Evaluation of caries preventive measures

Area of Science:

• Pediatric Dentistry
• Public Health Research
• Adolescent Health

Background:

• A cohort of 3373 12-year-olds was established in 1995 to evaluate preventive dental measures.
• A high-risk group was identified for targeted interventions and detailed monitoring.
• The study aims to assess the long-term impact of various preventive programs on adolescent oral health.

Purpose of the Study:

• To evaluate the effectiveness of different preventive dental programs in a high-risk adolescent group.
• To investigate the relationship between demographic data, social background, lifestyle, and oral health behavior.
• To establish a representative cohort for longitudinal oral health research in Swedish adolescents.

Main Methods:

• Randomized controlled trial design with four intervention groups for the high-risk cohort.
• Longitudinal follow-up examinations every year for the high-risk group and every other year for the whole cohort until age 18.
• Data collection includes clinical dental examinations (DMFT index) and biennial questionnaires on social, lifestyle, and health behaviors.

Main Results:

• Baseline analysis confirmed the study group's social distribution mirrors the general Swedish population.
• The mean Decayed, Missing, and Filled Teeth (DMFT) score was 1.5, consistent with national figures for 12-year-olds.
• High inter- and intra-examiner reproducibility (0.78 and 0.82) for caries diagnostics indicates reliable data collection.

Conclusions:

• The study cohort is representative of 12-year-old adolescents in Sweden.
• Findings from this project are likely generalizable to the broader Swedish adolescent population.
• The study provides a robust foundation for evaluating preventive strategies in adolescent oral health.
