PREVALENCE OF CARIES OF PERMANENT TEETH IN CHILDREN AGED 6–12 YEARS WITH DENTOALVEOLAR ANOMALIES

Abstract

Today, the prevalence of permanent tooth decay and dental anomalies among children is high worldwide and in Ukraine in particular, and has no tendency to decrease.Many scientific studies show a link between these dental pathologies. However, there are also studies that have found contrary results that do not support this link.Therefore, these diverse data encourage us to conduct further research to assess the condition of the hard tissues of permanent teeth in children aged 6-12 years with dentoalveolar anomalies. Research methods. To achieve this goal, 119 children aged 6-12 years with dental caries (main group) and 103 children of the same age (comparison group) who studied at the O. Kovch Przemysl secondary school were examined in the dental department of the Municipal Enterprise «Przemysl Central District Hospital». The children were examined in accordance with the main provisions of the Declaration of Helsinki for Biomedical Research (Seoul, 2008) with informed parental consent. The prevalence of caries was determined in%, and the intensity of caries was determined by the CPV index. The study results were statistically analysed using the Student's t-test. Scientific novelty. As a result of the study, it was found that in children with PJD the prevalence of caries of permanent teeth, on average, was 89.92±2.76% with an intensity of 3.22±0.34 teeth, and in children without PJD – 78.64±4.04% and 1.96±0.26 teeth, respectively. The highest prevalence of caries in permanent teeth was found among girls aged 9-12 years with GPA (96.87±3.08%), and the lowest among boys aged 6-8 years without GPA (68.00±9.33%). It was found that the intensity of caries of permanent teeth in 6-8-year-old children with VHD was 34.18% higher than in children without VHD. Among 9-12-year-old children, this difference was 41.52%. It was found that from 6-8 years to 9-12 years, the value of the CPV index in children with TMD increased by 2.28 times, and in children without TMD by 2.03 times. It was found that in both groups of children aged 6-8 years and in 9-12 years old children without dental caries, the number of carious unsealed teeth was 52.31%, 18.57% and 61.49% higher than the number of sealed teeth. In contrast, in 9-12-year-old children with dental caries, the number of filled teeth was 42.08% higher than the number of carious teeth. Conclusions. The results of the study indicate a higher level of caries in permanent teeth in children with TMD compared to children without TMD, which indicates a possible relationship between these dental pathologies. The high intensity of caries of permanent teeth in the examined children indicates an insufficient level of sanitation and the need to motivate parents and children to maintain dental health.
