This study evaluated the influence of the penetration coefficient (PC) and ethanol addition on the penetration depth (PD) of experimental infiltrants into proximal caries lesions in primary molars. Caries lesions (n = 45) were randomly treated with 1 of 4 experimental infiltrants (PC63; PC185; PC204; PC391) for 5 min. Lesion depths and PDs were analysed using dual fluorescence confocal microscopy. Lesions were almost completely infiltrated in all groups. Median PDs and percentage penetrations were not significantly different between groups (p > 0.05). When applied for 5 min, all tested infiltrants were able to infiltrate proximal caries in primary molars nearly completely.
本研究评估了渗透系数 (PC) 和乙醇添加对实验性渗透剂进入乳磨牙近中龋损深度的影响。随机将 45 个龋损用 1 种（PC63；PC185；PC204；PC391）的 4 种实验性渗透剂中的 1 种处理 5 分钟。使用双荧光共聚焦显微镜分析病变深度和渗透深度。所有组的病变几乎都被完全渗透。组间 PD 和渗透率中位数无显著性差异（p > 0.05）。当应用 5 分钟时，所有测试的渗透剂都能几乎完全渗透乳磨牙的近中龋。
