The problem of tooth decay in children is in the area of special attention, as the prevalence and intensity of his remains high. Scientists believe that dental disease in early childhood significantly affect the quality of life of children. It is known that the main cause demineralization of teeth is a microbial factor. But when considering the mechanisms of tooth decay in children is noteworthy variety of different risk factors, including lack of salivation, poor oral hygiene, the adverse environmental and hygienic factors and others. Thus a significant place among the risk factors given the deficit of fluoride in drinking water. Research objective. It was studying of prevalence and intensity of caries at 6-year-old children of Ternopol. The content of fluorine in drinking water in city wells doesn’t exceed 0,2 mg/l. The rationale to study the condition of the teeth in the age group of 6 years was the fact that this age is the beginning of the formation of permanent occlusion. Deficient in fluoride in drinking water can lead to disruption of mineralization of teeth and, as a result of tooth decay in permanent teeth that erupt. Methods. It examined 178 children of 6 years age. Among them was selected representative group that ac-curately represents the composition of the study population, the number of 30 children (14 boys and 16 girls) for research in these basic indicators of the intensity decay. We determined the indexes that reflect the intensity of caries of deciduous teeth (bullpen and PPC) and perma-nent teeth (KPVz and KPVp), the state of oral health indicators by Silness-loe and Stallard. Become important and research to identify children with the highest intensity of caries (NICs). The level of correlation between the intensity of dental caries and oral hygiene as measured by the coefficient of Pearson. Results and discussion. The research results are presented in Table 1, showed that the prevalence of dental caries among 6-year-olds was 75%. The intensity decay was studied separately in boys and girls, and deduced the average values for the entire group surveyed children. It was established that the average intensity of caries – 6,57 ± 0,36- are high for this age group. Thus the inten-sity of caries in boys was higher than girls. Drew attention to the fact that almost all the children were cavities in the first permanent teeth that have been known to erupt in only 6 years. Children with the highest intensity decay (NIK) accounted for nearly 37% of their average intensity decay were very high – more than 10 boys and carious lesion in one ‘s permanent molars met much more frequently (more than 3 times) than girls. Based on these results, it was concluded that 6 -year-olds living in the area of hipoftoroz, high intensity lesions tooth caries. In 37% of the highest values detected intensity decay. Conclusion. Accommodation of children in an area with low fluoride content in drinking water affects dental health, contributing to the development of caries process.
