[The integral analysis of children's dental health by the factor of the living functional area (on the example of the Kursk Region)].

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.
