Summary
Dental caries declined significantly across Nordic countries over two decades, with Iceland showing a later but steeper reduction. While fluoride and public programs were key, caries have not been fully eradicated.
Area of Science:
- Dental Public Health
- Epidemiology of Oral Diseases
Background:
- Dental caries prevalence has historically varied across Nordic nations.
- Understanding trends in dental caries is crucial for public health policy.
Purpose of the Study:
- To analyze and compare the trends in dental caries decline in Denmark, Finland, Iceland, Norway, and Sweden over the past two decades.
- To identify factors contributing to the observed changes in dental caries rates.
Main Methods:
- Analysis of public dental health reports and data from Denmark, Finland, Iceland, Norway, and Sweden.
- Comparison of caries-free percentages and mean DMFT (Decayed, Missing, Filled Teeth) in 12-year-old children over time.
Main Results:
- A consistent decline in dental caries observed in Denmark, Finland, Norway, and Sweden over the last 20 years.
- Iceland exhibited a later onset of decline but a more rapid reduction in dental caries compared to other Nordic countries.
- In 1991/92, 23-49% of 12-year-olds were caries-free, with a mean DMFT of 1.2-2.5.
Conclusions:
- Fluoride interventions and public dental health programs have been instrumental in reducing dental caries across the Nordic region.
- While caries prevalence has decreased significantly and been delayed, complete eradication has not been achieved.
