Study of the effect of fluor protector on resistance to demineralization of milk beverages on enamel of primary teeth

Abstract

Abstract: PUPPOSE: To study the effect of fluor protector against demineralization of deciduous teeth enamel surface in milk beverages, to certify the mechanism of anti-demineralization of fluor protector, and provide laboratory basis for clinical practice of fluor protector and the prevention of infants and young children. METHODS: The enamel surfaces of 30 prepared deciduous teeth without caries were randomly divided into 3 groups. Group A was control group. Milk beverages were used in group B, and 0.1% fluor protector was used in group C. Each group included 10 specimens. All specimens were soaked in water tank at 37℃ for 4 days, but specimens in groups B and C were soaked at intervals in 10mL yogurt drinks in water tank at 37℃, 9 minutes for one time and 3 times for one day. Scanning electron microscope (SEM) and spectrum analyzer were used to detect the changes in surface morphology of deciduous teeth enamel surface. The concentration values and the ratio of calcium / phosphorus were analyzed with SPSS11.5 software package. RESUITS: Enamel soaked in milk beverages had decreased Ca^{2 +}and P^{3 +} content significantly (P<0.01). Ca^{2 +}and P^{3 +} content in enamel in group C was significantly higher than in group B (P<0.01). Scanning electron microscopy showed enamel surface in group C had mild demineralization. CONCLUSIONS: Milk beverages can cause a strong acid demineralization in deciduous teeth enamel surface. The application of fluor protector in enamel surface can inhibit enamel demineralization in the milk beverages.
