Association of cardiometabolic risk factors and dental caries in a population-based sample of youths

Background: Cardiovascular disease (CVD) risk factors begin from early life and track onto adulthood. Oral and dental diseases share some risk factors with CVD, therefore by finding a clear relation between dental diseases and cardiometabolic risk factors; we can then predict the potential risk of one based on the presence of the other. This study aimed to compare the prevalence of dental caries between two groups of age-matched adolescents with and without CVD risk factors. Methods: In this case-control study, the decayed, missing and filled surfaces (DMFS), based on the criteria of the World Health Organization, were compared in two groups of equal number (n = 61 in each group) of population-based sample of adolescents with and without CVD risk factors who were matched for sex and age group. Results: The study participants had a median age 13 y 5 mo, age range 11 y 7 mo to 16 y 1 mo, with male-to-female proportion of 49/51. We found significant difference between the mean values of DMFS, body mass index, waist and hip circumferences, as well as serum lipid profile in the case and control groups. Significant correlations were documented for DMFS with TC (r = 0.54, p = 0.02), LDL-C (r = 0.55, p = 0.01) and TG (r = 0.52, p = 0.04) in the case group; with LDL-C (r = 0.47, p = 0.03) in the whole study participants and with TC in control s(r = 0.45, p = 0.04). Conclusions: Given the significant associations between dental caries and CVD risk factors among adolescents, more attention should be paid to oral health, as one of the topics to be taken into account in primordial/primary prevention of cardiometabolic disorders.
