To evaluate the clinical performance of Scotchbond Universal (3M Oral Care) and Prime & Bond Elect (Dentsply Sirona) in the restoration of noncarious cervical lesions (NCCLs).
This was a randomized controlled clinical trial involving 63 subjects. Two hundred and three NCCLs were restored using Scotchbond Universal and Prime & Bond Elect using both an etch-and-rinse and a self-etch technique. Lesions were notch-shaped NCCLs, and the restorations were placed without any mechanical retention. Restorations were finished immediately after placement and scored with regard to retention, marginal discoloration, marginal adaptation, and secondary caries. Similar assessment of the restorations was performed 18 months after placement. Logistic regression was performed for each outcome separately with a compound symmetric variance-covariance structure assumed to consider a correlation of restorations within subjects. All analyses were conducted using SAS version 9.4 (SAS Inc).
One hundred and fifty-eight teeth (77.8% of the restorations placed) in 46 subjects (73% of subjects enrolled) were available for the 18-month follow-up. A statistically significant difference was reached only for the comparison Scotchbond Universal/self-etch (SU_SE) and Prime & Bond Elect/etch-and-rinse (PBE_E&R) groups ( p=0.01), where a restoration with SU_SE was 66% less likely to maintain a score of Alpha for marginal discoloration than a restoration performed with PBE_E&R.
Scotchbond Universal and Prime & Bond Elect presented acceptable clinical performance after 18 months of clinical service. However, Scotchbond Universal, when applied with a self-etch approach, did demonstrate a relatively high level of marginal discoloration when compared to the other groups.
评估通用型Scotchbond（3M口腔护理产品）和Prime & Bond Elect（登士柏西诺德公司）在非龋性颈部病变（NCCLs）修复中的临床性能。
这是一项随机对照临床试验，涉及63名受试者。使用通用型Scotchbond和Prime & Bond Elect通过酸蚀冲洗技术和自酸蚀技术修复了203个NCCLs。病变为缺口状NCCLs，修复体放置时未采用任何机械固位。修复体放置后立即完成，并根据固位、边缘变色、边缘适应性和继发龋进行评分。放置18个月后对修复体进行类似评估。对每个结果分别进行逻辑回归分析，假设采用复合对称方差协方差结构以考虑受试者体内修复体的相关性。所有分析均使用SAS 9.4版（SAS公司）进行。
46名受试者（占入组受试者的73%）中的158颗牙齿（占所放置修复体的77.8%）可进行18个月的随访。仅在通用型Scotchbond/自酸蚀（SU_SE）组和Prime & Bond Elect/酸蚀冲洗（PBE_E&R）组的比较中达到了统计学显著差异（p = 0.01），其中采用SU_SE修复的修复体边缘变色保持为Alpha评分的可能性比采用PBE_E&R修复的修复体低66%。
通用型Scotchbond和Prime & Bond Elect在临床应用18个月后表现出可接受的临床性能。然而，与其他组相比，通用型Scotchbond采用自酸蚀方法应用时，确实表现出相对较高水平的边缘变色。
