Enamel hypoplasia is a defect left by teeth in the process of jaw development and mineralization, but it was discovered after eruption, which is not a reflection of the health status of teeth after eruption. Therefore, it is meaningless to supplement vitamin D and minerals for this circulating subgroup.

Control: 1. Paying attention to maternal and child health care can prevent the occurrence of this disease;

2. Because of the poor mineralization of the affected teeth, it is easy to wear. After suffering from caries, it develops rapidly, so caries prevention treatment should be carried out;

3. Teeth with mild symptoms do not need treatment; Severe teeth can be covered with composite resin or restoration, which can not only improve the appearance, but also help to prevent caries.
