“…Bonding materials based on glass ionomer cement (GIC) have been commercially available for a long period of time 4 and these materials possess many important properties, such as biocompatibility with the enamel and dentin, and cariostatic effect. However, conventional GIC-based products exhibit low bond strengths (BSs) for bonding orthodontic brackets [5][6][7] . Resin-modified glass ionomer cement (RMGIC) was developed with the purpose of increasing bond strength.…”

Effect of one-bottle adhesive systems on the fluoride release of a resin-modified glass ionomer

2004

dhesive systems associated to resin-modified glass ionomer cements are employed for the achievement of a higher bond strength to dentin. Despite this benefit, other properties should not be damaged. This study aimed at evaluating the short-time fluoride release of a resin-modified glass ionomer cement coated with two one-bottle adhesive systems in a pH cycling system. Four combinations were investigated: G1: Vitremer (V); G2: Vitremer + Primer (VP); G3: Vitremer + Single Bond (VSB) and G4: Vitremer + Prime & Bond 2.1 (VPB). SB is a fluoride-free and PB is a fluoride-containing system. After preparation of the Vitremer specimens, two coats of the selected adhesive system were carefully applied and light-cured. Specimens were immersed in demineralizing solution for 6 hours followed by immersion in remineralizing solution for 18 hours, totalizing the 15-day cycle. All groups released fluoride in a similar pattern, with a greater release in the beginning and decreasing with time. VP showed the greatest fluoride release, followed by V, with no statistical difference. VSB and VPB released less fluoride compared to V and VP, with statistical difference. Regardless the one-bottle adhesive system, application of coating decreased the fluoride release from the resin-modified glass ionomer cements. This suggests that this combination would reduce the beneficial effect of the restorative material to the walls around the restoration.

“…O íon fluoreto atua sobre os microrganismos cariogênicos, alterando sua fisiologia 10,19,20 . A atividade antimicrobiana dos CIVs tem sido relacionada ao baixo pH inicial, à liberação da concentração de fluoreto e de componentes químicos tais como o Al e o Fe encontrados no seu pó, e a adição de ZnSO 4 que aumenta significantemente a liberação da concentração de íon fluoreto e a inibição do crescimento de S. mutans, sem interferir nas propriedades mecânicas destes materiais 3 .…”

“…Somente o Vidrion não apresentou diferença estatisticamente significante nos dias 1 e 9 e 1 e 17. O íon fluoreto é um dos principais elementos utilizados para a prevenção da cárie dentária 9 e favorece a transformação da hidroxiapatita em fluorapatita, reduzindo a sua dissolução, que pode ser causada pela produção de ácidos da placa bacteriana 3,10 . Neste trabalho avaliou-se os níveis de liberação da concentração de íon fluoreto de 4 CIVs sendo 2 anidros e 2 modificados por resina composta.…”

Objetivo: Avaliar a liberação de íon fluoreto de 2 cimentos de ionômero de vidro (CIV) anidro e 2 modificados por resina composta antes e após recarga com fluoreto de sódio neutro a 2% por 4min. e após a proteção da superfície do CIV Maxxion R com um adesivo odontológico, um verniz cavitário e um esmalte incolor para unhas. Métodos: Com uma matriz de aço inox com 2mm x 6mm, confeccionou-se 5 corpos de prova de cada material, que foram imersos em 5mL de água deionizada, trocada a cada 24h. Foram realizadas leituras em um potenciômetro nos dias 1, 2, 9 e 17 na 1ª e 2ª etapas, e as amostras foram tamponadas com solução TISAB III. Na 2ª etapa, as amostras foram submetidas à recarga e novamente imersas em 5mL de água deionizada. Na 3ª etapa foi realizada a proteção da superfície dos CIVs e feitas leituras nos 5min., 24h, 48h e 72h. Utilizouse os testes estatísticos Post Hoc de Tukey e t Student (p<0,05). Resultados: Observou-se diferença estatisticamente significante ao comparar a 1ª com a 2ª etapas em todos os materiais, exceto no dia 2 para o Vidrion R e para o VitroFil LC. Na 3ª etapa observou-se que em todos os materiais, comparando os primeiros 5 min. com os outros tempos, as diferenças entre as médias da liberação das concentrações de íon fluoreto foram estatisticamente significantes. Ao 0comparar os demais tempos, tanto o verniz quanto o esmalte incolor para unhas apresentou diferença estatisticamente significante entre 24h e 48h, bem como em 24h e 72h. Conclusão: Os CIVs anidros tiveram maior efetividade na liberação de íon fluoreto e na recarga em comparação com os CIVs modificados por resina composta e o Maxxion R apresentou um comportamento homogêneo e estatisticamente significante nas duas etapas. Todos os materiais protetores testados foram eficazes, e o esmalte incolor para unhas apresentou o melhor comportamento.Cimentos dentários; Cimentos de ionômeros de vidro; Materiais dentários.Objective: To evaluate fluoride ion release from two anhydrous glass ionomer cements (GICs) and two resin-modified GICs (RMGICs) before and after recharge with 2% neutral sodium fluoride for 4 min and after surface protection of the Maxxion R GIC with an adhesive system, a cavity varnish and a colorless nail polish. Method: A stainless steel 2x6 mm matrix was used for fabricating 5 specimens of each material, which were immersed in 5 mL of deionized water, renewed every 24 h. Measurements with a potentiometer were performed on days 1, 2, 9 and 17, in the 1 st and 2 nd phases, and the specimens were buffered with a TISAB III solution. In the 2 nd phase, the specimens were subjected to recharge and immersed again in 5 mL of deionized water. In the 3 rd phase, the GIC surfaces were protected and readings were made at 5 min, 24 h, 48 h and 72 h. Tukey's post-hoc and Student's t tests were used for statistical analyses (p<0.05). Results: There was statistically significant difference in the comparison between the 1 st and 2 nd phases for all materials, except at day 2 for Vidrion R and VitroFil LC. In the 3 rd phase, it was obse...
