2,516 children of both sexes, six to fourteen years old, were examined in Jordan in the course of an epidemiological study. 81.11% of girls and 76.43% of boys presented severe forms of dental fluorosis according to DEAN's index. Drinking water analysis revealed fluoride concentrations ranging from 0.27 to 1.4 mg F/l. These concentrations are neighbouring optimum tolerated fluoride supplementation in drinking water. However high annual temperature mean and ten hours daily sunshine must also be taken in consideration. For social and climatic reasons, Jordanian children drink daily high quantities of tea. Analysis of tea prepared on jordanian way revealed a concentration of 1.2 mg F/l. This continuous intake of fluoride might explain the high severity of dental fluorosis in Jordan.
在一项流行病学研究过程中，对约旦2516名6至14岁的儿童进行了检查。根据迪恩指数，81.11%的女孩和76.43%的男孩患有严重的氟斑牙。饮用水分析显示氟化物浓度在0.27至1.4毫克氟/升之间。这些浓度接近饮用水中可耐受的最佳氟化物补充量。然而，年平均气温高和每日日照十小时也必须考虑在内。由于社会和气候原因，约旦儿童每天饮用大量的茶。对按照约旦方式冲泡的茶进行分析发现，氟化物浓度为1.2毫克氟/升。这种持续的氟摄入可能解释了约旦氟斑牙的高严重程度。
