Application Of Fluoride Solution Research Articles

Efeito de Três Soluções Tópicas de Flúor no Nível de Flúor do Biofilme Dentário

Objective: To examine process inside plaque after application of three topical fluoride solutions: 1% TiF4, 1% NaF and Aminfluorid solution. Efficiency of three of these was estimated through concentrations of fluoride ions. Methods: Fluoride ions concentrations were measured and demonstrated as potential of fluoride electrode. 60 adult volunteers, divided in three groups (20 volunteers for each group, one agent per one group) have participated in the research. Subjects refrained of oral hygiene for 48 hours before the experiment. Plaque samples were taken before the application of fluoride solutions, and again after 5, 30, 60 and 120 minutes following the treatment. Results: Fluoride concentrations in plaque were not significantly different for three tested solutions. Conclusion: There isn’t clinically significant difference in efficacy of three used topical fluoride agents, despite their pH values differences. Only one statistically significant difference appeared after 60 minutes between sodium fluoride and titanium tetra fluoride, but it disappeared after 120 minutes.

An Evaluation of the Use of Professional (Operator-applied) Topical Fluorides

Application of fluoride solutions, gels, varnishes, and prophylaxis pastes is reviewed as well as the sequential APF/SnF2 office-rinse method. The most widely-used technique is with 1.23% APF gel (12,300 ppm F) in trays. Clinical results from this method are similar to those achieved with an APF solution of the same fluoride concentration. A professional APF gel/tray application need not be preceded by a prophylaxis, should last four min, and should not be followed by a water rinse for 30 min. Fluoride varnishes are newer topical fluoride agents, but their relative efficacy, compared with other proven caries-inhibitory methods, remains to be fully determined. In general, fluoride prophylaxis pastes have not been shown to inhibit caries; however, their use is justified by the ability of some to replenish fluoride lost from the abrasive action of the paste on tooth enamel. The sequential office-rinse method has not been tested in randomized clinical trials, and its use cannot be recommended.

Fluoride Therapy for the Control of Dental Caries

F o r c e n t u r i e s research workers have been investigating the cause and methods of control of one of the most prevalent of diseases, dental caries. Even today knowledge of the causes of this disease is limited and methods of control are empirical, many being impractical and of unproved value. During the past decade research studies on the relation of fluoride-bearing waters and other flu­ oride solutions to dental caries have given promise of a new era in caries control. Epidemiologic studies, labora­ tory investigations and clinical trials sug­ gest that the incidence of dental caries can be reduced materially by fluoride therapy. The accumulated evidence to date on the fluorine-dental caries relation sug­ gests three different avenues of attack: ( i ) by adjusting the fluoride concentra­ tion in public water supplies to an op­ timum level; (2) by topical application of fluoride solutions to the erupted tooth surface, and (3) by increasing fluoride ingestion through daily supplements of this element to the diet. This paper discusses briefly some of the scientific evidence supporting these three methods of fluoride therapy.
