Abstract

PURPOSE

To evaluate the microtensile bond strengths (microTBS) of 1-step vs. 2-step self-etch systems to dentin after 24 hours and after 6 months of water storage.

METHODS

Resin composite buildups were bonded to occlusal dentin of third molars using the following adhesives: Xeno IV (XE, Dentsply), G-Bond (GB, GC Inc), Clearfil S3 Bond (CS3, Kuraray); Adper Prompt L-Pop (AD, 3M ESPE); Go (GO, SDI), All Bond SE (ABSE 1-step or ABSE 2-step, Bisco) and Clearfil SE Bond (CSE, Kuraray). The bonded sticks (cross-sectioned area of 0.8-0.9 mm2) originated from the same teeth were randomly divided to be tested after 24 hours or after 6 months of water storage. The data was submitted to two-way repeated measures ANOVA and Tukey's test with and without the inclusion of premature failures (PF) (alpha = 0.05).

RESULTS

The inclusion of PF resulted in different statistically significant means for CS3, CSE and AD (P<0.05). Only the ABSE2 showed stable bonds after 6 months of water storage (P>0.05).

摘要

目的

评估一步法与两步法自酸蚀系统在储存24小时及储存6个月后的牙本质微拉伸粘结强度（microTBS）。

方法

使用以下粘结剂将树脂复合体堆积粘结到第三磨牙的咬合面牙本质上：Xeno IV（XE，登士柏公司）、G-Bond（GB，GC公司）、Clearfil S3 Bond（CS3，可乐丽公司）；Adper Prompt L-Pop（AD，3M ESPE公司）；Go（GO，SDI公司）、全粘结自酸蚀剂（ABSE一步法或ABSE两步法，碧施公司）和Clearfil SE Bond（CSE，可乐丽公司）。将来自同一颗牙齿的粘结棒（横截面面积为0.8 - 0.9平方毫米）随机分组，在储存24小时或储存6个月后进行测试。数据进行双向重复测量方差分析以及有无纳入早期失败（PF）情况的Tukey检验（α = 0.05）。
