[Longitudinal study of the primary prevention effect on dental caries].

Aim: Assessment of the dental caries prevalence among 12-year-old children in Belarus and Russia and evaluation a possible effect of the primary prevention programs on oral health in adult population.

Methods: Meta-analysis of the world dental literature and study of the descriptive epidemiology data on the prevalence of dental caries among key age groups of children, adolescents and adults using earlier study data carried in Minsk and Moscow and within the intercountry scientific project using the EGOHID system in 2013-2017 yrs.

Results: Analysis of the epidemiology data on the DMFT of 12-year-old children in the last 40-50 years suggested a trend of the reduction of dental caries prevalence in Belarus and Russia by 10-15%.

[The feasibility of descriptive epidemiology in assessments of dental caries disease in children in Russia and Belarus].

Aim: this study aims to estimate significance of the descriptive dental epidemiology in evaluation of the long-term effect of the Community program for prevention of dental caries.

Methods: The descriptive dental epidemiology data of DMFT 12-year-old children in Belarus and Russia were analyzed since 1961 to 2014.

Results: Meta-analysis of publications indicated that prevalence of dental caries has dropped from average 3.

5.1 The demography of oral diseases, future challenges and the implications for dental education.

This Section considered the immense challenges presented by the changing demography of populations (in particular, cross-boundary flow), changing oral and dental disease trends. It also considered the difficulties of gathering data on such information. It then considered how these challenges may affect the education of the dental team in the future.

Assessment of periodontal status by CPITN and its applicability to the development of long-term goals on periodontal health of the population.

CPITN data from 40 countries have been used to assess periodontal status at ages 12, 15 and 35-44 years. There are broad differences in the numbers of healthy sextants between developing countries and those which are highly industrialized. At 12 years this component of the Index could provide the basis of a global indicator of periodontal health--not less than 3 healthy sextants per child by the year 2000.
