Daily toothbrushing prevents early childhood caries, but reinforcement depends on facilitative parenting behaviours. Mother-to-infant bonding, the maternal affection towards infant, is an environmental factor that strongly influences parenting.This study examined association between bonding and children's daily frequency.The sample consisted of 83 954 mother-infant pairs at two years postpartum, derived from initial JECS (cohort study), which included 104 062 foetuses. Maternal disorders were assessed using Mother-to-Infant Bonding Scale (MIBS). After multiple imputation for missing data, a multinomial logistic regression analysis was conducted with adjustments several (eg, age delivery) child-related self-performed toothbrushing) variables.The odds ratio (95% confidence interval) low (once per day) very child frequency (<1 1.12 (1.07-1.17) 1.23 (0.91-1.66), respectively, after covariate adjustments. Furthermore, univariate general linear model showed mean MIBS scores significantly decreased as increased.The prevalence one year postpartum prospectively associated lower age.
