Abstract：
OBJECTIVE: The aim of the study was to compare and evaluate the microleakage of fiber-reinforced glass ionomer cement (GIC) and conventional glass ionomer cement restorations immersed in three different beverages.
METHODS: A total of 96 human exfoliating deciduous molars were selected which were cleaned and disinfected. Standardized Class V cavity preparations were done and buccal surface were restored with experimental fiber-reinforced glass ionomer cement (Exp-FRGIC), lingual surface were restored with Type II conventional GIC. They were divided into four groups according to the test beverage. The samples were subjected to various immersion regimes and evaluated for microleakage under stereomicroscope.
RESULTS: Intragroup comparison for (Exp-FRGIC) showed significant microleakage when immersed in fresh fruit juice at high immersion whereas intragroup comparison in conventional GIC, showed highest microleakage with soft drink. Intergroup comparison of (Exp-FRGIC) in high immersion regime, showed more microleakage with specimen immersed in soft drink followed by fresh fruit juice.
CONCLUSIONS: It can thus be concluded that the three beverages used in the study affected the microleakage of both restorative materials significantly.
CONCLUSIONS: Increasing usage of fruit juices in the pediatric diet has a definite impact on the progression of caries and it directly or indirectly affects the quality of restorations placed in the oral cavity.

摘要：
目的：研究的目的是比较和评估浸入三种不同饮料中的纤维增强玻璃离聚物水泥（GIC）和常规玻璃离聚物水泥修复体的微渗漏。
方法：共选择96颗人类脱落型落叶磨牙，并进行清洗和消毒。完成了标准化的V类腔准备，并使用实验性纤维增强的玻璃离聚物水泥（Exp-FRGIC）恢复了颊表面，用II型常规GIC恢复舌面。根据测试饮料将他们分为四组。对样品进行各种浸没方案，并在立体显微镜下评估微渗漏。
结果：（Exp-FRGIC）的组内比较显示，在高浸泡状态下浸入新鲜果汁中时，显着微渗漏，而在常规GIC中，组内比较显示，软饮料的微渗漏最高。在高浸泡状态下（Exp-FRGIC）的组间比较，样品浸入软饮料中，然后是新鲜果汁，显示出更多的微渗漏。
结论：因此可以得出结论，研究中使用的三种饮料对两种修复材料的微渗漏都有显着影响。
结论：在儿科饮食中增加果汁的使用对龋齿的进展有一定的影响，它直接或间接地影响口腔内修复物的质量。如何引用这篇文章：乔治·马，ChandakSA,KhekadeSH,etal.纤维增强玻璃离聚物水泥和常规玻璃离聚物水泥修复在三种不同饮料中的微渗漏的比较评价：体外研究。JContempDentPract2024；25（4）：346-353。
