Tooth-fluoride interactions in relation to dental erosion
Alix Young Vik and Lene Hystad Hove, from the Institute of Clinical Dentistry, Faculty of Dentistry, at UiO will present some of their reseach about the interaction between fluorides and the tooth enamel.

Dental caries or tooth decay, which is caused by bacterial acids, has declined significantly since fluoride became widely available in toothpaste. However the problem of tooth damage caused by dietary acids or reflux of stomach acids, namely dental erosion, seems to be an increasing problem in many societies. Standard fluoride toothpaste does not seem sufficient to prevent dental erosion in risk individuals, and this finding has prompted more research into better ways of strengthening tooth surfaces against acidic insults. Our in vitro, in situ, and experimental in vivo studies have examined the protective effects of different types of fluorides using different clinical models and measurement techniques.
