Порівняння ураженості карієсом постійних зубів дітей м. Полтава залежно від наявності проявів флюорозу

Abstract

Аналіз залежності ураженості карієсом зубів від наявності проявів флюорозу показав вірогідну відмінність поширеності та інтенсивності карієсу постійних зубів у 7 – 9-річних та 17-річних школярів і дозволив зробити висновок, що після 12-ти років інтенсивність карієсу постійних зубів у дітей із проявами флюорозу зростає дуже повільно. У зоні ендемічного флюорозу профілактику карієсу постійних зубів у першу чергу необхідно проводити тим дітям, у яких флюороз не діагностовано; Анализ зависимости пораженности кариесом зубов от наличия проявлений флюороза показал достоверное отличие распространенности и интенсивности кариеса постоянных зубов у 7 – 9-летних и 17-летних школьников и позволил сделать вывод, что после 12-ти лет интенсивность кариеса постоянных зубов у детей с проявлениями флюороза растет очень медленно. В зоне эндемического флюороза профилактику кариеса постоянных зубов в первую очередь необходимо проводить тем детям, у которых флюороз не диагностирован; A considerable amount of research has been devoted to the study of the prevalence and intensity of dental caries in regions with different levels of fluoride in drinking water. The authors convincingly proved that in children living in regions with optimal or excessive concentration of this halogen in water, caries rates are significantly lower compared with those of children living in regions with an insufficient amount of fluoride. Along with this, there are actually no studies on the prevalence and intensity of dental caries, depending on the presence of manifestations of fluorosis. The aim of our investigation is to study the prevalence and intensity of caries in permanent teeth of schoolchildren in Poltava, depending on the fluorosis manifestation. To solve this problem it was a study of 7-, 8-, 9-, 12-, and 17-years-old students in secondary schools of Poltava (1214 people). All surveyed were divided into three age groups: 7 – 9-years-old, 12-years and 17-years-old. Each age group of students consisted of two subgroups: 1 – Poltava residents without clinical signs of fluorosis; 2 – Poltava residents with fluorosis symptoms on teeth. Results and its discussion. In each age group, the children of the second subgroup had a lower incidence. The prevalence of caries in them, compared with the children of the first subgroup, was significantly less by 5% in 7 – 9 years and by 12% – at 17 years. The intensity of caries was significantly below in 2,3 times and by 2,5 times respectively. School children of 12 years haven’t significant difference caries prevalence and intensity depending on the manifestations of fluorosis on the teeth (p> 0,05). Analysis of caries depending on the age showed that in the first subgroup examined that the prevalence of dental caries in 7 - 9 years was 9,42%, is likely to increase by 52% to 12 years and by 21% – from 12 to 17 years. The intensity of caries in 7 – 9 years was 0,16, significantly increased in 8 times up to 12 years and 2,2 times – from 12 to 17 years. Among children, the second subgroup likely increase in the prevalence of dental caries was 50% from 7 - 9 to 12 years and 16% - from 12 to 17 years. The intensity of caries from 7 - 9 to 12 years was significantly increased by 16 times. Between students of 12 and 17 years old we didn’t found a significant difference of intensity of caries (p> 0.05). Analysis of the relationship of caries manifestations of the presence of fluorosis showed a significant difference between the prevalence and intensity of caries in permanent teeth in 7 – 9 years old and 17 years old schoolchildren and led to the conclusion that after 12 years the intensity of caries of permanent teeth in children with manifestations of fluorosis grows very slowly. Conclusions. In the area of endemic fluorosis, the prevention of caries of permanent teeth should first of all be carried out for those children whose fluorosis is not diagnosed.
