随着牙面酸蚀刻技术的应用和发展,自六十年代起,高分子合成材料已逐渐成为预防少年儿童点隙龋的一种有效新材料和新途径。把它涂在经酸蚀刻处理后的牙(牙合)面,利用它粘稠度低,渗透性好,快速固化成膜而将易发龋蚀的点隙裂沟封闭起来,起一屏障作用,隔绝外来有害刺激以预防点隙龋。 With the application and development of tooth surface acid etching technology, polymer composites have gradually become an effective new material and new way to prevent point caries in children since the 1960s. Apply it to the surface of the tooth (occlusal) treated with acid etching, and use it to have low viscosity, good permeability and rapid solidification to form a film that will seal the gap-prone fissures of the caries and act as a barrier , Isolated from harmful foreign stimuli to prevent point caries.
