Effect of the Fluoride on Inhibition of Enamel Demineralization-Clinical Success

. Aim To investigate the effect of preventive local method of fluoride spray application in dental caries of permanent dentition. Materials and methods For the permanent dentition treatment of the age group 12 years old we used the spray preparation of fluoride 5 % Sodium Fluoride. In the control group we had initially 198 individuals, 80 females (40.4 %) and 118 males (59.6 %). In the fluoridation group we had 157 individuals, 63 females (40.1 %) and 94 males (59.9 %). Results. Statistical analysis showed significant difference between control group and fluoridation group before and after fluoride treatment. The values of (pless than 0.05) were statistically significant. The mean of caries experience for the sample in the control group is DMFT = 2.9. The mean for the caries experience for the sample in the fluoridation group was DMFT =2.7. The mean of caries experience for the sample in the control group in the end is DMFT = 3.07. The mean experience of the caries in the sample in the fluoridation group is DMFT = 2.33. In the fluoridation group we notice a decrease of the mean value of DMFT index from 2.7 to 2.33. The data collected from the applications and was analyzed on statistical program SPSS 18. Conclusion. The results obtained in the present study showed that use of fluoride spray affectivity inhibit the risk of caries disease of the children under experimental conditions.
