To evaluate the effect of different modeling agents on color changes, surface roughness, and translucency parameters over time in Bulkfill resin composites.
Sixty specimens were prepared using three Bulkfill resin composites (Tetric N-Ceram Bulkfill, Filtek One Bulkfill and Opus Bulkfill) and three modeling agents (Wetting Resin, Optibond FL and Ambar APS). All specimens were subjected to a simulated tooth-brushing (Baseline, 50.000 cycles, 100.000 cycles), and surface roughness was measured at each interval. Surface topography was evaluated. The translucency parameter and color changes were assessed after 24-h, 7-, 14- and 30-day immersion in water, wine, and coffee. Data was analyzed using ANOVA and Bonferroni test.
All specimens increased roughness after simulated tooth-brushing (p < 0.05). Wetting Resin decreased roughness on Tetric N-Ceram Bulkfill (p < 0.05). The translucency parameter remained unaltered for all groups. All groups changed color after 30-days of immersion in wine and coffee (p < 0.05). Ambar APS and Wetting Resin on Tetric N-Ceram Bulkfill showed higher color changes when immersed in coffee (p < 0.05).
The use of modeling agents does not jeopardize translucency properties but may affect surface roughness and color properties of Bulkfill resin composites depending on their composition.
The findings of this study suggest that surface roughness and color properties are affected by the differences in the composition between modeling agents and Bulkfill resins composites.
评估不同的成型剂对大块充填树脂复合材料随时间变化的颜色、表面粗糙度和半透明参数的影响。
使用三种大块充填树脂复合材料（Tetric N-Ceram Bulkfill、Filtek One Bulkfill和Opus Bulkfill）和三种成型剂（湿润树脂、Optibond FL和Ambar APS）制备60个样本。所有样本均接受模拟刷牙（基线、50000次循环、100000次循环），并在每个时间间隔测量表面粗糙度。评估表面形貌。在将样本分别浸泡于水、葡萄酒和咖啡中24小时、7天、14天和30天后，评估半透明参数和颜色变化。使用方差分析和Bonferroni检验对数据进行分析。
所有样本在模拟刷牙后粗糙度均增加（p < 0.05）。湿润树脂降低了Tetric N-Ceram Bulkfill的粗糙度（p < 0.05）。所有组的半透明参数均未改变。所有组在浸泡于葡萄酒和咖啡3天后颜色均发生变化（p < 0.05）。当浸泡于咖啡中时，Tetric N-Ceram Bulkfill上的Ambar APS和湿润树脂显示出更大的颜色变化（p < 0.05）。
成型剂的使用不会损害半透明性能，但可能会根据其成分影响大块充填树脂复合材料的表面粗糙度和颜色性能。
本研究结果表明，表面粗糙度和颜色性能受成型剂与大块充填树脂复合材料之间成分差异的影响。
