Developmental defects of enamel are visible deviations from the normal translucent appearance of tooth enamel resulting from enamel organ dysfunction. In the past, information about the activities of the ameloblasts has determined the terminology used to describe the lesions. Advances in our understanding of the complicated secretory and maturation phases of amelogenesis have required a re-appraisal of the concepts of defect formation. The phase of ameloblast activity, the duration of the disturbance, and its severity leading to temporary or permanent inactivity of the cells determine the appearance of the three common types of lesions--hypoplasia, and diffuse and demarcated opacities.
牙釉质发育缺陷是由于成釉器功能障碍导致牙釉质正常半透明外观出现明显偏差。过去，关于成釉细胞活动的信息决定了用于描述病变的术语。随着我们对釉质形成复杂的分泌和成熟阶段的理解不断深入，需要重新评估缺陷形成的概念。成釉细胞活动阶段、干扰持续时间及其严重程度导致细胞暂时或永久失活，这些因素决定了三种常见病变类型——发育不全、弥漫性和界限性混浊——的外观。
