Demineralization of the different sites of the first permanent molar was evaluated by KaVo DIAGNOdent. The effect of FD and FII in toddler period on demineralization of the first permanent molar was evaluated.Early demineralization of the first permanent molar in children without fluoride drop were more severe than that of children with fluoride drop in toddle period (P < 0.01).
