牙釉质对脱矿作用的抵抗力是影响龋齿发生和发展的重要因素之一。有一些调查表明,停止龋区域的抗脱矿能力比无龋区域强。发生变化的牙釉质矿物质密度减低,有机物含量增高,氟含量增高,这表明早期釉质龋病变与菌斑液和唾液之间相互作用,发生修复反应。作者将发生了龋蚀和再矿化作用的釉质龋称为强化病变(lesion consolid- Enamel resistance to demineralization is one of the important factors that affect the occurrence and development of dental caries. Some surveys have shown that resistance to demineralization in carious areas is stronger than in caries-free areas. Decreased enamel mineral density, increased organic content, and increased fluoride levels indicate that early enamel lesions interact with plaque and saliva and undergo a repair response. The authors have enamel caries and remineralization of the caries called lesions (lesion consolid-
