The expression was down-regulated with enamel and dentin matrix formation being up-regulated. 随后其表达随细胞分化的成熟和牙釉质、牙本质基质形成的进展而逐渐下降。
Enamel, the formation of protective film, to make your teeth more strong, healthy. 珐琅质,形成保护膜,使您的牙齿更坚固,健康。
Touching up damage to accessible enamel and primer in a timely manner can prevent the formation of corrosion pits and reduce the need for excessive rework during overhaul. 用时效方法可接近的珐琅和底漆进行接触性损伤检查有助于预防腐蚀斑点的形成并减少大修工作量。
Objective: To study the effects of several remineralization solutions with different composition on the artificial demineralization lesions of bovine enamel and the mechanism of remineralization layer formation. 目的:观察不同成份的再矿化液对人工釉质龋表层下脱矿的再矿化作用及再矿化层的形成机理。
[ Objective] To investigate the carious dissolution mechanism of individual enamel crystals and formation mechanism of the body of the lesion in incipient enamel caries. [目的]探讨早期釉质龋中釉质微晶的溶解方式及病变体部的形成机制。
METHODS: Fresh cow enamel was used, to measure the hardness, with HX-1000 type hardness measurer, before and after fluoride application and artificial caries formation separately. 方法:采用新鲜牛牙釉质块为标本,应用显微硬度计测量分别采用氟化钠泡沫、氟化钠凝胶进行矿化试验和抗龋试验后的釉质块表面显微硬度。
