为了解西藏境内夏尔巴儿童氟斑牙、龋病的发病情况及其与膳食结构的关系，使用Ｈｏｒｏｗｉｔｚ 氟斑牙检查方法，ＷＨＯ推荐的龋齿检查方法，Ｗ ＨＯ 和ＦＡＯ 编写的总摄氟量调查方法，对珠穆朗玛峰下樟木镇的夏尔巴儿童和藏族儿童进行了对比性调查。结果显示，在己知的中国砖茶型氟中毒流行地区中，该地的发病率最低（ 夏尔巴儿童氟斑牙发病率为３７－４０ ％ ，属轻度流行，藏族儿童为２５－８６ ％ ，接近许可范围） 。夏尔巴儿童的龋患率和龋均（ ２８ ．４６ ％ ，０－６２ ） 低于本地藏族儿童（６２－０７ ％ ，２－１７） 。膳食结构调查结果表明，樟木镇儿童膳食结构的改变使氟摄入减少，增加了多种营养成分摄入，增强了机体抵御氟损害的能力。夏尔巴儿童龋患率低的原因可能来自于较为合理的膳食结构。藏族儿童的高龋患率来自于精细食品及蔗糖消费的大幅度上升。夏尔巴儿童如能适当减少含砖茶的酥油茶和糌耙的摄入，有可能为砖茶型氟中毒流行地区提供一种减少氟损害和龋病流行的模式
In order to understand the incidence of dental fluorosis and dental caries in Sherpa children in Tibet and their relationship with dietary structure, Horowitz fluorosis test, the recommended caries inspection method recommended by the WHO, W HO and the total amount of fluoride prepared by FAO Survey methodology was used to conduct a comparative survey of Sherpa and Tibetan children in Camphor Town, Everest. The results showed that the prevalence of brick-fracking fluorosis in China was the lowest (the prevalence of dental fluorosis was 37-40% in Sherpas, which was mild to severe, 25-86% in Tibetan children, , Close to the allowable range). The caries prevalence and caries of Sherpa children (28.46%, 0-62) were lower than those of local Tibetan children (62-07%, 2-17). The results of the dietary survey showed that dietary changes in children in Zhangmu town reduced fluoride intake, increased the intake of various nutrients and enhanced the body’s ability to resist fluorine damage. The reason for the low rate of caries in Sherpas may come from a more reasonable dietary structure. The prevalence of caries in Tibetan children comes from a sharp increase in the consumption of fine foods and sugar. Children in Sherpas, if appropriately reduced in their intake of butter tea and rakes containing brick tea, may offer a model for reducing the prevalence of dental fluorosis and dental caries in areas of brick-tea fluorosis
