摘要

这项体外研究旨在评估树脂改性玻璃离子粘合剂的修复粘接强度,在蚀刻-冲洗和自酸蚀模式下使用相同的材料或通用粘合剂,再加上树脂复合材料。将二十四块树脂改性玻璃离子粘合剂砌块在蒸馏水中存放 14 天后进行热循环。根据修复方案将砂纸磨碎的试样随机分配到三个实验组:蚀刻-冲洗或自酸蚀模式下的树脂改性玻璃离子水泥(Riva Light Cure,SDI)和通用粘合剂(Scotchbond Universal Adhesive,3M Oral Care)以及纳米混合树脂复合材料(Z350 XT,3M Oral Care)。贮水 24 小时后,对牙块进行切片,并对粘接棒进行微拉伸粘接强度(μTBS)测试。数据分析采用单因素方差分析和 Tukey 检验。对失效模式进行了描述性分析。当使用相同的材料修复树脂改性玻璃离子粘固剂时,μTBS 值最高(p < 0.01)。此外,通用粘合剂系统的应用方式并不影响树脂改性玻璃离子粘合剂的修复粘接强度。粘合剂/混合失败在所有组别中均占多数。用相同的材料修复树脂改性玻璃离聚体似乎是提高粘接强度的首选方案。

Restoration-repair potential of resin-modified glass ionomer cement.

This in vitro study aimed to evaluate the repair bond strength of resin-modified glass ionomer cement using either the same material or a universal adhesive in the etch-and-rinse and self-etch modes plus resin composite. Twenty-four resin-modified glass ionomer cement blocks were stored in distilled water for 14 d and thermocycled. Sandpaper ground specimens were randomly assigned to three experimental groups according to the repair protocol: resin-modified glass ionomer cement (Riva Light Cure, SDI) and universal adhesive (Scotchbond Universal Adhesive, 3M Oral Care) in etch-and-rinse or self-etch modes and nanohybrid resin composite (Z350 XT, 3M Oral Care). After 24 h of water storage, the blocks were sectioned, and bonded sticks were subjected to the microtensile bond strength (μTBS) test. One-way ANOVA and Tukey's test were used to analyze the data. The failure mode was descriptively analyzed. The highest μTBS values were obtained when the resin-modified glass ionomer cement was repaired using the same material (p < 0.01). In addition, the mode of application of the universal adhesive system did not influence the repair bond strength of the resin-modified glass ionomer cement. Adhesive/mixed failures prevailed in all groups. Repair of resin-modified glass ionomers with the same material appears to be the preferred option to improve bond strength.
