Notes: OR: odds ratio; CI: confidence interval; DMFT: missing and filled teeth; * Adjusted for knowledge about shokuiku, an irregular diet, frequent snacking and/or eating at night, frequent consumption of sugar-sweetened soft drinks, regular dental checkups, tooth brushing (daily frequency), dental floss (usage), fluoride dentifrice (usage), and DMFT scores at baseline. P-value for interaction was 0.018.
