Studies show that the morbidity of children on caries of the teeth is regional and depends on a number of factors, both local and general. Volyn region is characterized by separate territories exposed to radioactive loading, man-made pollution and relatively clean territories. At the same time, the dental morbidity of children in the region is not suffi ciently highlighted.The aim of the study – to assess the dental caries infrequency in children living in areas with different ecological contamination.Materials and Methods. This publication presents the results of a stomatological examination of 918 children of the Volyn region. Among the surveyed were 611 children living on the territory affected by radioactive contamination due to the accident at the Chernobyl Nuclear Power Plant (Liubeshiv and Manevychi) and 307 children living on the territory of man-caused loading due to coal emissions (Novovolynsk). The examinations were conducted in age groups 7, 12, 15 years in accordance with WHO guidelines for epidemiological studies. The teeth were damaged by caries according to the following indices: prevalence of caries of teeth (in %), caries intensity according to KFR indices (K - caries, F - fi lled, R - removed tooth).Results and Discussion. The prevalence of dental caries among children of radioactive contaminated areas of Manevychi and Liubeshov is, on average, (86.91±1.95) % and (87.58±1.89) %, and Novovolynsk (93.14±1.45) %, which is a rather high indicator, according to WHO criteria. The analysis of KFR indices showed that the intensity of tooth decay by caries of children of Novovolynsk is (4.60±2.60) tooth, which is signifi cantly lower in relation to children from radiation-contaminated areas (mean KFR=(5.36±3.77) tooth and (4.78±3.42) tooth respectively).Conclusions. The obtained results of tooth decay by caries show insuffi cient level and untimely oral sanitation, and the absence of preventive measures.
