To evaluate the clinical success of posterior composite restorations repaired with and without silane application for up to 2 years.
In this retrospective study, patient record files acquired from the 40 patients who were treated due to needing repair for two class II defective composite restorations and visited the clinical practice for regular check-up visits were used. In the experimental group, the defective restorations were repaired using a silane coupling agent (Porcelain Primer), a universal adhesive (G-Premio Bond), and a microhybrid resin composite (Charisma Smart). In the control group, the restorations were repaired using the universal adhesive and the resin composite without silane coupling agent application. The repaired restorations were blindly assessed by two calibrated examiners using modified USPHS criteria at baseline, 6 months, 1, and 2 years. The data were analyzed using non-parametric tests (p = 0.05).
After 2 years, 80 repaired class II restorations were evaluated. No restoration of either the control or silane-treated group failed. After 2 years, there were no statistically significant differences between the experimental and control groups (p > 0.05). The differences in surface roughness were observed in each group over time (p < 0.05). There were no variations in other criteria over time (p > 0.05).
There was no significant effect of the silane coupling agent on restoration repair survival.
The repair of localized defects of the posterior composite restorations either with or without silane application is a conservative treatment option that may increase the clinical success of these restorations.
评估使用和不使用硅烷处理的后牙复合树脂修复体在长达 2 年的临床成功率。
在这项回顾性研究中，使用了从因需要修复两个 II 类缺损复合树脂而接受治疗并在临床实践中进行定期随访的 40 名患者的病历文件。在实验组中，使用硅烷偶联剂（瓷质底漆）、通用粘结剂（G-Premio Bond）和微混合树脂复合材料（Charisma Smart）修复有缺陷的修复体。在对照组中，使用通用粘结剂和不含硅烷偶联剂的树脂复合材料修复修复体。在基线、6 个月、1 年和 2 年时，由两名经过校准的检查者使用改良的 USPHS 标准对修复的修复体进行盲法评估。使用非参数检验（p = 0.05）对数据进行分析。
2 年后，评估了 80 个修复的 II 类修复体。对照组和硅烷处理组均无修复体失败。2 年后，实验组和对照组之间没有统计学差异（p > 0.05）。在每个组中，随着时间的推移，表面粗糙度都存在差异（p < 0.05）。随着时间的推移，其他标准没有变化（p > 0.05）。
硅烷偶联剂对修复体修复体的存活率没有显著影响。
无论是使用硅烷处理还是不使用硅烷处理的后牙复合树脂修复体的局部缺陷修复都是一种保守的治疗选择，可能会增加这些修复体的临床成功率。
