Abstract

Background: The aim was to examine the effect of three polishing systems (TwistDia, SuperSnap, and Opti 1Step) and additional polishing on the surface roughness and color change of two universal resin composites (OptiShade and Omnichroma) immersed in coffee.

Methods: A total of 80 samples were prepared, 40 samples for each of the resin composites (n:10). For the control group no polishing step was applied. Other samples were polished using Twist Dia, Opti 1Step, or SuperSnap. The baseline (T0) surface roughness and color parameters of the samples were measured. After the samples were immersed in coffee for 12 days (T1), and after the surface of the samples was polished, each sample were measured (T2).

Results: In both universal resin composites, the lowest surface roughness values were obtained from the control group (p < 0.05). The highest surface roughness values were observed in the group polished with SuperSnap of OptiShade resin, both after immersed in coffee and after additional polishing(p < 0.05). İt was observed that samples prepared with OptiShade resin composite samples generally showed lower ΔE values compared than the other resin composites.

Conclusions: Additional polishing applications, caused changes in color parameters and increases in surface roughness in single shade resin composites, although not statistically significant.

附加抛光对单色树脂复合材料颜色稳定性和表面粗糙度的影响。

背景：目的是研究三种抛光系统（TwistDia、supernap和Opti 1Step）和额外抛光对两种通用树脂复合材料（OptiShade和Omnichroma）浸在咖啡中的表面粗糙度和颜色变化的影响。方法：共制备80个样品，每种树脂复合材料各40个样品（n:10）。对于对照组，不使用抛光步骤。其他样品使用Twist Dia， Opti 1Step或SuperSnap抛光。测量样品的基线（T0）表面粗糙度和颜色参数。样品在咖啡中浸泡12天后（T1），并在样品表面抛光后测量每个样品（T2）。结果：在两种通用树脂复合材料中，从对照组获得的表面粗糙度值最低(p)。结论：在单色树脂复合材料中，额外的抛光应用会导致颜色参数的变化和表面粗糙度的增加，尽管没有统计学意义。
