Comparative study of enamel demineralization of different dairy (drink) goods on the primary teeth in vitro
摘要
Abstract
Objective To compare the enamel demineralization effect of different dairy (drink) goods for providing evidence for choosing children dairy (drink) products. Methods Immerse in vitro deciduous teeth in different dairy (drink) goods (milk powder solution group;yogurt group;fruit juice milk drinks group;distilled water group) for a week, the enamel surface ultrastructure in deciduous teeth immersed in different dairy (drink) were observed and compared by scanning electron microscope. Results Three kinds of dairy products (drink) can lead to deciduous teeth enamel surface microhardness decreased (P < 0.05). Different dairy products (drink) on isolated teeth enamel demineralization degree (F=20.14, P<0.05), juice milk drinks after immersion of the enamel surface microhardness of the lowest, followed by milk powder solution group and yogurt group. Deciduous teeth with three different dairy (drink) after 1 weeks of immer-sion, the enamel surface had different degree of demineralization phenomenon, observation showed irregular enamel sur-face morphology under scanning electron microscope, the phenomena of dissolution and removal of cracks, voids and so on, partial visible appearance or honeycomb pit. Conclusion Dairy (drink) product all can lead to a variety of deciduous teeth enamel demineralization of different level fruit juice milk drinks can cause serious demineralization.关键词
