The purpose of the present prospective and randomized clinical trial was to evaluate the clinical performance of noncarious cervical lesions (NCCLs) restored with different adhesion strategies on the dental substrate.
An adhesive restorative system (Single Bond Universal/ Z350XT) with and without selective enamel conditioning was evaluated, as well as a resin-modified glass-ionomer cement (Vitremer), with and without pretreatment with ethylenediaminetetraacetic acid (EDTA). Two operators placed a total of 200 restorations in 50 patients (four restorations per patient). Data from decayed, missing, and filled teeth (DMFT), visible plaque, and gingival bleeding were collected prior to the restorations and at each evaluation time. All restorations were evaluated using the modified United States Public Health Service (USPHS) evaluation system at baseline, and at 6 and 12 months. Data were analyzed by the Friedman, chi-square, Cochran, Wilcoxon, and multiple logistic regression analysis tests (P ≤ .05).
There was a gradual and significant increase in DMFT with a difference among the three evaluations (P ≤ .001). There was no difference for the Visible Plaque Index over time (P = .28); however, there was a significant reduction in the Gingival Bleeding Index between the baseline and the other evaluations (P ≤ .001). There was no statistically significant difference among groups and periods of evaluations (P > .05). Regarding logistic regression, the model as a whole was statistically significant (P = .034).
The four different adhesion strategies in the NCCL restorations presented similar clinical performance after 1 year of follow-up.
本前瞻性随机临床试验的目的是评估在牙体组织上采用不同粘结策略修复非龋性颈部病变（NCCL）的临床性能。
评估了一种粘结修复系统（单键通用型/Z350XT），有无选择性釉质预处理，以及一种树脂改性玻璃离子水门汀（Vitremer），有无乙二胺四乙酸（EDTA）预处理。两名操作人员在50名患者中总共放置了200个修复体（每位患者4个修复体）。在修复前以及每次评估时收集龋失补牙数（DMFT）、可见菌斑和牙龈出血的数据。所有修复体在基线时以及6个月和12个月时使用改良的美国公共卫生服务（USPHS）评估系统进行评估。数据通过Friedman检验、卡方检验、Cochran检验、Wilcoxon检验和多元逻辑回归分析检验进行分析（P≤0.05）。
DMFT有逐渐且显著的增加，三次评估之间存在差异（P≤0.001）。可见菌斑指数随时间无差异（P = 0.28）；然而，基线与其他评估之间牙龈出血指数有显著降低（P≤0.001）。各评估组和评估期之间无统计学显著差异（P>0.05）。关于逻辑回归，整个模型具有统计学显著性（P = 0.034）。
NCCL修复体中的四种不同粘结策略在随访1年后表现出相似的临床性能。
