The study is aimed to assess the effect of 3 Saudi-traditional types of mouth rinses (Karadah, Myrrh, salted water) on the microleakage of composite and glass-ionomer restorations subjected to thermal cycling and cyclic loading.
Class V cavities in both buccal and lingual surfaces of eighty extracted premolars were restored with both nano-filled composite and glass-ionomer restoratives. Half the number of restored teeth (group 1, n = 40) were subjected to further thermal cycling and cyclic loading to mimic the in-service functional stresses. The rest of the teeth were left as control with no functional simulation (group 2, n = 40). Teeth of each group were then stored wet for one month in 4 subgroups (n = 10) according to the storage media (distilled water, salted water, Myrrh and Karadah extracts). Following wet ageing, all teeth were immersed in methylene blue solution for 24 hrs, followed by sectioning in Bucco-lingual direction. The microleakage was inspected using stereomicroscope and rated from 0-4 according to its penetration depth. The collected non-parametrical data was then analysed statistically using Kruskal-Wallis One-way ANOVA at α = 0.05.
There was no statistically significant difference observed in microleakage between specimens treated with any of the mouthwashes for both glass ionomer and composite restorations in the presence and absence of thermal cycling and cyclic loading (p = 0.889).
Given the results of the present study, the Saudi-traditional types of mouth rinses are not contributory to microleakage in aesthetic-based composite and glass-ionomer restorations.
本研究旨在评估3种沙特传统漱口水（卡拉达、没药、盐水）对经受热循环和循环加载的复合树脂及玻璃离子修复体微渗漏的影响。
选取80颗拔除的前磨牙，在其颊面和舌面制备Ⅴ类洞型，分别用纳米复合树脂和玻璃离子修复材料进行修复。半数修复后的牙齿（第1组，n = 40）进一步经受热循环和循环加载，以模拟实际使用中的功能应力。其余牙齿作为对照组，不进行功能模拟（第2组，n = 40）。然后，根据储存介质（蒸馏水、盐水、没药提取物和卡拉达提取物），将每组牙齿湿存1个月，分为4个亚组（n = 10）。湿老化后，将所有牙齿浸入亚甲蓝溶液中24小时，然后沿颊舌方向切片。使用体视显微镜检查微渗漏情况，并根据其渗透深度从0至4进行评级。收集的非参数数据随后使用Kruskal-Wallis单因素方差分析进行统计学分析，α = 0.05。
对于玻璃离子和复合树脂修复体，无论有无热循环和循环加载，使用任何一种漱口水处理的标本之间在微渗漏方面均未观察到统计学显著差异（p = 0.889）。
根据本研究结果，沙特传统类型的漱口水对基于美学的复合树脂和玻璃离子修复体的微渗漏没有影响。
