每一位父母都希望自己的孩子有一口洁白整齐健康的牙齿,然而我们从幼儿园体检中发现,儿童不仅龋齿的发病率高,而且有些儿童牙齿表面不光滑,或染有棕黄色斑块,甚至与牙面呈不规则的小窝相连。有的儿童虽然牙齿结构表面完整,但基质疏松而不坚硬。出现这些情况,一般讲与婴儿的营养障碍有关。 孕期和哺育期的营养很重要,因为乳牙在胚胎2个月就开始发育,5—6个月钙化,第一组磨牙在胚胎4个月开始发育,所以母亲的饮食营养如何,不仅影响胎儿和婴幼儿的身体发育,而且与乳牙的发育直接相关。在牙齿的发育形成过程中,蛋白质、钙、磷、氟和维生素A、C、D都是必要的营养成分,足月的胎儿体内含钙30克、磷18克,均是在母亲孕期尤其是最后三个月中从母体获取的。有资料表明,我国孕妇早、中、晚期的热能 Every parent wants their children to have a neat and tidy healthy tooth.

The full-term fetus contains 30 grams of calcium and 18 grams of phosphorus, all during pregnancy Obtain from mother in the last three months. Data show that China's pregnant women early, middle and late heat
