Clinical study of an amine fluoride gel and acidulated phosphate fluoride gel.

This study compared caries inhibition in children by an amine fluoride and an acidulated phosphate fluoride when administered in a topically applied gel. In addition, the effects of applying amine fluoride daily and weekly were compared. Four hundred and sixty-eight children, ages 6 to 13, were randomly assigned to one of five treatment groups and received a total of five, 5-minute treatments. The treatment and interval between each of the five treatments were as follows:(A)acidulated phosphate fluoride daily, (B) amine fluoride daily, (C) amine fluoride weekly, (D) placebo daily, and (E) placebo weekly. When the children were examined for total Decayed, Missing, and Filled Surfaces (DMFS) increments 2 years later, no significant differences were observed. However, when the data were examined for effects of DMFS for specific tooth surface, significant restriction (61%) of occlusal increment was shown in the group which was treated with amine fluoride daily for 5 consecutive days as compared with the control group.

Effect of fluoridated dentifrice and acidulated phosphate fluoride application on early artificial carious lesions.

PURPOSE: To evaluate the effect of a combination of fluoride dentifrice and acidulated phosphate fluoride (APF) on enamel with incipient caries lesions. MATERIALS AND METHODS: Bovine dental enamel blocks with artificial caries lesions were divided into four treatment groups and submitted to a pH-cycling model: (1) Placebo non-fluoridated dentifrice (PD); (2) Fluoridated dentifrice (FD), 1,100 ppm F; (3) APF (12,300 ppm F, pH 3.5) + PD; 4) APF+FD. APF was applied to enamel blocks of groups APF+PD and APF+FD before the pH-cycling regimen and all of them were exposed to dentifrice during the cycling. RESULTS: The results showed that 61-81% of the fluoride previously deposited in enamel by APF was released to the media during the pH-cycling. The final concentration of fluoride in enamel in the group APF+PD was lower than that before the cycling (P < 0.05), but in the group APF+FD the reduction was not significant (P> 0.05). FD treatment was significantly more efficient than PD in rehardening the enamel surface and increasing the hardness of the caries lesions. APF+PD treatment was not more efficient than PD in increasing enamel hardness and an additive effect of APF+FD was not observed.

Fluoride varnish versus acidulated phosphate fluoride gel: a 3-year clinical trial.

The aim of this trial was to compare the caries-preventive effect of sodium fluoride varnish and acidulated phosphate fluoride (APF) gel. A total of 254 children aged 12-13 years with high past caries experience were randomly divided into two groups. The participants received semi-annual applications of either fluoride varnish or APF gel for 3 years. During the study, the mean (+/- SD) total DMFS increments of the varnish and gel groups were 6.8 +/- 5.6 and 7.7 +/- 6.4, respectively, when initial caries was included, and 3.1 +/- 3.7 and 3.6 +/- 4.6 when initial caries was excluded. The difference was most evident on the approximal surfaces (varnish: 1.4 +/- 2.4; gel: 1.9 +/- 3.1). However, this difference was not statistically significant. Although larger studies are needed for firm conclusions about the comparative effect of the two fluoride measures, the results suggest that fluoride varnish is as effective as fluoride gel at least in preventing approximal caries. Taking into account the shorter treatment time, using fluoride varnish for professional applications seems justified.

In vitro evaluation of fluoride uptake with application of acidulated phosphate fluoride to interproximal enamel of primary teeth using dental floss.

As a result of application of acidulated phosphate gel with a dental floss on adjoining surfaces of primary molars it has been established that there has been significant fluoride intake as compared with the control group. It has been concluded that it is an efficient method of increasing fluoride content of the primary teeth.

The antimicrobial effect of fluorides (acidulated phosphate, sodium and stannous) on Actinomyces viscosus.

The effect of three commercially prepared fluoride compounds (acidulated phosphate fluoride 1.23% F-, stannous fluoride 0.4%, and sodium fluoride 0.05%) diluted to various concentrations with brain heart infusion broth, on the growth of five strains of Actinomyces viscosus following 1 and 24 hours' exposure to the fluorides was studied. Results demonstrated that SnF2 was the most effective growth inhibitor of the organisms at 500 ppm F- after 1 hour and at 100 ppm F- after 24 hours' exposure. APF and NaF were not effective within a 1 hour exposure period, but did suppress growth of the organisms at 200 ppm in the cultures exposed for 24 hours.

Comparison of acidulated phosphate fluoride gel and hydrofluoric acid etchants for porcelain-composite repair.

Hydrofluoric acid etches porcelain to produce a porous surface visible under scanning electron microscopy when compared to an acidulated phosphate fluoride gel. Some investigators have suggested the greater porosity of the hydrofluoric acid etch produces a greater composite-to-porcelain bond. This investigation tested that assumption with two common fluoride etchants. The etched surfaces were first viewed under scanning electron microscopy to ensure that a characteristic etch was achieved. Both etchants yielded bond strengths that produced cohesive failure of all samples. This suggested that the intraoral use of hydrofluoric acid is no more effective than the less dangerous acidulated phosphate fluoride gel.
