This study assessed fluoride (F) and sodium trimetaphosphate (TMP) release into artificial saliva from varnishes containing 0%, 2.5%, and 5% NaF, supplemented or not with 5% TMP. The varnishes were applied on polyester sheets (n = 8/group), and F and TMP released into artificial saliva were measured for up to 24 hours. The amount of F and TMP released were directly related to NaF and TMP concen...

Fluoride release from fluoride varnishes under acidic conditions.

OBJECTIVE The aim was to investigate the in vitro fluoride release from fluoride varnishes under acidic conditions. STUDY DESIGN Poly(methyl methacrylate) blocks (Perspex, n=3 per group) were painted with 80 ± 5 mg fluoride varnish (n=10) and placed into artificial saliva for 30 min. Then, blocks were placed into either 1% citric acid (pH 2.27) or 0.3% citric acid (pH 3.75) solutions (n=3 per...

Fluoride varnishes with calcium glycerophosphate: fluoride release and effect on in vitro enamel demineralization.

The aims of this study were (1) to assess the amount of fluoride (F) released from varnishes containing calcium glycerophosphate (CaGP) and (2) to assess the effect of the experimental varnishes on in vitro demineralization. Six test groups using 5 varnishes: base varnish (no active ingredients); Duraphat® (2.26% NaF); Duofluorid® (5.63% NaF/CaF2); experimental varnish 1 (1% CaGP/5.63% NaF/CaF2...

Fluoride release from three glass ionomers after exposure to sodium fluoride and acidulated phosphate fluoride gels

BACKGROUND Glass ionomer (GI) restorations exposed to fluoride have the ability to slowly release fluoride. Therefore, the aim of this study was to investigate fluoride release from three GIs before and after exposure to sodium fluoride (NaF) and acidulated phosphate fluoride (APF). MATERIALS AND METHODS Fifteen disc-shaped samples (6 mm in diameter and 2 mm in thickness) from three GIs (Fuji...

Fluoride varnishes in caries prevention.

The first fluoride varnishes were developed during the 1960s (Duraphat) sodium fluoride varnish) and 1970s (Fluor Protector) silane fluoride varnish) to prolong the contact time between fluoride and enamel. Fluoride varnishes adhere to enamel, and calcium fluoride formed after application acts as a long-term reservoir of fluoride. Currently Duraphat varnish is the most widely used topical fluor...
