Analysis of the prevalence and intensity of caries in children living in Moscow, aged 6-9 years, according to preventive medical examinations

Aim. To study and analyze the prevalence, intensity of caries in children during the period of early mixed dentition (6-9 years) depending on age and gender. Materials and methods. In accordance with the goal, an epidemiological survey of the child population was carried out as part of preventive medical examinations of minors to study dental morbidity in children aged 6 to 9 years in Moscow. Clinical research methods were used to determine the dental status of the examined children. The results of the survey were processed statistically. Conclusions. The prevalence of caries in children aged 6-9 years corresponds to the average level in all age periods, for both sexes. The index of caries intensity at the age of 6 years in boys is higher than in girls (p = 0.013), at the age of 7 and 8 years, boys and girls have a similar caries intensity (p = 0.6), at 9 years old, girls have a higher caries intensity (p < 0.0001). In boys, there is no statistically significant difference in the index of caries intensity depending on age (p = 0.064), in girls there is a tendency towards an increase in the caries intensity index (p < 0.0001). In all age periods, the “с” and “С” components prevail in the structure of the caries intensity index, and this component is higher in girls than in boys. The indicator "f" and "F" in all age periods is higher in boys than in girls. © 2022, Endo Press LLC. All rights reserved.
