: The aim of this randomized split-mouth study-controlled clinical trial was to compare the 2-year clinical performance of resin composite restorations placed at non-caries cervical lesions (NCCL) with one-step self-etch, total-etch, and selective enamel etch and self-etch adhesive techniques. : Thirty-two patients received three resin composite restorations each at NCCLs (Tetric EvoCeram/Ivoclar/Vivadent), bonded with a total-etch adhesive agent (ExciTE F/Ivoclar/Vivadent) and a self-etch (AdheSE One F/Ivoclar/Vivadent) without and with selective enamel etching. All restorations were evaluated by two examiners at baseline, 6-, 12-, 18-, and 24-months with FDI clinical criteria (post-operation regarding retention, caries occurrence, marginal adaptation, and marginal staining). A logistic regression analysis, a Cohen's kappa statistic, a multifactorial analysis, and X were performed with generalized estimating equations. : After 2 years, the retention rate was 86.8% for total etch, 92.26% for self-etch, and 93.63% for selective enamel etching and self-etch. No caries was detected on the restorations. Concerning marginal adaptation, the clinically perfect restorations were 26.9% for the total-etch technique, 16% for self-etch, and 25.9% for selective enamel etch and self-etch. The logistic regression model revealed that only time reduced the probability of perfect marginal adaptation. : All three adhesive strategies provided restorations with no significant differences in the retention rate or marginal adaptation, whereas the total etch yielded better performance for marginal staining. All restorations were assessed as clinically acceptable after 2 years.
本随机分组、分侧、对照临床试验旨在比较非龋性颈缘缺损（NCCL）中应用一步法自酸蚀、全酸蚀、选择性酸蚀+自酸蚀及全酸蚀粘结技术的树脂复合材料修复体 2 年的临床性能。32 名患者的 NCCL 共接受 3 次树脂复合材料修复，粘结剂分别为全酸蚀粘结剂（ExciTE F/Ivoclar/Vivadent）和自酸蚀粘结剂（AdheSE One F/Ivoclar/Vivadent），其中后者有无选择性酸蚀。所有修复体在基线、6、12、18 和 24 个月时均由两位检查者使用 FDI 临床标准（修复后保留情况、继发龋、边缘适合性和边缘着色）进行评估。采用逻辑回归分析、Cohen's kappa 统计、多因素分析和卡方检验进行统计学分析，使用广义估计方程。2 年后，全酸蚀组的保留率为 86.8%，自酸蚀组为 92.26%，选择性酸蚀+自酸蚀组为 93.63%。修复体上均未发现继发龋。关于边缘适合性，全酸蚀组临床完美修复体为 26.9%，自酸蚀组为 16%，选择性酸蚀+自酸蚀组为 25.9%。逻辑回归模型表明，只有时间降低了完美边缘适合性的可能性。三种粘结策略在保留率或边缘适合性方面均无显著差异，而全酸蚀在边缘着色方面表现更好。所有修复体在 2 年后均被评估为临床可接受。
