| Objective:To children’s teeth caries in multiple age, most children failed to timely treatment, not only the serious influence children’s dental health, not a good chewing function, also have an impact on the child’s pronunciation, influence children’s psychological health. If you want to the child to health of body and mind, will take active treatment of preventive measures. Reduce the caries of deciduous teeth caries rate, it has far-reaching influence. In this paper, a preliminary understanding of jiamusi five district kindergarten, for 3-5 years old children, investigation of caries of deciduous teeth. In the children’s oral health problems prevent progress, provide effective help. And research by many.Application of love, baby teeth enamel resistance to acid corrosion effect of carbonated soft drinks, hope to provide more drugs for the prevention of dental decay, as well as the guiding thinking.Methods :1, March 2013 by random, cluster and multi-stage extract form freely choose five in jiamusi area: forward area, xiangyang area, east area, Yong Gong area, suburb. Each area selected kindergartens, sequentially, the kindergarten number, will be selected in each area, at a good number of kindergarten, the selection of a random. The seco nd stage, with the method of cluster sampling, in the kindergarten in the smoke, random, selection of 480 for 3 to 5 years old children take strict check teeth. Using SPSS17.0 software to check the results using X2 test analysis. 2, at the same time to collect in jiamusi university oral of the patients with dentist, the children’s dental disease of hospital for baby teeth stuck appropriated 72 front teeth. 72 baby teeth test specimen willbe random divided into four groups, each group of 18. Artificial saliva as the control group(A); Cola carbonated drinks immersion group(B); Coke soak more joy fluoride treated group(C); Fluoride foam processing after coke soak group(D), group A specimen processing, not at 37 degrees Celsius in artificial saliva 4 min, remove with deionized water is rinsed clean, again in the artificial saliva. 12 h to replace a artificial saliva; With coke bubble group B specimen for 30 minutes, washed out after use to ion water from coke, still place about 4 min, natural drying. Once again into the coke soak 30 min, the entire process cycle to 12 h. Experimental group C more fluoride group, the tooth surface is dry, the more love with special xiaomao brush in specimens of enamel surface area, about 4 min, natural drying, and then put daub after enamel block in coke soak 30 min, rinse out with clean. Natural drying. Again, so until 12 h. D fluoride foam group, make the tooth surface is dry, the foam coated in enamel fluoride exposure area, after about 4 min, use air gun to blow open fluoride foam, natural drying, and then put dry enamel block in coke soak 30 min, rinse out with clean, dry naturally. Again, so until 12 h. The specimen using the spectrum analyzer detection demineralization of calcium phosphate on the surface of the teeth, scanning electron microscope and microhardness meter to confirm le fluorine can prevent more cola drinks in teeth enamel demineralization. To observe the result of the experiment have differences, to 12 hours, so that we can increase the acid treatment process, finally get the results to gap is bigger. The same cycle of 12 h is consistent with oral feeding frequency, refers to the acidic food.Results :the 1, 480, 222 people suffering from dental caries in children with caries rate was 46.25%, caries(XDMFS) 4.62, caries(XDMFT) 3.06, caries filling rate is 9.7%.2(1) energy spectrum analysis results show that compared with group A, coke soak out can make A tooth hard tissue demineralization, calcium phosphate value; After the tooth crown surface coated fluoride on the surface of the enamel demineralization of degree decreased, increasing particle size of crystal increases, enamel Ga2 +, P3 + proportional decline degree, soaking cola carbonated drinks group than coke soak le fluoride, fluoride foam processing after processing high coke soak group, the difference was statistically significant(P < 0.05).(2) the microhardness value, the result shows: the experimental group read values between the comparison, the difference had statistical significance(P < 0.05). Group B in the carbonated drinks after soaking microhardness decreased obviously, the data values change significantly. Coke soak more fluoride treated group, fluoride foam processing after coke soak group of microhardness is slightly lower.(3) scanning electron microscopy showed that artificial saliva group(A) scanning electron microscopy observation of enamel surface flat, form A complete, glaze column is not broken, form clearly. Cola carbonated drinks immersion group(B) were observed under electron microscope, enamel surface shape is irregular, observed under 1000 times to the present the reticular structure of large sizes, aperture shape. Visible even designed structure, center and glaze glaze column spacing is clear. Much love coating after soaking carbonated drinks group(C) electron microscope enamel surface is more complete, demineralization of pore, 2000 times and observed under most of the area is white in the mineralized matter deposition. White sediment sizes. Fluoride foam coating after soaking carbonated drinks group(D) scanning electron microscopy(sem) observation, the enamel surface demineralization of mesh pore space is obvious, visible glaze under 2000 times column form is incomplete, but also in a small amount of mineral deposits. But not as good as group C.Conclusion: jiamusi 1, 3-5 years old preschool children caries level is higher, need to carry out and strengthen early prevention, improve the caries disease treatment.2 more fluoride can inhibit baby teeth enamel demineralization in carbonated drinks, effect is good, and can promote its mineralization.3 more fluoride can’t completely in inhibitory effect of carbonated drinks on enamel demineralization. |
