Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Fluoride concentration in biofilm fluid
Tidsramme: 30min
|
Remants of dental plaque (biofilm) will be collected 30 min after brushing with the toothpastes, the fluid will be separated from the solids by centrifugation and the fluoride concentration in the biofilm fluid will be determined by a fluoride electrode adapted for microanalysis.
|
30min
|
|
Urinary fluoride excretion
Tidsramme: 8h
|
Urine will be collected at two time-points, either before the use of the toothpaste or at the last day of use, in each experimental phase.
Fluoride concentration was determined by an inverted ion-specific fluoride electrode and fluoride excretion will be measured by fluoride/cratinine ratio (mg F/mg creatinine).

Tidsramme |
|---|---|---|
|
Fluoride concentration in biofilm solid
Tidsramme: 30min
|
Remants of dental plaque (biofilm) will be collected 30 min after brushing with the toothpastes, the fluid will be separated from the solids by centrifugation and the fluoride concentration in the biofilm solids will be determined after acid extraction using a fluoride electrode adapted for microanalysis.
|
30min
|
|
Fluoride concentration in saliva
Tidsramme: 30min
|
Non-stimulated saliva will be collected at 0 (immediately before toothbrushing), 7, 15 and 30 min after toothbrushing.
Fluoride concentration in saliva will be determined by a ion-specific fluoride electrode, adapted for microanalysis.
|
30min

|
Amount of toothpaste ingested
Tidsramme: January 2013 to July 2013
|
Determination of amount of toothpaste ingested after one simulated brushing.
