Although dental caries destroys dental hard tissues, both demineralization as a destructive process and remineralization as a restorative process take place in carious lesions. These conflicting processes occur constantly either simultaneously or alternately. In crystallographic terms, demineralization is crystal dissolution, and remineralization is restoration of partially dissolved crystals, new crystal formation and growth of surviving crystals. In this review, we employ high-resolution transmission electron microscopy to demonstrate demineralization and remineralization of enamel crystals obtained from cross-cut sections of the c-axes of crystals from carious lesions.
尽管龋齿会破坏牙齿硬组织，但脱矿作为一种破坏过程和再矿化作为一种修复过程都在龋损中发生。这些相互矛盾的过程持续不断地同时或交替出现。从晶体学角度来看，脱矿是晶体溶解，而再矿化是部分溶解晶体的修复、新晶体形成以及存活晶体的生长。在本综述中，我们采用高分辨率透射电子显微镜来展示从龋损晶体c轴的横切面上获取的釉质晶体的脱矿和再矿化情况。
