Serum 25-hydroxyvitamin D levels are associated with dental caries experience in Korean adolescents: the 2010 ~ 2014 Korean National Health and Nutrition Examination Surveys / 한국영양학회지

ABSTRACT

PURPOSE: This study was conducted to evaluate the association between serum 25-hydroxyvitamin D (25(OH)D) levels and dental caries experience in Korean adolescents based on the 2010 ~ 2014 Korean National Health and Nutrition Examination Surveys. METHODS: The study subjects were 2,655 Korean adolescents aged 10 to 18 years. Subjects were classified into four groups according to their serum 25(OH)D levels. We used logistic regression to evaluate the relationship between vitamin D and for dental caries experience after adjusting for age, household income level, recipient of basic livelihood, tooth brushing and visiting dental clinics. RESULT: Multiple logistic regression analysis showed that serum 25(OH)D insufficiency (20 ng/mL≤25(OH)D<30 ng/mL) was associated with increased odd ratios (ORs) for dental caries experience in boys (OR = 2.577, 95% CI = 1.013–6.557), compared with serum 25(OH)D sufficiency (25(OH)D≥30.0 ng/mL). CONCLUSION: The serum 25(OH)D levels were found to be related to risk of dental caries experience in Korean adolescent boys.
