Despite the latest advances in orthodontic treatment, white spot lesions remain a common side effect of fixed appliance therapy. An effective treatment for prevention is use fluoride-containing products. The aim present vitro study was to check durability tested products their fluoride release into surrounding solution. Three varnishes (Protecto CaF2 Nano one-step seal, Bifluorid 12 single dose...

The nucleophilic reactivity of fluoride ion is altered in the presence of hydrogen-bond donors, including alcohols. Relatively little is known about the coordination involved; to rectify this, the X-ray structures of fourteen novel fluoride–alcohol complexes with tetrabutylammonium as the counterion have been determined. The coordination number varies from two to four depending on the steric bu...

The ability of uv light-cured fissure sealants to release fluoride ion from different concentrations of sodium fluoride (NaF), over a 3-week period was studied. Two hundred samples of sealant were prepared in which 1 group contained no fluoride (control) and 4 others contained NaF at 0.05, 0.2, 0.5, and 2% concentrations, respectively. The fluoride ion released by each sample after 1 day, 3 day...

Dental caries still continues to be a problem for majority of individuals and it can be a serious problem for medically compromised, developmentally disabled and elderly individuals. Water fluoridation, systemic and topical fluorides have been used for many years to supply supplemental fluoride to combat dental caries. The latest fluoride research is investigating the use of slow release device...

Chronic fluoride over-exposure during pre-eruptive enamel development can cause dental fluorosis. Severe dental fluorosis is characterized by porous, soft enamel that is vulnerable to erosion and decay. The prevalence of dental fluorosis among the population in the USA, India and China is increasing. Other than avoiding excessive intake, treatments to prevent dental fluorosis remain unknown. We...

Objective: To compare the release of fluoride into unstimulated wholesaliva in vivo after the application of three different 5% NaF varnishes:Enamel Pro, Vanish, and Duraphat.Experimental Methods: Following IRB approval, 15 subjects wererecruited and consented based upon the inclusion/exclusion criteria of thestudy. A four-treatment randomized cross over study design wit...

BACKGROUND The incorporation of fluoride into sealants has been viewed as a viable way to prevent pit-and-fissure caries by potential inhibition of demineralization through the release of fluoride to enamel. The authors conducted a study to examine the effect of a recently introduced fluoride-releasing sealant (ProSeal, Reliance Orthodontic Products, Itasca, Ill.) on enamel demineralization in ...
