Upper incisor teeth from sheep infected with parasites or given 6 mg fluoride per kg bodyweight for 21 days during the period of tooth formation were examined with SEM and microradiography. It was found using both techniques that there had been a severe disturbance of the secretory ameloblasts leading to enamel hypoplasia. It is suggested that it is the severity rather than the cause of the insult to the ameloblasts which determines the degree of hypoplasia.
对在牙齿形成期感染寄生虫或每千克体重给予6毫克氟持续21天的绵羊的上门牙，用扫描电子显微镜（SEM）和显微放射照相术进行了检查。使用这两种技术均发现，分泌性成釉细胞受到严重干扰，导致釉质发育不全。有人提出，决定发育不全程度的是对成釉细胞损伤的严重程度而非损伤原因。
