氟斑牙(斑釉)是牙齿氟中毒的表现,它的临床特征是釉质上常常平行地出现白色条纹,釉质横纹常增强,后牙的白色条纹常沿着牙尖嵴伸展下来。氟斑牙经常两侧对称,并且发生在牙列上的几个牙齿,甚至全部牙齿。最常见的是第二磨牙,其次是上切牙、尖牙、第一磨牙、最后为下切牙。重症氟斑牙牙齿成棕黄色并有缺损,或伴发釉质发育不全。氟斑牙的病因已经明确是由于牙发育时期机体摄入的氟量过高。 Fluorosis (spot glaze) is a manifestation of dental fluorosis. Its clinical feature is that white streaks often appear parallel to the enamel, enamel horizontal stripes often increase, and white streaks of the posterior teeth often extend along the cusp ridge. Frequently dental fluorosis is bilaterally symmetrical and occurs on several or even all of the teeth in the dentition. The most common is the second molars, followed by the upper incisors, canines, first molars, and finally the lower incisors. Severe dental fluorosis teeth into brown and have defects, or with enamel hypoplasia. The cause of dental fluorosis has been clearly due to excessive intake of fluoride during the period of tooth development.
