ABSTRACT
Prevalence and intensity of caries in both primary and permanent teeth is still an actual children’s problem. It is known that caries destruction of temporary teeth contributes to the rapid development of this process in permanent teeth. The prevalence of caries in school-age children’s permanent teeth in reaches 54%, and in 97.5% of cases the first molars are affected.
The aim of the study. This study was aimed to access the prevalence and intensity of dental caries using the DMFT, dmft, DMFT + dmft indices, as well as to evaluate the structure of these indices of preschoolers and primary school children in Minsk.
Objects and methods. Dental examination of 220 children aged from 5 to 7 years was carried out.
Results and discussion. The prevalence of caries among these children was 82,7 ± 2,55%, with a mean number of decayed, missing and filled teeth of 5.51 (SD 3.90). In primary dentition, the caries prevalence was 82,3% ± 2,57%, and the mean dmft score was 5.16 (SD 3.65). In permanent dentition, the caries prevalence was 16,82 ± 2,52%, the mean DMFT score was 0.35 (SD 0.90).
Conclusion. Thus, preschoolers and primary school children have a high activity of dental caries, which corresponds to the data of an epidemiological survey of children in the Republic of Belarus. A significant proportion of permanent teeth with caries in the structure of the dental caries intensity index was revealed. The results indicate the need of preventive measures against the progression of children’s caries.
