... have only involved measurement of F in 1 or 2 types of sample. The present study investigated the relationships of F concentrations in biomarkers of F exposure; including plasma, saliva, hair, finger- and toenails, and daily urinary F excretion (UFE) with the total daily F intake (TDFI) of adults. TDFI...

... (UFE) and fluoride concentrations in plasma, fasting whole saliva, hair, and nails (toenails/fingernails) were evaluated and related to total fluoride exposure. TDFI, UFE, and fluoride concentrations of biomarkers were statistically significantly higher in the high-fluoride area than in the low...

Eckert The aim was to compare potential methods for fluoride analysis in microlitre-volume plasma samples containing nano-gram amounts of fluoride. Methods: A group of 4 laboratories...

... afterwards; and (D) ingestion of the toothpaste as a slurry with 100 ml of de-ionized water. Blood samples were collected before and frequently for 6 h after each experiment and analyzed for F content. The area under the plasma F concentration vs. time curves (AUC) was calculated and the degree of F...

... ranging between 0.4 and 0.6 ml/min, where the fluoride concentration ranged from 4.7 to 19.2 μmol/l. In a separate study, the fluoride concentration in plasma in 4 subjects was studied for 24 h following repeated use of 0.5 mg fluoride as two pieces of the gum 10 times a day. The plasma levels found...

...J. Ekstrand The plasma fluoride concentration in 15 subjects living in three different districts with 9.6, 1.2 and 0.25 ppm fluoride in the drinking water, was followed over 36 h. In the 9.6-ppm-fluoride area there was a wide fluctuation in the plasma fluoride concentration during the day compared...

...Jan Ekstrand; Mats Ehrnebo The bioavailability of fluoride (F) from NaF and Na 2 PO 3 F dentifrices was studied in detail in young volunteers. The method used was based on a comparison of plasma and urinary data obtained following intravenous administration of a single 3-mg dose F and ingestion...

... doses of fluoride (doses used in caries prevention) had any effect on the cyclic AMP level in plasma. 21 male volunteers participated in the experiment. One group (n = 7) received 0.05 mg F - /kg BW, one group (n = 7) 0.1 mg F - /kg BW, and one control group (n = 7) 0.1 mg Cl - /kg BW. Blood samples...

.... They consisted of 500 ml of a 10 ppm F water solution, 500 ml milk containing 10 ppm F and 500 ml of a baby formula prepared with a 10 ppm F solution. Plasma F and urinary F levels were subsequently monitored for 15 h. Pharmacokinetic analysis of the data was performed and F bioavailability calculated...

...J. Ekstrand; G. Koch; L.E. Lindgren; L.G. Petersson Plasma fluoride (F) concentration and urinary F excretion were studied in 8 children and 5 adults following topical application of three different types of F gel, (Luride® 1.23% F, Gel II® 1.23% F, Fluor gel 0.1% F). The amount of F gel applied...
