To assess the penetration and microleakage of a resin infiltrant for the prevention of noncavitated white lesion progression in the fissure system of permanent teeth and compare it to a conventional sealant.
Sixty extracted permanent teeth with artificially produced noncavitated white lesions were randomly distributed according to the restorative material into group I (experimental) which received ICON resin infiltration, and group II (control) which received Helioseal F fissure sealant. For the penetration test, restorative materials were mixed with a fluorescent dye (eosin H) before light curing; roots were then amputated, and three buccopalatal microscopic sections were obtained from each tooth. These were dipped in 0.001 mg of ethanolic sodium fluorescence solution. Material penetration depth was assessed through confocal microscopy. Thirty teeth (15 from each group) underwent a microleakage test. Teeth were thermocycled, and then immersed in 50% silver nitrate (AgNO) solution for 3 hours. Microleakage was evaluated using X-ray microtomography (micro-CT); AgNO presence between the material and the tooth surface indicated microleakage.
The mean material penetration value in teeth treated with ICON (104.8571 ± 7.63360 μm) was significantly higher than that in teeth treated with Helioseal F (5.3158 ± 3.83825 μm) ( < 0.001). The mean microleakage value in demineralized enamel treated with Helioseal F (0.2238 ± 0.12561) was significantly greater than that in demineralized enamel treated with ICON (0.0119 ± 0.0097) ( < 0.001).
ICON displayed more penetration and less microleakage than Helioseal F in pits and fissures of permanent teeth.
Resin infiltrant showed superior retention and can provide a good alternative for adhesives and fissure sealants.

评估一种树脂浸润剂在预防恒牙窝沟系统中非龋性白色病变进展方面的渗透情况和微渗漏情况，并将其与传统窝沟封闭剂进行比较。
60颗带有人工制造的非龋性白色病变的离体恒牙，根据修复材料随机分为两组，第一组（实验组）采用ICON树脂浸润，第二组（对照组）采用Helioseal F窝沟封闭剂。在光固化前，将修复材料与荧光染料（伊红H）混合用于渗透测试；然后截除牙根，从每颗牙齿获取三个颊舌向的显微切片。将这些切片浸入0.001毫克的乙醇钠荧光溶液中中通过共聚焦显微镜评估材料的渗透深度。30颗牙齿（每组15颗）进行微渗漏测试。对牙齿进行热循环处理，然后浸入50%的硝酸银（AgNO）溶液中3小时。使用X射线显微断层扫描（显微CT）评估微渗漏情况；材料与牙齿表面之间存在硝酸银表明存在微渗漏。
用ICON处理的牙齿中材料的平均渗透值（104.8571±7.63360μm）显著高于用Helioseal F处理的牙齿（5.3158±3.83825μm）（P<0.001）。用Helioseal F处理的脱矿釉质中的平均微渗漏值（0.2238±0.12561）显著高于用ICON处理的脱矿釉质（0.0119±0.0097）（P<0.001）。
在恒牙的窝沟中，ICON比Helioseal F表现出更多的渗透和更少的微渗漏。
树脂浸润剂显示出更好的封闭效果，可为粘结剂和窝沟封闭剂提供良好的替代选择。如何引用本文：Al-Tuwirqi AA, Alshammari AM, Felemban OM, 恒牙窝沟中树脂浸润剂与传统窝沟封闭剂的渗透深度和微渗漏比较。《当代牙科实践杂志》2019；20(11):1339 - 1344。
