To evaluate the clinical performance of a packable composite resin (Tetric Ceram HB) for posterior restorations of children after 3.5 years, according to Ryge criteria.
Twenty five open apex molar teeth with extensive caries in 21 Iranian patients (8.2 year mean age) were restored by one operator. After caries removal, a layer of calcium hydroxide and glass ionomer base, Fuji II LC were applied. The teeth were restored using an adhesive system, Excite, and flowable composite, Tetric-Flow. The cavities were then restored incrementally with a Tetric Ceram HB. All the 25 restorations were evaluated after 3.5 years by two independent evaluators. Statistical analysis was performed using McNemar test.
Surface texture for all restorations was classified as excellent. There were no evidence of secondary caries and bulk fracture in any of the restorations. Regarding the items of anatomical form and marginal integrity the statistical analysis reveled a significant difference between the baseline and recall scores respectively (P=0.031 and P=0.031).
It was concluded that Tertic Ceram HB exhibited excellent clinical performance after 3.5 years in the open apex first permanent molar teeth.
根据赖格标准,评估一种可压实复合树脂(Tetric Ceram HB)在3.5年后用于儿童后牙修复的临床性能。
21名伊朗患者(平均年龄8.2岁)的25颗开放性根尖磨牙有广泛龋坏,由一名操作者进行修复。去除龋坏组织后,应用一层氢氧化钙和玻璃离子垫底材料富士II LC。使用粘结系统Excite和流动复合树脂Tetric-Flow对牙齿进行修复。然后用Tetric Ceram HB逐层填充窝洞。3.5年后,由两名独立评估者对所有25个修复体进行评估。采用麦克尼马尔检验进行统计分析。
所有修复体的表面质地均评为优秀。所有修复体均未发现继发龋和大块折断的迹象。关于解剖形态和边缘完整性项目,统计分析显示基线评分和复查评分之间分别存在显著差异(P = 0.031和P = 0.031)。
得出结论,Tertic Ceram HB在开放性根尖第一恒磨牙中3.5年后表现出优异的临床性能。
