To evaluate and compare the shear bond strength (SBS) of Embrace WetBond (EWS) Pit and Fissure Sealant (PF sealants) with or without the use of a universal dental adhesive system Scotchbond Universal Adhesive (SBU) using different bonding and curing protocols and to assess and compare the mode of failure as determined by visualization of the fractured surfaces of the test specimens after shear testing under an optical microscope at a magnification of 20×.
A total of 85 samples were prepared for testing SBS on enamel on caries-free, extracted permanent human molars. The specimens were randomly divided into five groups based on different bonding and curing protocols. A knife-edge blade in a universal testing machine was used to perform the SBS test with a crosshead speed of 1 mm/minute. Then the mode of failure was assessed.
Results were analyzed using a one-way analysis of variance with Tukey's test and Chi-squared test. A probability value 0.05 ( ≤ 0.01) was regarded as significant.
Scotchbond Universal Adhesive (SBU) in total-etch (TE) mode/etch-and-rinse (ER) mode with individual light curing of the sealant and adhesive showed the highest SBS to enamel (5.40 ± 2.51 MPa). A predominance of cohesive mode of failure was observed for all the test groups.
Embrace WetBond (EWS) PF sealants with SBU in the ER mode of application, with either curing mode, can be used as an alternative to a conventional technique for sealant placement for improving interfacial bond strength to enhance sealant retention and efficacy.

评估和比较使用或不使用通用牙科粘结系统Scotchbond Universal Adhesive(SBU)的Embrace WetBond(EWS)窝沟封闭剂(PF封闭剂)在不同粘结和固化方案下的剪切粘结强度(SBS),并通过在光学显微镜下以20倍放大率观察剪切测试后试样断裂表面来评估和比较失效模式。
总共制备了85个样本,用于在无龋的拔除恒牙磨牙的牙釉质上测试SBS。根据不同的粘结和固化方案,将试样随机分为五组。使用万能试验机中的刀口刀片以1毫米/分钟的十字头速度进行SBS测试。然后评估失效模式。
结果采用单因素方差分析、Tukey检验和卡方检验进行分析。概率值0.05(≤0.01)被视为具有统计学意义。
在全酸蚀(TE)模式/酸蚀冲洗(ER)模式下,单独对封闭剂和粘结剂进行光固化的Scotchbond Universal Adhesive(SBU)对牙釉质的SBS最高(5.40±2.51兆帕)。所有测试组均观察到主要为内聚性失效模式。
在ER应用模式下,无论采用何种固化模式,使用SBU的Embrace WetBond(EWS)PF封闭剂可作为传统封闭剂放置技术的替代方法,以提高界面粘结强度,增强封闭剂的保留率和效果。
