AIM
To evaluate and compare the microhardness of Filtek Z250XT, Beautifil II, and Neo Spectra ST HV after immersion in chlorhexidine mouthwash.
MATERIALS AND METHODS
Thirty disc specimens (10 for each group) made of three different restorative materials, Group 1 - Filtek (3M ESPE), Group 2 - Beautifil II (Shofu), and Group 3 - Neo Spectra ST HV (Dentsply). To simulate 1 year of daily mouthwash use, 10 specimens from each group were immersed in chlorhexidine, kept in an incubator at 37°C for 12 h, and later subjected to microhardness measurement using Vicker's hardness test. Finally, analysis of variance and post hoc tests were used to analyze the results statistically.
RESULTS
A significant reduction in microhardness was observed after immersion in chlorhexidine in Groups 1 and 3 compared to Group 2.
CONCLUSIONS
Filtek Z250XT exhibits the highest microhardness compared to the other two materials. However, Beautifil II is more resistant to chlorhexidine mouthwash and does not show a significant reduction compared to the other two restorative materials.
目的
评估并比较Filtek Z250XT、Beautifil II和Neo Spectra ST HV浸泡在洗必泰漱口液后的显微硬度。
材料与方法
由三种不同修复材料制成30个圆盘标本（每组10个），第1组 - Filtek（3M ESPE），第2组 - Beautifil II（松风），第3组 - Neo Spectra ST HV（登士柏）。为模拟每日使用漱口水1年的情况，每组10个标本浸泡在洗必泰中，置于37°C培养箱中12小时，随后使用维氏硬度测试进行显微硬度测量。最后，采用方差分析和事后检验对结果进行统计学分析。
结果
与第2组相比，第1组和第3组浸泡在洗必泰后显微硬度显著降低。
结论
与其他两种材料相比，Filtek Z250XT表现出最高的显微硬度。然而，Beautifil II对洗必泰漱口水更具抗性，与其他两种修复材料相比未显示出显著降低。
