To investigate the clinical performance of a silorane-based composite resin used for repairing dimethacrylate- based composite restorations.
One operator repaired defective dimethacrylate-based resin restorations that were randomly assigned to one of two treatment groups: control (n=50), repaired with Adper SE Plus and Filtek P60 Posterior Restorative (3M ESPE); or test (n=50), repaired with P90 System Adhesive Self-Etch Primer and Bond and Filtek P90 Low Shrink Posterior Restorative (3M ESPE). After 1 week, restorations were finished and polished. Two calibrated examiners (weighted Kappa≥0.78) evaluated the repaired restorations, blindly and independently, at baseline, after 6 months, 1 and 2 years. The parameters examined were marginal adaptation, anatomic form, surface roughness, marginal discoloration, postoperative sensitivity, and secondary caries. The restorations were classified as Alfa, Bravo, or Charlie, according to modified US Public Health Service criteria. Variation in the levels of clinical parameters over time was evaluated by Friedman's ANOVA (α=0.05). The Mann-Whitney test assessed the differences between the materials for all clinical criteria at baseline, 6-month, 1- and 2-year recalls (α=0.05). The Wilcoxon test compared each composite resin for all clinical criteria at the same recalls (α=0.05).
After two years, 79 repaired restorations were re-examined. No statistically significant differences were found between the materials at baseline or at the 2-year recall (p>0.05). Comparing baseline and 2-year recall, there was a statistically significant difference for marginal discoloration (p=0.029) in silorane-based composite restorations.
After two years, the clinical performance of the silorane-based composite was similar to that of the dimethacrylate-based composite when used to make repairs.
研究一种用于修复双甲基丙烯酸酯基复合树脂修复体的硅氧烷基复合树脂的临床性能。
由一名操作人员修复有缺陷的双甲基丙烯酸酯基树脂修复体，这些修复体被随机分配到两个治疗组之一：对照组（n = 50），用Adper SE Plus和Filtek P60后牙修复材料（3M ESPE）修复；试验组（n = 50），用P90系统自酸蚀底漆和粘结剂以及Filtek P90低收缩后牙修复材料（3M ESPE）修复。1周后，对修复体进行修整和抛光。两名经过校准的检查人员（加权Kappa≥0.78）在基线、6个月、1年和2年后对修复后的修复体进行盲法独立评估。检查的参数包括边缘适应性、解剖形态、表面粗糙度、边缘变色、术后敏感性和继发龋。根据美国公共卫生服务标准的修订版，将修复体分为阿尔法、布拉沃或查理等级。通过Friedman方差分析评估临床参数水平随时间的变化（α = 0.05）。Mann-Whitney检验评估了在基线、6个月、1年和2年回访时所有临床标准下材料之间的差异（α = 0.05）。Wilcoxon检验比较了在相同回访时每种复合树脂的所有临床标准（α = 0.05）。
两年后，对79个修复后的修复体进行了重新检查。在基线或2年回访时，材料之间未发现统计学上的显著差异（p>0.05）。比较基线和2年回访时，硅氧烷基复合树脂修复体的边缘变色存在统计学上的显著差异（p = 0.029）。
两年后，当用于修复时，硅氧烷基复合树脂的临床性能与双甲基丙烯酸酯基复合树脂相似。
