Alkali-soluble fluoride deposition on enamel after professional application of topical fluoride in vitro

Abstract

Since the efficacy of topical fluoride products is related to the fluoride (F) availability and its reactivity with enamel, this study was conducted. The F concentration of the following materials was verified: I- acidulated phosphate fluoride (APF) gel (1.23% F), II- APF foam (1.23% F) and III- Varnish (2.26% F). Forty blocks of bovine enamel were divided into 4 groups and treated according to the materials described, being one of them used as control. Loosely bound fluoride (''CaF2'') was determined on enamel after extraction with 1.0M KOH and analyzed by ion-selective electrode. Total F concentration found in gel was 12,642, in foam 12,755 and in varnish 23,183 mg F/g. All products formed statistically higher amounts of ''CaF2'' on enamel compared to the control group (p < 0.05), but the difference between them was not significant (p > 0.05). Thus, ''CaF2'' formation was not proportional to the total F content in the products, suggesting that the pH and the vehicle used are more important.

Effects of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and fluoride on the microhardness of enamel treated with a bleaching agent: ex vivo

“…37 Aynı şekilde pek çok farklı formda (vernik, gargara, macun, solüsyon) florid preparatı çürük önleme amacıyla yaygın olarak kullanılmak-tadır. 38 Bu çalışmada profesyonel olarak uygulanabildiği gibi hasta tarafından da uygulanabilen CPP-ACP patı, asidik yapısı nedeniyle, daha kısa süre uygulanmalarına ve daha az florid içermelerine karşın verniklere eşdeğer miktarda kalsiyum florid (CaF 2 ) oluşturabilen 39 ve sadece profesyonel olarak uygulanabilen APF jeli ile karşılaştırıldı. Bu çalışmanın sınırları dahilinde remineralize edici ajanlar arasında mine mikrosertliği yönün-den farklılık bulunmadı.…”

In vivo evaluation of therapeutic potential of fluoride varnishes

“…It is likely that the positive effect of the fluoride varnishes was assisted by the improvement in oral hygiene on the part of the participants. Indeed, previous studies state that one cannot dissociate the effect of fluoride varnishes from the effect of proper brushing (8,17,18).…”

“…The following clinical sequence was obeyed in both groups: 1) supervised brushing; 2) drying with gauze; 3) application of fluoride varnish on active white spots with the aid of a brush (FGM, Joinvile, Brazil); 4) five-minute wait for the evaporation of the solvent; 5) removal of excess with cotton ball; and 6) instructions to not brush the teeth and to use a diet of liquids or pasty foods for 12 hours following the application of the product. These clinical procedures were performed once a week for four weeks (16,17). On the fifth week, the white spots were evaluated with regard to dimension and activity.…”

The effect of acidulated phosphate fluoride application on dental enamel surfaces hardness

“…Topical fluoride application is recommended for the children after permanent dental eruption and the patients with high caries risk. 7 Topical fluoride application which is done to the children with dental permanent in non-fluoride area for six months reduce caries risks at permanent teeth for 26%. 8 There are several agents used as topical application, one of them is acidulated phosphate fluoride (APF).…”
