recognised that the decline in the prevalence of
dental caries recorded in most industrialised
countries over the past 30 years can be attributed
mainly to the widespread use of toothpaste that contain fluoride.
Investigations into the effectiveness of adding fluoride to toothpaste have
been carried out since 1945 and cover a wide range of active ingredients in
various abrasive formulations. Fluoride compounds and their combinations which
have been tested for the control of dental decay include sodium fluoride,
stannous fluoride, sodium monofluorophosphate and amine fluoride. The most
widely used fluoride compounds in the Republic of Ireland are sodium fluoride
and sodium monofluorophosphate.
