The analysis of dental morbidity in children living in four populated areas of the city, located on the border of the sanitary protection zone (zone I), at a distance of 3 km (zone II), 10 km (zone III) and 15 km (zone IV) from petrochemical complexes. Of the surveyed children, 102 (15.2%) showed good physical development, 412 (61.6%) - satisfactory and 155 (23.2%) - deteriorated. The prevalence of dental caries was 18.6 ± 3.5%, 24.0 ± 2.1% and 30.3 ± 3.7%, respectively. The difference is statistically significant between the indicators of groups of children with good and impaired physical development (P <0.05). Accordingly, the intensity of caries lesions was 3.1 ± 0.4; 3.7 ± 0.1 and 4.9 ± 0.6 among children with carious teeth.
