Abstract

OBJECTIVE

To test the influence of a hydrophobic resin coating (HC) on the immediate (24h) and 6-month (6m) microtensile dentin bond strengths (μTBS) and nanoleakage (NL) of three universal adhesives applied in self-etch (SE) or in etch-and-rinse (ER) mode.

METHODS

Sixty caries-free extracted third molars were assigned to 12 experimental groups resulting from the combination of the factors "adhesive system" (Scotchbond Universal Adhesive [SBU], 3M ESPE; All-Bond Universal [ABU], Bisco Inc.; and G-Bond Plus [GBP], GC Corporation); "adhesive strategy" (SE or ER); "hydrophobic resin coating" [HC] (with or without Heliobond, Ivoclar Vivadent); and "storage time" (24h or 6m). Specimens were prepared for μTBS testing - (24h) half of the beams were immediately tested under tension; and (6m) the other half was stored in distilled water (37°C) for 6m prior to testing. For each tooth, two beams were randomly selected for NL evaluation for both evaluation times. Data were analyzed for each adhesive system using three-way ANOVA and Tukey's post-hoc test (α=0.05).

RESULTS

μTBS: (24h): In SE mode, HC resulted in statistically greater mean μTBS for all adhesives. (6m): When HC was not used the mean μTBS for SBU/ER, ABU/ER, GBP/ER and SBU/SE decreased significantly. NL: (24h): SBU/ER, ABU/ER and GBP/SE resulted in a significant reduction in NL when HC was applied. (6m): No significant reduction was observed for SBU/ER or for SBU/SE regardless of the use of HC.

SIGNIFICANCE

The application of a hydrophobic resin coating improved the 24h and the 6m performances of all three adhesives systems in SE mode.

摘要

目的

测试疏水性树脂涂层（HC）对三种通用型胶粘剂在自酸蚀（SE）或酸蚀-冲洗（ER）模式下即刻（24h）和 6 个月（6m）微拉伸牙本质粘结强度（μTBS）和纳米渗漏（NL）的影响。

方法

将 60 颗无龋第三磨牙分为 12 个实验组，这些组来自以下因素的组合：“粘结剂系统”（Scotchbond Universal Adhesive [SBU]，3M ESPE；All-Bond Universal [ABU]，Bisco Inc.；和 G-Bond Plus [GBP]，GC Corporation）；“粘结剂策略”（SE 或 ER）；“疏水性树脂涂层”[HC]（带或不带 Heliobond，Ivoclar Vivadent）；和“储存时间”（24h 或 6m）。为 μTBS 测试制备标本-（24h）一半的梁立即在张力下进行测试；（6m）另一半在测试前在蒸馏水中（37°C）储存 6m。对于每颗牙齿，从每个牙上随机选择两个梁进行即刻和 6m 时的 NL 评估。使用三因素方差分析和 Tukey 事后检验（α=0.05）对每种粘结剂系统的数据进行分析。

结果

μTBS：（24h）：在 SE 模式下，HC 导致所有粘结剂的平均 μTBS 均有统计学上的显著增加。（6m）：当不使用 HC 时，SBU/ER、ABU/ER、GBP/ER 和 SBU/SE 的平均 μTBS 显著降低。NL：（24h）：当使用 HC 时，SBU/ER、ABU/ER 和 GBP/SE 的 NL 显著降低。（6m）：无论是否使用 HC，SBU/ER 或 SBU/SE 均未观察到显著降低。
