微量元素与地方性氟中毒的关系较为密切,目前研究的越来越多,氟与微量元素间的相互作用,是氟研究进展中的重要课题。因此,对42例氟中毒儿童与31例健康儿童发中铜、铁、锌进行了测定。对结果进行对比分析,探讨这些微量元素在儿童氟斑牙的发生发展过程中的变化和作用。1 对象和方法 根据《地方性氟中毒防治手册》的诊断标准,在镇赉县选择42例饮水型氟斑牙儿童,在白城市选31名健康儿童作对照。年龄均在8～14岁。样品取后枕部头发,常规方法处理。发中铜、铁、锌含量用原子吸收分光光度计(日本岛津AA-670型)火焰方法测定。发氟用碱熔灰化——氟电极法测定。
Trace elements and the relationship between endemic fluorosis is more close, the current more and more research, the interaction between fluorine and trace elements, fluorine research is an important issue in the progress. Therefore, 42 cases of fluorosis children and 31 healthy children hair copper, iron, zinc were measured. The results were compared and analyzed to explore these trace elements in the occurrence and development of children’s dental fluorosis changes and role. 1 Subjects and Methods According to the diagnostic criteria of “Handbook of endemic fluorosis”, 42 cases of drinking water dental fluorosis children were selected in Zhenlai County and 31 healthy children were selected as control in Baicheng City. All ages are 8 to 14 years old. Take the occipital hair samples, the conventional method of treatment. Hair copper, iron, zinc content by atomic absorption spectrophotometer (Japan Shimadzu AA-670 type) flame method. Determination of fluoride with alkali ash - fluorine electrode method.
