[The use of fluorides in dentistry in the year 2003]

During the 20th century the entire Western world has been plagued by a tremendous increase of carious lesions in the dentition of children and adults. Near the end of that century a definite decrease in the number of carious lesions was noticed. That improvement in dental health is mainly attributed to an increased presence of fluorides in the oral cavity. Fluorides can be administrated systemically or locally. Recent findings clearly suggest that a local administration is the preferred option. Correctly applicated the local use of fluorides provides a favourable and positive effect during demineralization and remineralisation processes under carious attack. Although fluorides are not the only measure in caries prevention it is widely believed that they have largely contributed to an improvement of oral health, the relief of dental pain and the safeguarding of financial means during the last twenty five years.
