| 摘 要： | 目的研究食醋对乳牙牙釉质的超微结构的作用。方法采用微量化学分析法检测食醋处理乳牙牙釉质后食醋中钙含量的变化。采用维氏显微硬度仪测定经食醋涂擦后乳牙牙釉质表面显微硬度的变化。结果食醋能导致乳牙牙釉质钙溶出和表面显微硬度下降,随时间延长钙溶出减少,表面显微硬度降低的程度减弱。结论食醋对乳牙牙釉质具有脱矿作用并可使釉质表面显微硬度降低。

| Abstract: | Objective To research the deciduous enamel demineralization caused by vinegar.Methods The calcium in the vinegar was analyzed by UV spectrophotometry,and then the deciduous enamel was immersed in vinegar.And the clcium in the vinegar was analyzed by EL 312e microplate.The enamel surface microhardness was measured by a microhardness tester.Result The vinegar had demineralizing effect on deciduous enamel and decreased the surface microhardness of deciduous enamel.Conclusion The vinegar may have erosive effect on deciduous enamel. |
