Summary

Dental caries levels remain high in Baltic states, resembling Nordic countries decades ago. Despite declines in Nordic countries, vigilance is needed to prevent future adult caries, highlighting the importance of effective oral hygiene and fluoride use.

Area of Science:

  • Dental Public Health
  • Epidemiology
  • Pediatric Dentistry

Background:

  • Many European countries meet the World Health Organization's goal for 12-year-olds' decayed, missing, or filled teeth (DMFT) of ≤3.
  • The Baltic states (Latvia, Lithuania, Estonia) exhibit high caries prevalence in 12-year-olds, with DMFT scores ranging from 4.6 to 5.8.
  • Caries levels in Baltic states mirror those in Nordic countries from 20 years prior, suggesting potential for similar public health interventions.

Purpose of the Study:

  • To assess current dental caries prevalence in Baltic states.
  • To compare Baltic caries data with historical Nordic data.
  • To highlight the need for improved oral hygiene and fluoride access in the Baltic region.

Main Methods:

  • Analysis of recent epidemiological survey data on caries prevalence in 12- and 15-year-old children in Latvia, Lithuania, and Estonia.
  • Comparison of current Baltic caries data with historical data from Nordic countries, including Iceland and Sweden.
  • Review of factors such as oral hygiene practices, fluoride dentifrice use, and dental care privatization.

Main Results:

  • Mean DMFT for 12-year-olds in Latvia, Lithuania, and Estonia was 5.8, 4.9, and 4.6, respectively.
  • Fifteen-year-old Latvians and Lithuanians averaged 8.1 and 7.0 DMFT, potentially underestimated due to lack of radiographic examination.
  • Follow-up studies in Iceland showed significant caries decline (52-66%) over 7 years, yet caries experience remained high.
  • While caries is shifting to pits and fissures in younger children, approximal lesions are prevalent in older adolescents and young adults in Nordic countries.

Conclusions:

  • High caries prevalence in Baltic states necessitates urgent public health interventions.
  • The effectiveness of fluoride dentifrice use appears limited by poor oral hygiene in the Baltic region.
  • Continued monitoring and preventive strategies are crucial in Nordic countries to address emerging trends like approximal caries and prevent future adult dental issues.
