The enamel protection by fluoride ion in mouthrinses: study in vitro

Abstract

The fluoride ion administer em humans through different whicles, is one chemical element that to be incorporate in cristal net of enamel, begining essencial of dental health. This question is found at possibility this drug, especially, sodium fluoride - NaF, to step breaking this biologic structure, reducing this mineral's lost satisfactory and, contribute to prevent and control the dental carie. While preventive resource, the fluoride is one pharmaco alternative realized in programs of public health, account his effective significant and the cost low. Directing subsidy in the literatury who attend of sodium fluoride - NaF effective, through mouthwashes, this study had for objective determines, in vitro, the enamel protection fluoride ion in six mouthrinses, utilize how terapeutic resource fluoride application, of concentration low and frequent use, after experience exhibition in pH 6.8, 6.5, 6.0, 5.0 e 4.5 values. The rates of enamel phosphate liberate previously treaty, express en mg/dL/20 min, were determined through of espectrophotometric technique, on changed Gomori and Baginsk method (React Doles and Lab Equipment Ltda). The answers found developed the fluoride protective power in six estimated mouthrinses. The industrial objects Fluoride Herbal Smile Bucal Fresh ( E1) and Fluoride Bucal Plax Mouthrinses (E2), present best answers, whose apology is in concentration of present fluoride ion, otherwise: 228 ppm F- and 227 ppm F-, respectively. The others mouthwashes with concentration of 226 ppm F-, present the same protective power, although present significants statistics differences in comparison the products E1 and E2. This find supposed, probably, to fluoride lower concentration. In front of challenge of dismineralization critical pH - 5.5, the Oral-B Fluoride Bucal Mouthrinses ( E6 = 226 ppm F-) had the performance nearer the mouthwashes E1 and E2, although present trajectory less homogeny in front of others levels pH. It is possible, after this results, affirm that the proved mouthrinses had industrial quality control appropriate.
