To evaluate the performance of All Bond SE used in a one- or two-step protocol in a 24-month randomized clinical study.
Thirty-three patients with two similarly sized non-carious cervical lesions participated in this study. A total of 66 restorations were placed, half using the one-step All Bond SE protocol (SE-1) and the other half using the two-step All Bond SE protocol (SE-2). The restorations were evaluated at baseline and after 6, 12 and 24 months following the modified USPHS criteria and analyzed by the McNemar's test and Fisher's exact test (alpha = 0.05).
After 24 months, six SE-1 and four SE-2 restorations were rated as Bravo in marginal discoloration The retention rates for SE-1 and SE-2 were 84.8% and 90.9%, respectively, after 24 months. Compared to baseline, the retention rate for SE-1 was statistically lower.
All Bond SE used in the one- or two-step protocol resulted in high retention rates after 24 months.
在一项为期 24 个月的随机临床试验中，评估 All Bond SE 在一步法或两步法方案中的性能。
33 名患有两个大小相似的非龋性颈前病变的患者参与了这项研究。共放置了 66 个修复体，一半使用一步法 All Bond SE 方案（SE-1），另一半使用两步法 All Bond SE 方案（SE-2）。根据改良的 USPHS 标准，在基线时以及治疗后 6、12 和 24 个月对修复体进行评估，并通过 McNemar 检验和 Fisher 确切概率检验（alpha = 0.05）进行分析。
24 个月后，6 个 SE-1 和 4 个 SE-2 修复体在边缘变色方面被评为 Bravo。SE-1 和 SE-2 的保留率分别为 84.8%和 90.9%，在 24 个月后。与基线相比，SE-1 的保留率统计学上较低。
All Bond SE 在一步法或两步法方案中使用，在 24 个月后具有较高的保留率。
