A bstract — The enamel solubility reducing characteristics of four fluorides — sodium fluoride (NaF), acidulated phosphate fluoride (APF), stannous fluoride (SnF 2 ), and sodium monofluorophosphate (Na 2 PO 3 F), each prepared to contain 1.23 per cent F are evaluated. Initial solubility reduction by SnF 2 , 81.7 per cent was significantly (P < .01) higher than that of 76.9 per cent provided by APF, however, after repeated exposure to acid etches the protection by APF became significantly (P < .01) higher than that derived from SnF 2 . The durability of protection provided by SnF 2 after overnight washing, was significantly (P < .01) higher than that of APF. Results for NaF and MFP were significantly (P < .01) lower than those of either APF or SnF 2 at any point in the experiment.
