The aim of this study was to assess the clinical performance of a monoshade universal resin composite as posterior restoration. Twenty adult patients having at least two carious lesions related to posterior teeth were selected. Each patient was provided with a monoshade resin composite (Omnichroma) and polyshade nanohybrid resin composite (Tetric N-Ceram) for class I or II restorations. The performance of these restorations was assessed at 1, 3, 6, 9, and 12 months according to the modified United States Public Health Service (USPHS) criteria. Statistical analysis was carried out employing the Friedmann test and the Wilcoxon signed-rank test, with a significance level of p = 0.05. None of the restorations exhibited any clinical conditions warranting replacement. The monoshade universal group revealed prevalence of (Bravo) scores concerning the anatomic form, surface texture and post-operative sensitivity through the follow-up period (P = 0.317). For color match and color stability, the polyshade group revealed a statistically significantly higher incidence of (Alpha) scores after 9 and 12 months (P = 0.025). After 12-months of follow-up, the monoshade universal resin composite demonstrated satisfactory clinical performance. It can serve as a viable substitute for polyshade nanohybrid composite where chair side time is an essential concern.
本研究的目的是评估一种单色调通用树脂复合材料作为后牙修复体的临床性能。选择了20名至少有两颗后牙龋损的成年患者。为每位患者提供一种单色调树脂复合材料（Omnichroma）和一种多色调纳米混合树脂复合材料（Tetric N-Ceram）用于Ⅰ类或Ⅱ类修复。根据改良的美国公共卫生服务（USPHS）标准，在1、3、6、9和12个月时评估这些修复体的性能。采用Friedmann检验和Wilcoxon符号秩检验进行统计分析，显著性水平为p = 0.05。所有修复体均未出现任何需要更换的临床情况。单色调通用组在随访期间关于解剖形态、表面纹理和术后敏感性的（Bravo）评分患病率为（P = 0.317）。对于颜色匹配和颜色稳定性，多色调组在9个月和12个月后（Alpha）评分的发生率在统计学上显著更高（P = 0.025）。经过12个月的随访，单色调通用树脂复合材料表现出令人满意的临床性能。在椅旁时间是一个重要问题的情况下，它可以作为多色调纳米混合复合材料的可行替代品。
