Stoichoimetric graphene fluoride monolayers are obtained in a single step by the liquid-phase exfoliation of graphite fluoride with sulfolane. Comparative quantum-mechanical calculations reveal that graphene fluoride is the most thermodynamically stable of five studied hypothetical graphene derivatives; graphane, graphene fluoride, bromide, chloride, and iodide. The graphene fluoride is transfo...

The above two books by dental scientists have been received by this editor for review. The first is intended for use by dentists and dental students, as was the first edition. Many dental researchers have contributed to this updated survey of dental uses of fluoride. What is remarkable about Fluoride in Dentistry (2nd Edition), especially to anyone concerned with a more interdisciplinary approa...

There is no topically applicable low concentration fluoride delivery device available for caries prevention. This study was aimed to assess the use of a low concentration (1450 ppm) fluoride strip as an effective fluoride delivery system against enamel demineralization. The enamel surface composition and calcium-deficient hydroxyapatite or toothpaste treatments were investigated using X-ray pho...

OBJECTIVES The purpose of this study was to assess the effect of single and combined applications of fluoride on the amount of fluoride release, and the remineralization and physical properties of enamel. MATERIALS AND METHODS Each of four fluoride varnish and gel products (Fluor Protector, FP, Ivoclar Vivadent; Tooth Mousse Plus, TM, GC; 60 Second Gel, A, Germiphene; CavityShield, CS, 3M ESP...

This single-blind, randomized, crossover study aimed at assessing the long-term fluoride concentrations in saliva and in dental biofilm after different home-use fluoride treatments. The study volunteers (n = 38) were residents of an area with fluoridated drinking water. They were administered four treatments, each of which lasted for one week: twice-daily placebo dentifrice, twice-daily fluorid...

A review of evidence-based literature indicates incomplete evidence for the efficacy of most measures currently used for caries prevention, with the exception of fluoride varnishes and the use of fluoride-based interventions for patients with hyposalivation. Not all fluoride agents and treatments are equal. Different fluoride compounds, different vehicles, and vastly different concentrations ha...

Human toxicity NaF and ionic fluoride, later only fluoride (1 mg of NaF corresponds to 0.45 mg of fluoride, also called “fluor”) are toxic for humans at the higher doses; gastrointestinal symptoms have occurred following fluoride ingestion from 3 to 5 mg/kg of body weight. The lethal doses of NaF in adults range from 70 to 140 mg/kg, which corresponds to 31.5-63 mg fluoride/kg of body weight [2...

THE caries inhibitory effect of fluoride is well documented (Brudevold et a], 1967; Horowitz and Heifetz, 1970). •As the initial site of the caries lesion Occurs on the surface of the tooth at the plaque/tooth interface, the fluoride con­ centration in the surface layers of enamel is important in combating the carious process (Isaac et al, 1958; Naylor, 1969). The fluoride in the enamel is deri...

Fluoride, a non-essential element, can enter water resources through several natural processes and human activities. The benefits and risks of fluoride depend on the concentration of this anion on drinking waters. In the present study, the performances of graphene and graphene oxide nanoparticles were investigated for the removal of fluoride from aqueous solution. In the present resea...
