The aim of this study was to compare the 2-year clinical performance of a bulk-fill composite resin and a nano-hybrid-filled composite resin in 6-12-year-old children in a split-mouth design.
This randomized, split-mouth, and double-blind study was conducted on 89 patients aged 6-12 years with caries on bilateral mandibular first molars. In a split-mouth design, restorations of mandibular permanent molars were completed with nano-hybrid organically modified ceramic (ORMOCER)-based bulk-fill composite resin Admira Fusion x-tra (Voco GmbH, Cuxhaven, Germany) and nano-hybrid composite Grandio (Voco, Cuxhaven, Germany). Futurabond U single dose (Voco, Cuxhaven, Germany) was used with selective enamel etching. The clinical success of the restorations was evaluated using USPHS and FDI criteria at 6, 12, and 24-month follow-up controls.
In the 2-year follow-up, all restorations were clinically acceptable. Grandio was significantly worse than Admira Fusion x-tra in terms of surface luster and superficial change (p < 0.05). Surface staining and color match scores increased in Admira Fusion x-tra compared with Grandio significantly (p < 0.05).
Although both materials showed acceptable clinical performance over 2 years, a significant difference was observed between the surface luster, surface staining, marginal adaptation, and staining of the nano-hybrid composite placed with the incremental technique and the bulk-fill ORMOCER-based composite resin.
As an alternative to nano-hybrid composite resins, using bulk-fill restorative materials, which can be indicated in the proper case, may contribute to shortening treatment procedures and increasing patient and physician comfort, leading to clinical success.
本研究旨在采用双侧对照设计，比较大体积充填复合树脂与纳米混合充填复合树脂在6至12岁儿童中的2年临床性能。
本随机、双侧对照、双盲研究针对89例6至12岁双侧下颌第一磨牙患龋的患者开展。采用双侧对照设计，下颌恒磨牙的修复分别使用基于纳米混合有机改性陶瓷（ORMOCER）的大体积充填复合树脂Admira Fusion x-tra（德国库克斯港Voco GmbH公司）和纳米混合复合树脂Grandio（德国库克斯港Voco公司）。使用Futurabond U单剂量产品（德国库克斯港Voco公司）进行选择性釉质酸蚀。在6个月、12个月和24个月的随访检查中，依据美国公共卫生署（USPHS）和国际牙科联盟（FDI）标准评估修复体的临床成功率。
在2年的随访中，所有修复体在临床上均可接受。就表面光泽和表面变化而言，Grandio显著差于Admira Fusion x-tra（p < 0.05）。与Grandio相比，Admira Fusion x-tra的表面染色和颜色匹配评分显著增加（p < 0.05）。
尽管两种材料在2年期间均表现出可接受的临床性能，但采用分层技术放置的纳米混合复合树脂与基于ORMOCER的大体积充填复合树脂在表面光泽、表面染色、边缘适应性和染色方面存在显著差异。
作为纳米混合复合树脂的替代材料，在适当情况下使用大体积充填修复材料可能有助于缩短治疗程序，提高患者和医生的舒适度，从而取得临床成功。
