Objective. To assess the dental status of pediatric population in Kursk and Zheleznogorsk district and correlation with the functional area of residence. Material and methods. The study involved 425 patients from 6 to 15 years old, living in regions of different radius from the Mikhailovsky Mining and Processing Plant: proximity of residence 10—30 km (n1 — group 1); 31—50 km (n2 — group 2); more than 50 km — comparison group (n3). Age subgroups were identified within the groups: children with early mixed bite aged 6—8 years (n1=45, n2=41, n3=46), children with late mixed bite aged 9—12 years (n1=48, n2=46, n3=50), children with permanent bite aged 13—15 years (n1=50, n2=48, n3=51). Results. The prevalence of caries among children is high (n2 — 89.73%; n3 — 89.12%). In the industrial risk zone, this indicator reaches 90.24%. For children of 6—8 years, there was a significant increase in the intensity of the carious process within the designated living areas: DMFT+df n1=5.6 5.4—5.8 (p<0.001) and n2=5.4 5.0—5.6 (p=0.0016) exceeds the median value of the comparison group 5.0 4.7—5.1. The level of caries resistance was also reduced with 95% probability for patients of Zheleznogorsk district: n1 — 6.1 5.8; 6.3 (p=0.0014) and n2 — 5.9 5.4;6.1 (p<0.001).There were no statistically significant differences in children of secondary school age and adolescence with the control group, but a negative trend was identified. Conclusion. The results obtained demonstrate changes in the dental status of children living near an industrially active area, which is a prerequisite for careful monitoring of their health status.
