Summary
This cross-sectional study of 156 Spanish adolescents (aged 15) examined associations between dietary nutrient intake and periodontal health status using the WHO CPI and 24-hour dietary recall. Adolescents classified as periodontally healthy demonstrated significantly higher intakes of dietary fibre, magnesium, selenium, and vitamins A and C compared to those with periodontal disease, suggesting that micronutrients with antioxidant and anti-inflammatory properties may support periodontal health during adolescence.
Regional applicability
Whilst conducted in Spain, the findings are potentially applicable to United Kingdom adolescents, as the study population and methodologies align with UK dental epidemiology practice. The emphasis on nutrient-dense dietary patterns to support oral health may inform UK public health guidance for adolescent dental care and nutrition, though UK-specific validation would strengthen recommendations.
Key measures
Periodontal status (Community Periodontal Index; CPI); dietary nutrient intake (24-hour dietary recall); fibre, magnesium, selenium, vitamin A, and vitamin C intake; presence of periodontal disease (affected sextants)
Outcomes reported
The study measured the association between dietary nutrient intake (fibre, magnesium, selenium, vitamins A and C) and periodontal disease status in adolescents aged 15 years, assessed using the Community Periodontal Index. Adolescents with healthy periodontal status had significantly higher intakes of several micronutrients with antioxidant and anti-inflammatory properties.
