“…Development of different types of biopsy techniques enabled further information of enamel fluoride in populations to be detailed. Even though the use of these techniques fostered much work on the pre-and post-eruptive acquisition of enamel fluoride, it was also the application of biopsy techniques which disclosed that there was no simple relation between enamel fluoride and caries experience (Poulsen and Larsen, 1975;DePaola et ai., 1975;Keene et ai., 1975;Bischoff et al, 1976;Shern et al, 1977;Richards et ai., 1977;Bruun et al, 1983;Retief et al, 1987). Furthermore, primary teeth from communities with around 1 ppm F in the drinking water have lower levels of enamel fluoride than do permanent teeth from a non-fluoridated area (Mellberg, 1977;Mellberg and Singer, 1977).…”

Recent clinical and laboratory evidence has suggested that systemic fluoride plays a more minor role in caries inhibition than was previously believed. This paper reviews clinical data on water fluoridation, the topical administration of fluorides, and fluoride supplements in the light of more recent understanding of the disease dental caries. Due to reduced functional usage, erupting teeth tend to accumulate plaque which has cariogenic potential. For this reason, the period from tooth emergence to the establishment of interproximal contact and full occlusion is the most critical for caries initiation. Analyses of clinical data indicate that maximum protection against caries is obtained when teeth erupt into an environment with low concentrations of ionic fluoride. The similarity in caries reductions obtained in water fluoridation studies and long-term studies with topically administered fluoride regimens, including fluoride-containing dentifrices, indicates that the pre-eruptive effect of fluoride is of borderline significance relative to the more significant post-eruptive effect. Water fluoridation and topical fluoride programs are thus important measures for the control of caries at the community level. For the individual, topical application of fluoride is seen as an integral part of caries treatment aimed at arresting progressive caries. Fluoride application is thus considered a supportive therapy, in conjunction with cariogenic plaque control. Daily use of fluoridated dentifrices from tooth eruption is more efficacious than daily use of fluoride supplements from birth.

“…The presumed benefit from fluoride's reduction of enamel solubility is based on studies that reported higher concentrations in teeth from fluoridated as against nonfluoridated areas (46)(47)(48)(49)(50), and the in vitro observation that fluorapatite is less soluble than hydroxyapatite when exposed to acids (51)(52)(53). Several recent studies, however, have detected only slight differences in enamel fluoride concentration between fluoridated and nonfluoridated areas (54)(55)(56), and no differences could be detected between groups of Danish children who did or did not take fluoride supplements prior to tooth eruption (57). Earlier, it had been suggested that incorporation of fluoride only into the outermost layers of enamel was sufficient to permit all the enamel to behave as fluorapatite (58).…”

The Pre‐and Posteruptive Effects of Fluoride in the Caries Decline

The widespread availability of fluoride from many sources is accepted as a major reason for the caries decline among children in developed countries. There is still controversy, however, about its principal mode of action. This article reviews the evidence on fluoride's preeruptive and posteruptive effects, and suggests reasons for its continuing role in the caries decline. Early fluoridation studies accepted that fluoride acted preruptively through incorporation into developing enamel; but further research could not explain why fluoride levels were not clearly higher in enamel exposed to fluoride, nor why there were no clear correlations between caries experience and enamel fluoride concentration. Instead, considerable evidence suggests that fluoride acts mainly, though not entirely, through posteruptive remineralization of demineralized enamel. Caries experience has declined in nonfluoridated as well as in fluoridated areas, though DMF scores are still consistently lower in fluoridated areas. Posteruptive remineralization effects are seen from fluoridated drinking water as well as with fluoride from other sources. The continuing caries decline, beyond the level suggested by early fluoridation field trials, can be attributed either to more efficient remineralization or to long-term, intraoral ecological change, or to both.
