TIMING OF CARIES LESION DEVELOPMENT (early vs. late vs. none)	Odds Ratio
	(95% CI)	p-value
Surgency	1.13 (0.67, 1.92)	0.642
Negative Affect	1.00 (0.98, 1.02)	0.808

^*OR=Odds Ratio.

^**IRR=Incidence Rate Ratio.

^***d3mfs, d4mfs, and d5mfs are dmfs scores calculated using ICDAS severity scores ≥ 3, ≥ 4, or ≥ 5 to define the decay portion of dmfs.

Covariates included in all models were Medicaid status, child race/ethnicity, frequency an adult brushes the child’s teeth, sleeping while nursing or while drinking something other than water from a bottle/sippy cup, frequency drinking tap water, frequency of sugary drinks, caregiver cavities/fillings/teeth pulled in last two years, frequency caregiver’s gums bleed while brushing.
