The aim of this study was to evaluate the 5-year clinical performance of composite restorations of non-carious cervical lesions (NCCL) using a total-etch adhesive system with or without collagen removal with 10% sodium hypochlorite (NaOCl).
In this study randomized controlled split-mouth clinical trial, one-hundred and thirty-eight NCCL were restored into 30 patients. Each patient received at least one pair of composite restorations (Filtek A110/3M ESPE), bonded either with 2 techniques: Conventional Technique--acid etching with 37% phosphoric acid+Prime & Bond NT (Denstply DeTrey); Deproteinization Technique--acid etching with 37% phosphoric acid+10% NaOCl for 1min+Prime & Bond NT. The two techniques were evaluated using the United States Public Health Service (USPHS) criteria at baseline, 18 months, 3 and 5 years. After five years, one-hundred and six restorations were evaluated in 24 patients. Data were analyzed using the Chi-Square test (p<0.05).
There were no statistically significant differences between the two techniques regarding the evaluated parameters (p>0.05).
After 5 years, the application of 10% NaOCl deproteinization on etched dentine did not affect the clinical performance of composite restorations placed in NCCL when compared to the conventional total-etch technique.
Clinical studies evaluating the performance of the Deproteinization Technique are scarce. In this study, this technique showed similar clinical performance at the end of 5 years when compared to a conventional total-etch technique.
本研究旨在评估使用全酸蚀粘结系统，采用或不采用10%次氯酸钠（NaOCl）去除牙本质胶原的方法修复非龋性颈部病变（NCCL）复合树脂修复体的5年临床性能。
在这项随机对照的半口临床试验中，为30例患者的138个NCCL进行了修复。每位患者至少接受一对复合树脂修复体（Filtek A110/3M ESPE），采用两种技术进行粘结：传统技术——用37%磷酸酸蚀+Prime & Bond NT（登士柏德瑞）；去蛋白技术——用37%磷酸酸蚀+10% NaOCl处理1分钟+Prime & Bond NT。在基线、18个月、3年和5年时，使用美国公共卫生服务（USPHS）标准对这两种技术进行评估。5年后，对24例患者的106个修复体进行了评估。采用卡方检验分析数据（p<0.05）。
在评估参数方面，两种技术之间无统计学显著差异（p>0.05）。
5年后，与传统全酸蚀技术相比，在酸蚀牙本质上应用10% NaOCl去蛋白处理并不影响NCCL复合树脂修复体的临床性能。
评估去蛋白技术性能的临床研究较少。在本研究中，与传统全酸蚀技术相比，该技术在5年末显示出相似的临床性能。
