The aims of the present study were: 1) to compare the fluoride uptake by enamel from F-milk with that from F-water; 2) to compare the systemic and topical effect versus topic effect alone; 3) to determine the fluoride uptake by demineralised compared with sound enamel, as well as the fluoride uptake by enamel from fluoridated milk, compared with fluoridated water. 102 paired enamel slabs (half demineralized and half sound, and half on each slad varnished and half exposed) were fitted on lower intraoral appliances of 17 subjects for 3 weeks (4 samples on each subject each week). They were kept in the mouth 24 hours a day, except eating and toothbrushing. The 3 experimental periods were: a) 100 ml of 5 ppm F-milk were rinsed in the mouth, then drunk between meals 4 times a day - 400 ml daily; b) 100 ml of 5 ppm F-milk were rinsed in the mouth and then expectorated 4 times a day; c) 100 ml of 5 ppm F-water were rinsed around the mouth and then swallowed, 4 times a day - 400 ml daily. Each period was 5 days, with 2 days break. The exposed to the solutions intact and demineralized parts of the slabs were compared with a varnished intact and varnished demineralized parts. The concentration of F was analysed in the enamel surface layer using the method of J. Weatherall (1973) in all 360 samples. The uptake of F in enamel was found to be greater when F-milk is swallowed, compared with rinsed and with swallowed F-water for sound as well as for demineralized enamel.
