蚀刻(Adper Single Bond 2,3M ESPE); G2:1步自蚀刻通用粘合剂(Scotchbond Universal,3M ESPE); G3:2步全蚀刻通用粘合剂(Scotchbond Universal,3M ESPE)。在牙本质表面上进行复合材料构建,并在水储存24 h后,将牙齿切片,以获得每组40个粘结梁,其截面积为0.9 mm 2。对样本进行微拉伸粘结强度(µ TBS)测试,直至失效。使用单因素ANOVA(p = 0.05)计算统计分析。结果:平均µ TBS(MPa)为G1 = 22.27、G2 = 22.85和G3 = 20.3。经统计学分析,各组间无显著性差异。结论:通用粘合剂系统的性能与全蚀刻粘合剂相似,不受粘合策略的影响。关键词微拉伸;粘接系统;牙本质。
Objective : This study evaluated the microtensile bond strength of a universal adhesive system applied to deep dentin under different bonding strategies. Material and Methods : Fifteen human third molars had the coronal portion removed exposing deep dentin and were assigned into 3 groups according to the adhesive system: G1(control): 2-steps totaletch (Adper Single Bond 2, 3M ESPE); G2: 1-step self-etch universal adhesive (Scotchbond Universal, 3M ESPE); G3:2 steps total-etch universal adhesive (Scotchbond Universal, 3M ESPE). Composite buildups were performed on the dentin surfaces and after water storage for 24 h, teeth were sectioned to obtain 40 bonded beams per group with sectional area of 0.9 mm2 . The specimens were submitted to the microtensile bond strength (µTBS) test until failure. Statistical analyses were computed using one-way ANOVA (p = 0.05). Results : The mean µTBS (in MPa) were G1 = 22.27, G2 = 22.85 and G3 = 20.3. After statistical analysis, no significant differences were observed among the groups. Conclusions : Universal adhesive system performed similarly to the total-etch adhesive and was not affected by the adhesion strategy. KEYWORDS Microtensile; Adhesive system; Dentin.
