To compare the clinical performance of a universal adhesive in class V non-carious cervical lesions (NCCLs) using two surface treatment protocols (self-etch [SfE] vs selective-enamel-etch [SelE]).
Thirty-three adults, each with ≥2 NCCLs, received one resin composite restoration utilizing a SfE universal adhesive and another utilizing the adhesive and SelE with 37% phosphoric acid. Restorations were evaluated for sensitivity, retention, marginal discoloration, marginal adaptation, and clinical acceptability through 24 months using Cochran-Mantel-Haenszel tests for stratified, ordered categorical outcomes.
Sixty-six restorations (35 SfE, 31 SelE; 27 volunteers) were evaluated at 24 months. There were no significant differences between SfE and SelE for sensitivity, retention, marginal adaptation, or clinical acceptability. One SfE restoration was lost. Marginal adaptation was significantly worse at 24 months than baseline for SelE (P = 0.01), but not for SfE. Marginal discoloration was significantly worse for SfE (P = 0.02), but not for SelE. Sensitivity improved from baseline to 24 months for both groups (SelE P = 0.004, SfE P = 0.002).
Twenty-four-month data indicated significantly reduced sensitivity for both groups, worse marginal discoloration for SfE, and worse marginal adaptation for SelE. No changes in retention or clinical acceptability were observed in either group. All retained restorations were clinically acceptable at 24 months.
Both self-etch and selective enamel etch techniques with a universal adhesive produced clinically acceptable results in resin composite restorations for NCCLs over 2 years.
比较通用粘结剂在 V 类非龋性颈（牙合）面缺损（NCCLs）中的临床性能，使用两种表面处理方案（自酸蚀 [SfE] 与选择性釉质酸蚀 [SelE]）。
33 名成年人，每人至少有 2 个 NCCLs，分别用 SfE 通用粘结剂和含 37%磷酸的粘结剂与 SelE 处理后进行树脂复合材料修复。通过 Cochran-Mantel-Haenszel 检验对分层有序分类结局进行 24 个月的敏感性、保留率、边缘变色、边缘适应性和临床可接受性评估。
66 个修复体（35 个 SfE，31 个 SelE；27 名志愿者）在 24 个月时进行评估。SfE 和 SelE 在敏感性、保留率、边缘适应性或临床可接受性方面均无显著差异。有 1 个 SfE 修复体丢失。SelE 的边缘适应性在 24 个月时显著差于基线（P = 0.01），而 SfE 则不然。SfE 的边缘变色显著差于 SelE（P = 0.02），但 SelE 则不然。两组的敏感性均从基线改善到 24 个月（SelE P = 0.004，SfE P = 0.002）。
24 个月的数据表明，两组的敏感性均显著降低，SfE 的边缘变色更差，SelE 的边缘适应性更差。两组均未观察到保留率或临床可接受性的变化。所有保留的修复体在 24 个月时均具有临床可接受性。
在 2 年以上的 NCCLs 树脂复合材料修复中，自酸蚀和选择性釉质酸蚀技术联合通用粘结剂均可获得临床可接受的效果。
