In recent years, there have been suggestions for new restorative strategies that aim to effectively utilize modern adhesive technologies and protect the remaining intact tooth structure. This study was conducted to evaluate the clinical performance of fiber reinforced resin composites in restoring Class II MOD cavities over 18 months.
Forty-five participants with class II MOD cavities were randomly enrolled. The participants were allocated to three groups (n = 15): Group (1) short glass fiber reinforced resin composite (EverX Posterior), Group (2) polyethylene fiber (Ribbond-Ultra) reinforced resin composite and Group (3) only conventional resin composite (Filtek Z250). The modified USPHS criteria were used to evaluate the restorations at baseline; and at three, six, 12 and 18 months. The categorical data were reported as frequencies and percentages. Intergroup comparisons were analyzed using Chi-Square test after Bonferroni correction (P ≤ 0.016). Comparisons within each group were analyzed using Cochran's Q test after Bonferroni correction (P ≤ 0.005).
Intergroup comparisons revealed no statistically significant differences in any of the evaluated criteria except for color match. Compared with the other groups, the short glass fiber-reinforced restoration group presented significantly fewer color matches at different follow-up periods.
Class II direct fiber-reinforced resin composite restorations can offer acceptable performance similar to the nanohybrid resin composite through 18-month of clinical service.
Fiber reinforcement of resin composites could be a reliable technique for restoring posterior cavities considering factors such as application complexity, cost and aesthetic considerations.
The trial was registered retrospectively on (19/05/2022) at https://clinicaltrials.gov with the ID (NCT05380973).
近年来，有人提出了新的修复策略，旨在有效利用现代粘接技术并保护剩余的完整牙体结构。本研究旨在评估纤维增强树脂复合材料修复Ⅱ类MOD洞18个月后的临床性能。
随机招募45名患有Ⅱ类MOD洞的参与者。参与者被分为三组（n = 15）：第1组为短玻璃纤维增强树脂复合材料（EverX Posterior），第2组为聚乙烯纤维（Ribbond-Ultra）增强树脂复合材料，第3组仅为传统树脂复合材料（Filtek Z250）。采用改良的美国公共卫生服务标准在基线时以及3、6、12和18个月时评估修复体。分类数据以频率和百分比报告。组间比较在Bonferroni校正后使用卡方检验进行分析（P≤0.016）。每组内的比较在Bonferroni校正后使用 Cochr an Q检验进行分析（P≤0.005）。
组间比较显示，除颜色匹配外，在任何评估标准中均无统计学显著差异。与其他组相比，短玻璃纤维增强修复组在不同随访期的颜色匹配明显较少。
Ⅱ类直接纤维增强树脂复合材料修复体在18个月的临床服务中可提供与纳米混合树脂复合材料相似的可接受性能。
考虑到应用复杂性、成本和美学等因素，树脂复合材料的纤维增强可能是修复后牙洞的可靠技术。
该试验于（2022年5月19日）在https://clinicaltrials.gov上进行回顾性注册，注册号为（NCT05380973）。
