“…With the purpose of minimizing this problem, many agents for bonding and cementing have been produced with fluoride, such as glass ionomer. 29 Nevertheless, even these fluoride-rich cements can be dissolved by oral fluids if the bands are not well adapted, creating an excellent cariogenic locus wherein the patient cannot clean with brushing or flossing.…”

Introduction: Titanium tetrafluoride (TiF4) is a fluoride compound that, when is applied over enamel, promotes a protection against demineralization through a titanium dioxide (TiO2) acid-resistant coat. Objectives: This study sought to verify the hypothesis that a single application of 4% TiF4 increases the resistance of enamel to dental demineralization in orthodontic patients. Materials and Methods: This controlled clinical trial followed CONSORT guidelines and investigated the prevention of enamel demineralization, fluoride retention, and the presence of a Ti layer after TiF4 application on banded teeth exposed to clinical cariogenic biofilm. Forty premolars were divided into a control group (CG; n = 20) and a test group (TG; n = 20). Teeth from both groups received prophylaxis and orthodontic bands with a cariogenic locus. In the TG, all teeth additionally underwent aqueous 4% TiF4 solution application after prophylaxis before being banded. After one month, teeth from both groups were extracted and prepared to assess the microhardness, fluoride retention, and evaluation of the Ti coating over the enamel surface. All data were analyzed with a paired Student’s t-test (p<0.05). Results: Enamel microhardness and fluoride uptake were higher in TG than in CG, while the Ti layer could be seen over TG teeth that received TiF4 application. Conclusion: Under clinical circumstances, the 4% aqueous TiF4 solution was effective in preventing enamel mineral loss through increasing the enamel resistance to dental demineralization, enhancing its microhardness and fluoride uptake, and forming a Ti coat.

“…Since the introduction of orthodontic bonding systems, some new materials have been developed to improve clinical results. 1 Many studies focused on adhesive bond strength 2 and properties such as: stiffness, 3 color stability, 4 fluoride release, 5 inhibition of microbiological growth, 5 cytotoxicity, 6 amongst others. The goals of new adhesives are oral health maintenance, patient and professional satisfaction, and enhancing treatment.…”

Introdução: O excesso de material de colagem que permanece ao redor dos bráquetes impacta negativamente a saúde bucal dos pacientes ortodônticos. Objetivo: Avaliar a influência dos sistemas de colagem ortodônticos na remoção de excesso de adesivo ao redor de bráquetes. Métodos: Baseado em suas características, quatro sistemas de colagem ortodônticos foram selecionados: adesivo fotopolimerizável (G1 -Transbond TM XT); adesivo fotopolimerizável com pigmentação rosa (G2 -Transbond TM Plus Color Change); cimento de ionômero de vidro reforçado com resina (G3 -FujiOrtho TM LC); e adesivo autopolimerizável (G4 -Concise TM ). Para cada grupo (n=10), um único operador posicionou os bráquetes em dentes bovinos (n=40) e utilizou uma sonda exploradora para remoção visual do excesso de material de colagem. Após a polimerização / tempo de cura, as amostras foram levadas ao estereomicroscópio e o software Axio Vision 4,4 foi utilizado para mensurar a área de excesso de adesivo remanescente ao redor de cada bráquete. Os dados quantitativos obtidos foram analisados pelos testes de Kruskal-Wallis e post-hoc de Dunn em significância de = 0,05. Resultados: O cimento de ionômero de vidro reforçado por resina (G3) apresentou a maior área de remanescente de excesso. Não houve diferença estatisticamente significativa entre os demais grupos (G1, G2 e G4), independente da pigmentação ou do método de polimerização. Conclusão: O uso de cimento de ionômero de vidro reforçado por resina resulta em maior área de excesso remanescente, o que pode impactar negativamente a saúde bucal. A pigmentação e o método de polimerização não influenciaram no excesso de material remanescente.

The influence of protective varnish on the integrity of orthodontic cements

Abstract: Varnish application is necessary to preserve the cement and avoid enamel decalcification. Glass-ionomer cements should be protected in order to fully keep their properties, thus contributing to dental health during orthodontic treatment.
