不同日摄氟量居民罹患氟斑釉的研究

RESEARCH ON THE FLUORIDE MOTTLED ENAMEL OF THE RESIDENTS WITH DIFFERENT DAILY FLUORIDE INTAKE

人和动物体内的硬组织（牙齿、骨骼等）是氟化物作用的主要部位，严重者可引起氟骨症和氟斑釉，其中氟斑釉是慢性氟中毒的一项特异指标。通常日摄氟量高的居民其氟斑釉率和斑釉指标均增高。本文用日摄氟量作指标评价环境氟对居民牙齿的影响。研究结果揭示，当地居民的斑釉率和斑釉指数均与日摄氟量呈非常显著的正相关，ｒ＝０．９０８４，Ｐ＜０．０１。

The influence of environmental fluoride on the teeth of the residents was assessed with daily fluoride intake as the index.The results show that both the rate and the index of mottled enamel in the residents in the investigated areas are positively correlated to the daily fluoride intake quite significantly.
