目的:研究氟斑牙和正常牙釉质中化学成分的含量变化和分布规律。方法使用电子探针对中度氟斑牙和正常牙釉质化学成分进行定点分析。结果中度氟斑牙钙、磷丢失,镁减少,但与正常牙相比,差异均无统计学意义(P>0.05);中度氟斑牙表层钙、氟含量增加,表层下钙、氟含量减少,表层与表层下相比差异有统计学意义(P<0.05)。结论与正常牙相比,中度氟斑牙钙、磷、镁含量没有显著降低;氟斑牙表层过度矿化,表层下矿化不良;氟、镁等微量元素的微量变化可能和氟斑牙的发生相关。
目的:研究氟斑牙和正常牙釉質中化學成分的含量變化和分佈規律。方法使用電子探針對中度氟斑牙和正常牙釉質化學成分進行定點分析。結果中度氟斑牙鈣、燐丟失,鎂減少,但與正常牙相比,差異均無統計學意義(P>0.05);中度氟斑牙錶層鈣、氟含量增加,錶層下鈣、氟含量減少,錶層與錶層下相比差異有統計學意義(P<0.05)。結論與正常牙相比,中度氟斑牙鈣、燐、鎂含量沒有顯著降低;氟斑牙錶層過度礦化,錶層下礦化不良;氟、鎂等微量元素的微量變化可能和氟斑牙的髮生相關。

ObjectiveThis study aims to investigate the content and distribution of compositional elements in moderate fluorosis enamel and normal enamel.MethodsThe content and distribution of compositional elements in moderate fluorosis enamel and normal enamel is investigated using fixed point scanning with the Electron Probe Micro-Analysis (EPMA) Technique.Results The Calcium (Ca), Phosphorus (P), and Magnesium(Mg) content in moderate fluorosis enamel is lower than that of the normal enamel. However, the difference is not statistically significant. There is statistically significant increase in the calcium and fluorine content at the surface and decrease under the surface of fluorosis enamel. ConclusionCompared to the normal enamel, the moderate fluorosis enamel shows no significant decrease in the Ca, P, Mg content. However, there is excessive mineralization on the surface and lack of mineralization under the surface. The trace changes in microelements such as fluorine and magnesium might be correlated with the ccurrence of dental fluorosis.
