The purpose of this study was to evaluate the performance of polyethylene fiber reinforced resin composite fillings compared to bulk fill resin composite fillings in endodontically treated teeth over a two-year monitoring period.
A total of 240 individuals with endodontically treated lower molars and a moderate amount of tooth structure were divided into two equal groups of 120 each. One group received polyethylene fiber reinforced bulk fill resin composite restorations while the other group received only bulk fill resin composite restorations, both applied as per manufacturer guidelines. Two proficient experienced blinded assessors assessed the restorations using modified USPHS criteria at baseline, 6, 12, and 24 months.
Data analysis involved the utilization of Mann-Whitney U, Friedman's test, and Nemenyi post hoc test, with age data being displayed as mean and standard deviation. The significance level was established as p < 0.05, and R software was utilized for statistical analysis.
There were no notable distinctions in any parameters or scores between the intervention and comparator groups at various time points. Alpha scores were present for retention, gross fracture, and secondary caries at all follow up intervals.
Both direct resin composite restorations reinforced with polyethylene fibers and direct bulk fill resin composite restorations placed in endodontically treated molars with moderate remaining tooth structure demonstrated satisfactory clinical outcomes during a 24-month follow-up period.
Bulk fill resin composites directly placed in endodontically treated molars with moderate remaining tooth structure showed promise as a treatment option over a two-year period.

本研究旨在评估在两年监测期内，聚乙烯纤维增强树脂复合材料充填与大体积充填树脂复合材料充填在根管治疗后的牙齿中的性能。
共 240 名接受根管治疗的下颌磨牙且牙体组织有中度缺损的个体，随机分为两组，每组 120 人。一组使用聚乙烯纤维增强型大体积充填树脂复合材料修复，另一组仅使用大体积充填树脂复合材料修复，两组均按制造商指南使用。两名熟练的经验丰富的盲法评估员使用改良的 USPHS 标准在基线、6、12 和 24 个月时评估修复体。
数据分析包括使用 Mann-Whitney U、Friedman 检验和 Nemenyi 事后检验，年龄数据以平均值和标准差表示。显著水平设定为 p < 0.05，使用 R 软件进行统计分析。
在不同时间点，干预组和对照组在任何参数或评分上均无显著差异。在所有随访间隔中，保留、总裂和继发龋均存在 Alpha 评分。
在中度剩余牙体结构的根管治疗磨牙中，使用聚乙烯纤维增强的直接树脂复合材料修复体和直接大体积充填树脂复合材料修复体，在 24 个月的随访期间均显示出满意的临床效果。
直接在中度剩余牙体结构的根管治疗磨牙中使用大体积充填树脂复合材料，在两年内有望成为一种治疗选择。
