This case report describes a technique used to treat smooth surface white spot lesions microinvasively. It is based on the infiltration of an initial enamel caries lesion with low-viscosity light-curing resins called infiltrants. The surface layer is eroded and desiccated, followed by resin infiltrant application. The resin penetrates into the lesion microporosities driven by capillary force and is hardened by light curing. Infiltrated lesions lose their whitish appearance and look similar to sound enamel. Additionally, the treatment prevents lesion progression. This technique might be an alternative to microabrasion and restorative treatment in treating of white spot lesions of esthetically relevant teeth.
本病例报告描述了一种用于微创治疗平滑面白斑病变的技术。它基于用一种名为渗透剂的低粘度光固化树脂浸润早期釉质龋损。首先对表层进行酸蚀和干燥处理,然后应用树脂渗透剂。树脂在毛细作用力的驱动下渗入病变微孔,并通过光固化变硬。经渗透处理的病变失去白色外观,看起来与正常釉质相似。此外,该治疗可防止病变进展。在治疗美观相关牙齿的白斑病变方面,这项技术可能是微磨除术和修复治疗的一种替代方法。
