Outcomes measure	SDF	FV	P value
Primary outcome
Caries incidence
Mean new decayed surface (n = 434 children)	0.4 ± 1.5 (n = 209)	0.4 ± 1.3 (n = 225)	.65*
Odds ratio (95% CI) of decayed surface incidence (n = 10,071 tooth surfaces in total)	0.99 (0.59–1.64) (n = 4880)	1 (reference) (n = 5191)	.96#
Odds ratio (95% CI) of decayed surface incidence (n = 10,071 tooth surfaces, adjusted for baseline dmft)	1.15 (0.66–2.00) (n = 4880)	1 (reference) (n = 5191)	.62#
