Abstract

PURPOSE

To evaluate dentin sealing (DS), micropermeability (MP), and dentin bond strength (BS) of HEMA-free adhesives after 24 h and one year of artificial saliva storage.

MATERIALS AND METHODS

Two HEMA-free (G-ænial Bond and BeautiBond) and All-Bond 3 (the bottle of resin is HEMA-free) adhesives were tested. Adper Single Bond 2, a HEMA-containing adhesive, served as the control. All adhesives were applied according to the manufacturers' instructions and teeth were prepared for DS (n = 5), MP (n = 5), and BS testing (n = 10). DS under a pulpal pressure of 10 psi was performed at 4 time points (when smear layer was present, after EDTA treatment, after adhesive application, and after 1 year). MP was assessed using pulpal pressure of a 20-cm aqueous dye-solution column and confocal laser scanning microscopy. DS, MP, and BS were performed after 24 h or one-year storage. BS and DS data were statistically analyzed using two-way ANOVA, the Tukey-Kramer test (for BS) and Tukey's post-hoc test (for DS) (a = 0.05). A qualitative MP assessment was performed by comparing the accumulation of yellow dye within the resin-dentin interface.

RESULTS

Adper Single Bond 2 and All-Bond 3 completely sealed the dentin at 24 h and one year. G-ænial Bond showed statistically significant DS reduction of approximately 15% after one year. BeautiBond showed no DS reduction after one year. The resin-dentin interface created using Adper Single Bond 2 and GA showed dye accumulation primarily after one year. The mean BS of All-Bond 3 was statistically significantly higher than that of other adhesives, while G-ænial Bond and BeautiBond showed statistically significantly lower mean bond strengths than did Adper Single Bond 2 and All-Bond 3. After one-year storage, the mean BS was statistically significantly lower only for G-ænial Bond.

CONCLUSION

DS, MP, and BS were not influenced by the absence of HEMA in the tested adhesives.

摘要

目的

评估 24 小时和一年人工唾液储存后无 HEMA 胶粘剂的牙本质密封（DS）、微渗透性（MP）和牙本质结合强度（BS）。

材料和方法

测试了两种无 HEMA（G-ænial Bond 和 BeautiBond）和 All-Bond 3（树脂瓶无 HEMA）胶粘剂。Adper Single Bond 2，一种含 HEMA 的胶粘剂，作为对照。所有胶粘剂均按照制造商的说明使用，牙齿用于 DS（n = 5）、MP（n = 5）和 BS 测试（n = 10）。在 10 psi 的牙髓压力下进行 DS，共 4 个时间点（存在玷污层时、EDTA 处理后、胶粘剂应用后和 1 年后）。MP 使用 20-cm 水性染料溶液柱和共聚焦激光扫描显微镜的牙髓压力进行评估。24 小时或一年储存后进行 DS、MP 和 BS 测试。使用双向方差分析、Tukey-Kramer 检验（用于 BS）和 Tukey 的事后检验（用于 DS）（a = 0.05）对 BS 和 DS 数据进行统计分析。通过比较黄色染料在树脂-牙本质界面内的积累来进行定性的 MP 评估。

结果

Adper Single Bond 2 和 All-Bond 3 在 24 小时和一年时完全密封牙本质。G-ænial Bond 在一年后牙本质密封显著降低约 15%。BeautiBond 在一年后没有牙本质密封降低。使用 Adper Single Bond 2 和 GA 形成的树脂-牙本质界面在一年后主要出现染料积累。All-Bond 3 的平均 BS 明显高于其他胶粘剂，而 G-ænial Bond 和 BeautiBond 的平均结合强度明显低于 Adper Single Bond 2 和 All-Bond 3。储存一年后，只有 G-ænial Bond 的平均 BS 明显降低。
