Maternal bonding disorders were assessed using the Mother\u2010to\u2010Infant Bonding Scale (MIBS). After multiple imputation for missing data, a multinomial logistic regression analysis was conducted with adjustments for several maternal (eg, age at delivery) and child\u2010related (eg, self\u2010performed toothbrushing) variables.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The odds ratio (95% confidence interval) for the association of maternal bonding disorders with the low (once per day) and the very low child toothbrushing frequency (&lt;1 per day) was 1.12 (1.07\u20101.17) and 1.23 (0.91\u20101.66), respectively, after covariate adjustments.
