Abstract The aim of this study was to evaluate if acid etching prior to application of different universal adhesives influences the bond strength of the glass fiber post to root dentin. One hundred and twenty (120) bovine-tooth roots were prepared to receive glass fiber posts #3 (White Post, FGM) and then divided into 12 groups (n = 10) according to two factors: the adhesive system (Single Bond Universal, Ambar Universal, Prime & Bond Universal, Gluma Bond Universal, YBond Universal or Ambar Universal APS); and acid etching prior to application of the adhesive (presence or absence). After cementation, the specimens were stored in a humid environment at 37°C for 24 hours. Each sample was sectioned into 5 slices with 1.5 ± 0.2 mm thickness and subjected to a pushout test with an increasing load of 1 mm/min in a universal testing machine until failure and the data were analyzed using two-way ANOVA and post-hoc Tukey’s tests. There was no statistical difference in the bond strength values for the acid etching factor. There were only differences for the adhesive system factor. Higher bond strength values were found for the Universal Single Bond adhesive (3M) regardless of acid etching or not, and for Gluma Bond Universal adhesive without acid etching. It was possible to conclude that acid etching prior to applying the universal adhesives used in this study does not influence the bond strength of glass fiber posts to root dentin.

在使用通用粘合剂之前进行酸蚀是否会影响玻璃纤维桩与根牙本质的粘合强度？

摘要 本研究的目的是评估在使用不同通用粘合剂之前进行酸蚀是否会影响玻璃纤维桩与根牙本质的粘合强度。准备一百二十 (120) 个牛牙根以接收玻璃纤维桩 #3 (White Post, FGM)，然后根据两个因素分为 12 组 (n = 10)：粘合剂系统（Single Bond Universal， Ambar Universal、Prime & Bond Universal、Gluma Bond Universal、YBond Universal 或 Ambar Universal APS）；以及在使用粘合剂（存在或不存在）之前进行酸蚀刻。胶结后，将试样在 37°C 的潮湿环境中保存 24 小时。每个样品以 1.5 ± 0 被切成 5 个切片。2 毫米厚，​​并在万能试验机中以 1 毫米/分钟的增加载荷进行推出试验，直至失效，数据使用双向方差分析和事后 Tukey 测试进行分析。酸蚀刻因子的结合强度值没有统计学差异。仅有粘合剂系统因素的差异。无论是否进行酸蚀刻，Universal Single Bond 粘合剂 (3M) 和无酸蚀刻的 Gluma Bond Universal 粘合剂都具有更高的粘合强度值。可以得出结论，在使用本研究中使用的通用粘合剂之前进行酸蚀不会影响玻璃纤维桩与根牙本质的粘合强度。酸蚀刻因子的结合强度值没有统计学差异。仅有粘合剂系统因素的差异。无论是否进行酸蚀刻，Universal Single Bond 粘合剂 (3M) 和无酸蚀刻的 Gluma Bond Universal 粘合剂都具有更高的粘合强度值。可以得出结论，在使用本研究中使用的通用粘合剂之前进行酸蚀不会影响玻璃纤维桩与根牙本质的粘合强度。酸蚀刻因子的结合强度值没有统计学差异。仅有粘合剂系统因素的差异。无论是否进行酸蚀刻，Universal Single Bond 粘合剂 (3M) 和无酸蚀刻的 Gluma Bond Universal 粘合剂都具有更高的粘合强度值。可以得出结论，在使用本研究中使用的通用粘合剂之前进行酸蚀不会影响玻璃纤维桩与根牙本质的粘合强度。
