[Fluoride in children saliva with its natural low intake in cases of fluoridated salt or water consumption].
Fluoride content dynamics in whole saliva in 3 groups of 5-6 year old children before and after meal. All children lived in the region with lov F-0,2 ppm in water, used fluoridated toothpaste and went to kindergartens. Children from group A (n=10) did not have other sources of F, group B children (n=10) drink one glass a day of F-water (1 ppm), participants from group C (n=11) eat F-salt 250+/-100 ppm. The F in saliva samples gathered prior to and following meal was determined. Before the meal children saliva in group A contains 0,058 ppm F, in group B - 0,078 ppm F, in group C - 0,074 ppm F. Saliva of group A children shows the increase of F after the meal (0,067 ppm), F decreases lower the starting point after the 5th minute (0,056 ppm) and restores to normal by minute 40. Group B showed the decrease of F right after the meal, lasting to minute 20 (0,060 ppm), than a small increase followed (0,063 ppm), and finally the restoration to normal by minute 50. In group C immediate raise of F (0,085 ppm) was noticed, by minute 10 - some decline (0,076 ppm), from minute 20 F rises to level 0,090 ppm, after that it is decreasing slowly, but by minute 60 remains higher tan the starting point (0, 076 ppm). Thus, F-salt use allows to raise a basic level of F, and also to positively change F dynamics in oral fluid during the risk period (after the meal intake).
