The aim of this randomized, controlled, prospective clinical trial was to evaluate the performances of two different universal adhesives and one etch-rinse adhesive for restoration of non-carious cervical lesions (NCCLs).
Twenty patients with at least seven NCCLs were enrolled. Lesions were divided into seven groups according to adhesive systems and application modes: GSE: GLUMA Universal-self-etch, GSL: GLUMA Universal-selective etching, GER: GLUMA Universal-etch-and-rinse, ASE: All-Bond Universal-self-etch, ASL: All-Bond Universal-selective etching, AER: All-Bond Universal-etch-and-rinse, SBE (Control): Single Bond2-etch-and-rinse. A total of 155 NCCLs were restored with a nano hybrid composite (Tetric N-Ceram). Restorations were scored with regard to retention, marginal discoloration, marginal adaptation, recurrent caries and post-operative sensitivity using modified United States Public Health Service (USPHS) criteria after one week, 6, 12 and 24 months. Statistical evaluations were performed using Chi-square tests (p=0.05).
The recall rate was 81.9% after the 24-month follow-up. The cumulative retention rates for self-etch groups (GSE: 72.2%, ASE:75%) were significantly lower than other experimental groups (GSL: 93.7%, GER: 100%, ASL: 94.1%, AER: 100%, SBE: 100%) at the 24-month follow-up (p<0.05). Regarding marginal adaptation and marginal discoloration, GSE and ASE groups demonstrated more bravo scores after 6 and 12-month observations but differences were not significant (p>0.05). Only one restoration from ASL group demonstrated post-operative sensitivity at 6 and 12-month observations. No secondary caries was observed on the restorations at any recall. At the end of 24-month observations, no significant differences were detected among groups regarding any of the criteria assessed, except retention.
GLUMA Universal and All-Bond Universal showed better results in etch-and-rinse and selective etching mode compared to the self-etch mode regarding retention. Etch-and-rinse and selective etching application modes of the current universal adhesives tended to provide better clinical outcomes considering the criteria evaluated at the end of 24-month evaluation.
本随机、对照、前瞻性临床试验旨在评估两种通用型黏结剂和一种自酸蚀黏结剂用于修复非龋性颈壁缺损（NCCLs）的性能。
共纳入 20 名至少有 7 处 NCCLs 的患者。根据黏结系统和应用方式将病变分为 7 组：GSE：GLUMA Universal 自酸蚀，GSL：GLUMA Universal 选择性酸蚀，GER：GLUMA Universal 酸蚀-冲洗，ASE：All-Bond Universal 自酸蚀，ASL：All-Bond Universal 选择性酸蚀，AER：All-Bond Universal 酸蚀-冲洗，SBE（对照）：Single Bond2 酸蚀-冲洗。使用纳米复合树脂（Tetric N-Ceram）共修复 155 处 NCCLs。在 1 周、6 个月、12 个月和 24 个月时，采用改良美国公共卫生服务（USPHS）标准评估保留率、边缘变色、边缘适合性、继发龋和术后敏感情况。采用卡方检验（p=0.05）进行统计学评估。
24 个月随访时的召回率为 81.9%。在 24 个月随访时，自酸蚀组（GSE：72.2%，ASE：75%）的累积保留率明显低于其他实验组（GSL：93.7%，GER：100%，ASL：94.1%，AER：100%，SBE：100%）（p<0.05）。关于边缘适合性和边缘变色，GSE 和 ASE 组在 6 个月和 12 个月观察时的 Bravo 评分较高，但差异无统计学意义（p>0.05）。只有 1 例 ASL 组的修复体在 6 个月和 12 个月观察时出现术后敏感。任何一次复诊时均未观察到继发龋。在 24 个月观察结束时，除保留率外，各组在其他评估标准方面均无显著差异。
与自酸蚀模式相比，GLUMA Universal 和 All-Bond Universal 在酸蚀-冲洗和选择性酸蚀模式下的保留效果更好。考虑到 24 个月评估结束时的评估标准，目前的通用型黏结剂的酸蚀-冲洗和选择性酸蚀应用模式更倾向于提供更好的临床效果。
