To evaluate non-carious cervical lesions (NCCLs) restored with different adhesion strategies.
This is a prospective, randomized, double-blind, split-mouth study. An adhesive restorative system (Single Bond Universal/Filtek Z350XT - SBU) was evaluated both without and with selective enamel conditioning (E-SBU), resin-modified glass-ionomer cements (Vitremer; RMGIC), and ethylenediaminetetraacetic acid pretreatment (EDTA; E-RMGIC). In total, 200 restorations, placed in 50 patients, were evaluated at baseline and at a 3-year follow-up using the modified United States Public Health Service (USPHS) criteria. Data were analyzed using the two-proportion equality test, multinomial logistic regression, Wilcoxon test, and Kaplan-Meier survival curves.
In total, 42 (84%) patients returned for the 3-year follow-up. SBU showed restoration losses statistically different from RMGIC. Retention was also statistically different in SBU between baseline and the 3-year follow-up. Marginal defects and surface texture were statistically significant for all groups in the period studied, except for the surface texture of SBU and the marginal integrity in E-RMGIC. We observed no statistically significant difference in wear, secondary caries, anatomical form, surface staining, and color over time. Recession degree was the only factor to influence retention rates. Cumulative survival (%) was 89, 98, 98, and 95.3, for SBU, SE-SBU, RMGIC, and E-RMGIC, respectively, without significant differences among them. There was a statistically significant difference between survival curves; however, multiple comparison procedures found no statistical differences.
Selective enamel etching affected the retention of non-carious cervical restorations. Adhesion using EDTA and resin-modified glass-ionomer cements delayed marginal defects over time. The degree of gingival recession influenced retention rates. Resin composite restorations showed initial marginal defects, and ionomer restorations, reduced surface luster. EDTA pre-treatment followed by resin-modified glass-ionomer cements may be a promising adhesion strategy for NCCL restorations.
评估采用不同粘结策略修复非龋性颈领缺损（NCCLs）的效果。
这是一项前瞻性、随机、双盲、分口研究。评估了一种粘结修复系统（Single Bond Universal/Filtek Z350XT - SBU），分别在不进行选择性釉质酸蚀（E-SBU）和进行选择性釉质酸蚀、树脂改良型玻璃离子水门汀（Vitremer；RMGIC）及乙二胺四乙酸预处理（EDTA；E-RMGIC）的情况下的效果。共在 50 名患者的 200 个修复体上进行了研究，在基线和 3 年随访时使用改良美国公共卫生服务（USPHS）标准进行评估。使用两比例相等检验、多项逻辑回归、Wilcoxon 检验和 Kaplan-Meier 生存曲线对数据进行分析。
共有 42 名（84%）患者完成了 3 年随访。SBU 的修复体丧失情况与 RMGIC 相比具有统计学差异。SBU 的保留情况在基线和 3 年随访时也存在统计学差异。在研究期间，所有组的边缘缺陷和表面质地均具有统计学意义，但 SBU 的表面质地和 E-RMGIC 的边缘完整性除外。我们未观察到随时间推移，在磨损、继发龋、解剖形态、表面着色和颜色方面有统计学意义的差异。牙龈退缩程度是影响保留率的唯一因素。累积存活率（%）分别为 SBU 89、SE-SBU 98、RMGIC 98 和 E-RMGIC 95.3，各组之间无统计学差异。生存曲线之间存在统计学差异；然而，多重比较程序发现无统计学差异。
选择性釉质酸蚀影响非龋性颈领修复体的保留情况。使用 EDTA 和树脂改良型玻璃离子水门汀会随时间推移延迟边缘缺陷的出现。牙龈退缩程度影响保留率。树脂复合材料修复体出现初始边缘缺陷，而离聚物修复体的表面光泽度降低。EDTA 预处理后再使用树脂改良型玻璃离子水门汀可能是 NCCL 修复的一种有前途的粘结策略。
