“…Hence, these re sults are in agreement with the findings of Hagan and Bawden [1985] who applied full-and half-strength acidulated phosphate fluoride gel in ll-to 15-year-old children. The results of Seppa et al [1994] in 12-to 14-year-old children showed a similar caries-preventive effect of sodium fluoride varnish (Duraphat) containing either 2.3% or 1.1% F. Fur thermore, the lowering of the fluoride content of a varnish (Duraphat) from 2.3 to 1.8% (an experimental sodium fluo ride varnish) did not adversely affect the caries incidence in the study performed by Haugejorden and Nord [1991], while even lower concentrations have inhibited enamel dis solution and promoted remineralization in vitro [ten Cate, 1990] or in vivo [Goorhuis and Purdel-Lewis, 1986], In the present study, only the 0.25% amine fluoride solution was less effective than higher concentrations (0.5 and 1% F).…”

A double-blind 3-year clinical trial was conducted in a nonfluoridated water community in which 354 schoolchildren aged 9–10 years were assigned randomly to three groups (A, B and C) and subjected to a treatment with 1 of 3 different concentrations of amine fluoride solution every 2 months. Clinical examinations were conducted at baseline and after 1, 2, and 3 years. For group A (positive control) receiving topical applications of amine fluoride solution (1%), the 3-year DMFT and DMFS increments were 4.0+ (SD) 2.7 and 8.5 ± 5.6, respectively. For group B (0.5% F), the DMFT and DMFS increments were 4.4 ± 3.0 and 8.4 ± 5.7, respectively; these differences being statistically not significant. The mean caries increments in group C (0.25% F) were 5.1 ± 2.9 for DMFT and 10.0+5.5 for DMFS. The differences in incremental caries scores between group C and groups A or B were statistically significant (p < 0.05). Thus, the amine fluoride solution, in which the fluoride content was reduced by half, provided similar caries reductions in schoolchildren as did a standard amine fluoride solution with 1.0% F.

“…Anticaries efficacy of low-fluoride professional preparations (gel, varnishes) has also been shown in some other clinical studies [Hagan et al, 1985;Haugejorden and Nord, 1991;Seppä et al, 1994]. However, in individuals with poor oral hygiene and severe plaque accumulation, fluoride agents may have a limited cariostatic potential and no dose-response relationship could be observed.…”

The aim of this in vitro study was to examine whether the concentration of amine fluoride solution influences the uptake of fluoride by enamel after topical treatment. Four slabs were prepared from each of 31 impacted third molars and selected at random so that one slab from each tooth was present in each group. One group of slabs served as an untreated control (D). The slabs of the other three groups were shaken for 3 min in an amine fluoride solution on 3 successive days: group A (1% F), group B (0.5% F) and group C (0.25% F). The amounts of KOH-soluble fluoride produced with 1 and 0.5% amine fluoride solution did not differ significantly and were superior to 0.25% amine fluoride solution. A statistically significant increase in structurally bound fluoride was observed in groups A, B and C compared with control group D. The difference in the amounts of structurally bound fluoride was significant only between 1 and 0.25% F concentrations. These data suggest that the fluoride content in an amine fluoride solution (1%) can be decreased by half without reducing its ability to form alkali-soluble or structurally bound fluoride. The results of this study are consistent with those of previous clinical studies.

The role of fluoride (F) dentifrices in caries decline was investigated by assessing the effect of variation in their use on caries scores among teenagers. The material comprised 211 subjects aged about 11 years at base line and 18 years at the last examination. Pairs of posterior bitewing radiographs were assessed by one examiner. Information concerning dental health behavior was collected by questionnaire and about treatment received from dental records. A reversal of the traditional DFS gender difference occurred during teenage years. Multivariate regression analyses showed an inverse relationship between variation in F dentifrice use and current decay (D1S) at age 18 years (P < 0.04) and with caries incidence per year (D1FS) during the whole observation period (P < 0.02). Total explained variance in 6-year deltaD1FS scores was 29.8%, of which variation in toothbrushing behavior contributed 1.8 percentage points. While confirming the multifactorial nature of dental caries, these results also provided quantitative evidence for the role of variation in F dentifrice use in caries incidence and decline.
