PREVALENCE OF DENTAL CARIES AND CHRONIC CATARRHAL GINGIVITIS IN SCHOOL-AGE CHILDREN IN DIFFERENT REGIONS OF UKRAINE

Abstract

Actuality. The study of the prevalence of dental caries and chronic catarrhal gingivitis (CCG) in schoolage children living in different regions of Ukraine is necessary to identify risk factors for their simultaneous development and to develop regionally targeted sets of preventive measures. The purpose of the study is to determine the prevalence of dental caries and CCG in school-age children living in the cities of the central and northern regions. Materials and methods. 503 children aged 7 to 15 years old were examined, among them 150 children (29.2%) were examined in the city of Vinnytsia (central region), 148 children (29.4%) in the city of Chernihiv (northern region), and 148 children (29.4%) in the city of Kyiv (northern region) – 205 children (40.8%). We determined the prevalence of dental caries and CCG in children 7-8 years old, 12-13, and 15 years old, according to WHO recommendations. The results. The prevalence of dental caries in children 7-8 years old in Vinnytsia was 81.3±4.5%, in Chernihiv – 89.5%±4.9%, in Kyiv – 89.6±4.4%, in children 12-13 years old, according to the list of cities, – 68.0±5.4%, 80.8±7.7% and 89.7±3.1±%, in 15-year-old children living in Chernihiv, the prevalence of caries was 94.8±2.9%, in Kyiv – 86.7±4.2%. The prevalence of CCG in Vinnytsia among children aged 7-8 was equal to 18.7±4.5%, among children aged 12-13 – 36.0±5.5%, in Chernihiv – 31.6±7.5% and 40, 4±6.0%, in Kyiv – 22.9±6.1% and 43.3±5.0%, respectively. Among 15-year-old children in Chernihiv, the indicator was 51.7±6.1%, in Kyiv – 55.0±6.4%. Conclusion. Differences between the prevalence rates of dental caries and CCG in school-aged children, depending on the region, may be related to natural, geographical and environmental factors. Established correlations between disease prevalence indicators indicate their likely associated course and the need to develop complex preventive programs taking into account both monoand associated course, age characteristics and regional focus.
