Efeito de vernizes fluoretados suplementados com nanopartículas de trimetafosfato de sódio sobre o desgaste dental erosivo in vitro e in situ

O presente estudo avaliou o efeito de vernizes fluoretados suplementados com nanopartículas de Trimetafosfato de Sódio (TMP) sobre o desgaste erosivo do esmalte dental bovino, em protocolos in vitro e in situ. Para a 1ª fase, blocos de esmalte dental bovino (n=100) foram selecionados por meio de durez...

Comparación de tres agentes remineralizantes utilizados en lesiones de manchas blancas en premolares medidos con fluorescencia láser: un estudio in vitro

Rev. cient. odontol; 7 (1), 2019
Objetivo: Evaluar la remineralización de lesiones de manchas blancas en el esmalte de premolares humanos a través de la fluorescencia láser utilizando el barniz de flúor al 5% (Duraphat®), la nanohidroxiapatita (Nano P®), y la combinación de ambos agentes, a los 3...

Effect of a resin-modified glass-ionomer with calcium on enamel demineralization inhibition: an in vitro study

Abstract We assessed the effect of a new coating material based on resin-modified glass-ionomer with calcium (Ca) in inhibiting the demineralization of underlying and adjacent areas surrounding caries-like lesions in enamel. The measures used were surface hardness (SH) and cross-sectional hardness (CSH)....

Effect of fluoride application during radiotherapy on enamel demineralization

J. appl. oral sci; 27 (), 2019
Abstract Radiation-related caries are one the most undesired reactions manifested during or after head and neck radiotherapy. Fluoride application is an important strategy to reduce demineralization and enhance remineralizaton. Objective: To evaluate the effect of the topical application of fluoride dur...

Remineralizing effect of commercial fluoride varnishes on artificial enamel lesions

Abstract: The aim of this study was to evaluate soluble and insoluble fluoride concentrations in commercial varnishes, and their remineralization effect on artificial caries enamel lesions using surface and cross-sectional microhardness evaluations. Forty bovine enamel blocks were separated into four gro...

Effect of titanium tetrafluoride varnish on fibroblasts (NIH/3T3): viability assay, morphological analysis and cell signals for apoptotic pathways

Current knowledge supports the application of TiF4 varnish to protect against tooth caries and erosion; however, it is indispensable to know its cytotoxic potential and the mechanism involved on it before applying in patients. Therefore, this study aimed to evaluate 1) The cytotoxic effect of titanium te...

Fluoride Varnishes against Dental Erosion Caused by Soft Drink Combined with Pediatric Liquid Medicine

Braz. dent. j; 28 (4), 2017
Abstract The present study evaluated the effect of NaF and CPP-ACP/NaF varnishes to reduce erosion produced by soft drink (SD) combined or not with pediatric liquid medicine. Enamel specimens were pre-treated with fluoride varnish, according to the following groups: NaF varnish (Duraphat®) or CPP-ACP/Na...

Influence of resin-modified glass ionomer and topical fluoride on levels of Streptococcus mutans in saliva and biofilm adjacent to metallic brackets

J. appl. oral sci; 25 (2), 2017
Abstract Decalcification of enamel during fixed orthodontic appliance treatment remains a problem. White spot lesions are observed in nearly 50% of patients undergoing orthodontic treatment. The use of fluoride-containing orthodontic materials has shown inconclusive results on their ability to reduce dec...

Evaluación clínica de barniz de flúor en el manejo de la hipersensibilidad dentinaria

La Hipersensibilidad Dentinaria (HD) se define como un corto y fuerte dolor generado por la exposición de dentina, que surge de un estímulo químico, térmico, táctil u osmótico, el cual no puede catalogarse como una patología dental propiamente tal. La teoría hidrodinámica de Brännström es la m...

Desenvolvimento de uma formulação de verniz fluoretado suplementado com trimetafosfato de sódio: ação sobre a cárie e erosão dentária em protocolos in vitro, in situ e in vivo

O presente estudo avaliou o efeito de vernizes fluoretados contendo trimetafosfato de sódio (TMP) sobre a desmineralização, remineralização e desgaste erosivo do esmalte dentário, utilizando protocolos in vitro e in situ, bem como sobre o desenvolvimento de lesões de cárie em criançase adolescen...
