Abstract (English):
Subject. The results of a retrospective analysis of the prevalence and intensity of major dental diseases in school children are presented. The goal is to determine the prevalence and intensity of major dental diseases in students aged 7, 12 and 15 years. Methodology. The study involved 310 children aged 7 to 15 years, studying at school number 165 in Kazan. A clinical study was conducted by dental examination. An outpatient card was set up for each student, in which the results of a dental examination were recorded. Statistical analysis of the results of the study was carried out using a standard statistical software package for Microsoft Office Excel. Results. The most common dental diseases in children are tooth decay and periodontal disease. The prevalence of dental caries averaged 83.2 %, the intensity — 3.7 ± 0.12 for CPP + CPU. According to the WHO classification, the prevalence of caries of permanent teeth in 12-year-old children is at an average level (75.6 %) with a low level of caries intensity (2.51 ± 0.1). The component K dominates in the structure of the intensity index (1.52 ± 0.1). In 15-year-old schoolchildren, the prevalence of caries is at a high level (87.5 %) with an average level of intensity (4.38 ± 0.1). The “P” component (2.24 ± 0.1) predominates in the structure of the intensity index and the “U” component (0.12 ± 0.1) appears (p <0.05). The prevalence of signs of periodontal disease in primary school children was 3.3 %, in children 12 years old —22.1, 15 years old — 29.0. Conclusions. The results of the study indicate a low level of dental care, the lack of preventive and therapeutic measures among students of key age groups. The data obtained are aimed at substantiating the main directions of improving dental care for schoolchildren in modern conditions of the healthcare system.
