Effect of pH of amine fluoride containing toothpastes on enamel remineralization in vitro.

Background: One of the important factors of the demineralization and remineralization equilibrium of enamel is the pH of the surrounding solutions. Effort has been laid in the formulation of different fluoride compounds and the fluoride content in toothpastes but much less is known about the influence of the pH of the toothpastes on their effectiveness. It was therefore the aim of this study to investigate the influence of different pH levels on enamel remineralization in an in vitro experiment using polarization light microscopy and EDX quantitative element analysis.

Effect of fluoride toothpastes on enamel demineralization.

Background: It was the aim of this study to investigate the effect of four different toothpastes with differing fluoride compounds on enamel remineralization.

Methods: A 3 x 3 mm window on the enamel surface of 90 human premolars was demineralized in a hydroxyethylcellulose solution at pH 4.8.

[Evaluation of clinical effects of amine fluoride/stannous fluoride containing toothpaste and mouthrinse].

The aim of the study was to evaluate the effects of amine fluoride (AmF)/stannous fluoride (SnF2) containing toothpaste and mouthrinse on gingival health of young adults. Altogether 42 persons participated in the study (mean age: 28.3 +/- 7.

Effect of amine fluoride/stannous fluoride toothpaste and mouthrinse on dental plaque accumulation and gingival health.

Objective: The aim was to investigate the influence of amine fluoride (AmF)/stannous fluoride (SnF2) containing toothpaste and mouthrinse on plaque accumulation and gingival health of young adults after 4 weeks use.

Subject And Methods: Forty-two young adults (mean age: 28.33 +/- 7.

Effect of fluoride on cariogenic oral microorganisms (an in vitro study).

The effect of sodium fluoride and sodium monofluorophosphate at concentrations of 1, 5, 10, 50, 100 and 1000 mg/l in phosphate buffer (pH 6.5) as well as in UHT milk were studied on cultures and suspensions of Streptococcus mutans, Lactobacillus acidophilus and Candida albicans. Using serial tenfold dilutions up to 10(-7) of 24-48 hour cultures, a subsequent 0, 60 and 120 min incubation caused no decrease in the number of CFUs.
