目的 了解南海市南庄镇和小塘镇人群人体氟含量 ,作为制订防龋计划的依据和防龋项目评价的基线资料。方法 在两镇收集临床拔除的恒牙 ,粉碎、扩散 ,吸收、洗出、定容 ,用氟离子选择电极测定氟含量。结果 南庄镇人群恒牙氟含量为 (2 32 .5 3± 71.73)mg/kg ,小塘镇人群恒牙氟含量为 (2 30 .14± 87.87)mg/kg。两镇人群恒牙氟含量比较差异无显著性。结论 南海市南庄镇和小塘镇均未发现人群恒牙氟含量异常现象。
Objective To understand the fluorine content of human body in Nanzhuang Town and Xiaotang Town, Nanhai City as the basis for formulating the anti-caries plan and the baseline data for the evaluation of anti-caries project. Methods The permanent teeth were collected from two clinics and were crushed, diffused, absorbed, washed out and fixed volume. The fluorine content was determined by fluoride ion selective electrode. Results The content of fluorine in permanent teeth of Nanzhuang Town was (2 32.5 ± 71.73) mg / kg, and that of Xiaotang Town was (2 30.14 ± 87.87) mg / kg. There was no significant difference between the two groups of permanent population fluorine content. Conclusion Nanzhuang Nanzhuang Town and Xiaotang Town have not found abnormalities of fluorine content in permanent population.
