Role of Fluoridation in Caries Prevention among Children- Long Term Follow-Up

It is known that fluoride spray application is an effective method of preventing dental caries permanent dentition. Material and methods Our research of 355 school children 12 years old showed that use the spray preparation of fluoride 5 % Sodium Fluoride 22.600 ppm had a remarkable anti-caries effect. In a control group we had 198 school children, girls 40.4 % and boys 59.6 %. In fluoridation group we had 157 school children, girls 40.1 % and boys 59.9 % of the same age. Resultants Ninety percent of examined children had caries. DMFS (decayed, missing and filled surfaces) were from the data analyses we see that in the control group at the beginning of the study the index DMFS =4.5 while at the end of the study the index increases DMFS = 5.27. The fluoridation group at the beginning of the study presents a caries experience DMFS = 4.2 and at the end of the study DMFS =4 decreased respectively. Comparison of averages of DMFS at the end of study between control group and fluoridation group have shown the reduction of caries (pless than0.05). Conclusion The fluoride spray 5 % NaF resulted effective in reduction of dental caries of permanent teeth in school children.
