摘要
目的:本研究的目的是评估一年后可包装和低收缩率的甲基丙烯酸酯基复合材料的临床性能。材料和方法:在本临床试验中,25例患者放置50个I或II级修复体。每位患者接受两次修复。测试材料为:(I) Filtek P60 + Single Bond 2和(II) Kalore GC + Single Bond 2。根据修改后的美国公共卫生局(USPHS)标准,由两名独立检查员在一周(基线)、六个月和一年后对修复体进行评估。评估参数包括颜色匹配、边缘适应、解剖形态、保留、表面纹理、术后敏感性、边缘染色和继发龋。结果:P60和Kalore在6个月和1年时的表现相似(P>0.05)。当每种复合树脂在基线和一年后独立评估时,除了边缘适应(P60)外,没有发现统计学上显著的差异,其中四个修复体被评为Bravo(临床可接受)。在8%的修复体中,患者表示术后敏感。结论:Kalore GC和Filtek P60在使用一年后临床表现良好。
One Year Clinical Evaluation of a Low Shrinkage Composite Compared with a Packable Composite Resin: A Randomized Clinical Trial.
Objectives: The aim of this study was to evaluate the clinical performance of a packable and a low shrinkage methacrylate-based composite after one year.
Materials and methods: In this clinical trial, 50 class I or II restorations were placed in 25 patients. Each patient received two restorations. The tested materials were: (I) Filtek P60 + Single Bond 2 and (II) Kalore GC + Single Bond 2. The restorations were evaluated by two independent examiners after one week (baseline), six months and one year according to the modified United States Public Health Service (USPHS) criteria. The evaluated parameters included color match, marginal adaptation, anatomical form, retention, surface texture, postoperative sensitivity, marginal staining and secondary caries. Data were then analyzed using Friedman and conditional (matched) logistic regression tests at P<0.05 level of significance.
Results: P60 and Kalore performed similarly at six months and one year (P>0.05). When each composite resin was evaluated independently at baseline and after one year, no statistically significant differences were found except for marginal adaptation (P60) where four restorations were rated Bravo (clinically acceptable). In 8% of restorations, patients expressed postoperative sensitivity.
Conclusions: Kalore GC and Filtek P60 showed acceptance clinical performance after one year of service.
