The aim of this study is to evaluate the surface microhardness and roughness of composites treated with three different polishing systems exposed to two different corrosive beverages.
Ninety-six composite resin disks were randomly divided into four groups, one of which was the control group. The surface roughness and microhardness values were measured after 24 h in the polishing process. The samples were divided into three subgroups and kept in distilled water, cola, and ice tea for 20 min a day for 14 days. Then, the roughness and microhardness measurements of the samples were taken again. Two samples randomly selected from each group were examined using a scanning electron microscope (SEM) and analyzed statistically using the two way anova (ANOVA) and Duncan tests.
A statistically significant difference was found between the roughness and hardness values at the end of 24 h and 14 days. Onegloss (OG), Dentoflex (DF), and Super-snap (SNP) polish systems showed the highest roughness in the cola group, respectively. Microhardness values: The unpolished group had the lowest significant microhardness in the coke group (P < 0.05).
In this study, it was seen that the lowest success rate was the OG polishing system.
本研究旨在评估三种不同抛光系统处理后的复合材料的表面显微硬度和粗糙度,同时暴露于两种不同腐蚀性饮料中。
将 96 个复合树脂圆盘随机分为四组,其中一组为对照组。在抛光过程 24 小时后测量表面粗糙度和显微硬度值。将样本分为三组,每天在蒸馏水、可乐和冰茶中浸泡 20 分钟,持续 14 天。然后,再次对样本的粗糙度和显微硬度进行测量。从每组中随机选择两个样本,使用扫描电子显微镜(SEM)进行检查,并使用双因素方差分析(ANOVA)和 Duncan 检验进行统计分析。
在 24 小时和 14 天后,粗糙度和硬度值之间存在统计学显著差异。Onegloss(OG)、Dentoflex(DF)和 Super-snap(SNP)抛光系统在可乐组中表现出最高的粗糙度。显微硬度值:未抛光组在可乐组中表现出最低的显著显微硬度(P < 0.05)。
在这项研究中,观察到最低成功率的是 OG 抛光系统。
