“…Glass ionomer cement is widely used in Class III as well as Class V preparations in the anterior teeth due to its favorable esthetic and biological characteristics along with ease of handling [7]. Recently, a new Glass ionomer restorative material, GIC Fuji IX GP Extra (GC Corporation, Tokyo, Japan), that utilizes SmartGlass™ technology imparting better esthetic qualities compared to original GIC Fuji IX GP (GC Corporation, Tokyo, Japan) was introduced in multiple shades.…”

To compare the color stability of Cention N, Fuji IX GP Extra, and Fuji IX GP after thermocycling. Material and Methods: Ten discs of each material of dimension 10 x 1 mm were prepared using a split mold. The preparations of the specimens were done according to the powder/liquid ratio as recommended by the manufacturers [4.6:1, 3.4:1 and 3.6:1 for the groups I, II, and III, respectively]. After setting, the samples were retrieved, and the thickness of each specimen was measured using a micrometer at five different locations. The specimens with variations in thickness, porosity or cracks were discarded and thus not included in the study. The selected specimens were stored in distilled water for 24 hours prior to testing. The prepared specimens were thermocycled at 5°C and 55°C, with a dwell time of 15 seconds for 250 or 500 cycles. Subsequently, the color parameters of the discs were measured using a spectrophotometer. The data were analyzed using two way ANOVA test, and a p-value <0.001 was considered. Results: Thermocycling resulted in changes in the color of both Glass Ionomer cement and Cention N (p<0.001). Among the materials tested, Cention N showed superior color stability. Conclusion: Cention N exhibited better color stability compared to Glass ionomer cements.

“…After cavity prepared the teeth were rinsed and dried, and moist cotton pellet was placed in the cavity to prevent complete dehydration of the tooth, cavity conditioning was carried out using 20% acrylic acid (GC, Tokyo-Japan) for 10 s by micro brushes and rubbing movements. Then, cavity was rinsed using water spray for 15 s, after that, a piece of cotton was placed in the cavity and gently dried for 5 s using air spray; then, the cotton was removed to prevent complete dehydration (13,14) .…”

Aim:The aim of this in vitro study was to assess and compare the effect of the nano-coating on microleakage of different capsulated conventional glass ionomer cement (CGIC), resin-modified glass ionomer cement (RMGIC) and hybrid glass ionomer cement in primary molars. Materials and Methods:A total of 36 primary molars samples were divided into three groups. Group 1 -teeth restored with capsulated RMGIC (Fuji II LC) without nano-coating. Group 2 -teeth restored with capsulated CGIC (Fuji IX) with nano-coating. Group 3 -teeth restored with capsulated hybrid glass ionomer (Equia Forte) with nano-coating. Microleakage was tested using immersed the teeth in 2% methylene blue dye penetration for 24 hours after the thermocycler and measured at x40 magnification under the stereomicroscope. Results:The results of this in vitro study showed that coating with nano-coating showed a reduction in microleakage in hybrid glass ionomer (Equia Forte) and more microleakage in non-coating RMGIC (Fuji II LC) but also more microleakage in coating CGIC (Fuji IX), which was statistically significant. CGIC with nano-coating and RMGIC without coating showed highest microleakage followed by hybrid glass ionomer (Equia Forte) with coating. Conclusion:Significant reduction in microleakage was seen in Equia Forte (hybrid glass ionomer) with nano-coating and the coating should use with all types glass ionomer.

“…A microinfiltração pode ser definida como a passagem de bactérias, fluidos, moléculas ou íons entre a parede da cavidade e o material restaurador aplicado a ela. Esta pode causar dor pós-operatória, descoloração das bordas da cavidade, cárie secundária e inflamação pulpar, resultando em falha pós-operatória (Unnikrishnan et al, 2019). Por esse motivo, vários estudos têm sugerido o uso de um pré-tratamento da superfície do dente antes de colocar o CIV (Lugassy et al, 2018); com o objetivo de eliminar a smear layer e a contaminação da superfície.…”

Introdução: A técnica sanduíche é um procedimento que combina o cimento de ionômero de vidro (CIV) com a resina composta (RC) com a finalidade de obter as melhores propriedades físico-mecânicas e estéticas de cada um. Objetivo: realizar uma revisão literária sobre a utilização desse método nas restaurações diretas e analisar como ocorre a interação entre os dois materiais. Metodologia: Foi realizada uma busca da literatura publicada entre 2010 a 2021 nas bases de dados PubMed/Medline, SciELO, Lilacs e Google Acadêmico, através da utilização de descritores pré-selecionados. Foram incluídos 40 estudos que respeitaram os critérios de inclusão e exclusão. Resultados: a associação do CIV a RC traz à restauração direta os benefícios de proteção pulpar, efeito anticariogênico, menor contração de polimerização, maior retenção e melhores propriedades estéticas. Esse método pode ser classificado em aberto, fechado, mediato e imediato, essas variações vão depender, respectivamente, da indicação e da forma de confecção do procedimento. Conclusão: ao realizar o condicionamento ácido da superfície do CIV convencional é preciso ser cauteloso, pois as diferenças nas reações de presa desse material e da RC pode interferir nas propriedades finais da restauração. Já o cimento de ionômero de vidro modificado por resina dispensa esse procedimento. Apesar de alguns estudiosos não sugerirem esse tipo de pré-tratamento, pela possibilidade de promover rachaduras e diminuição da sua força, pesquisas afirmam que a técnica mista pode ser realizada com eficácia ao utilizar tanto sistemas adesivos convencionais como autocondicionantes, pois não foram observadas diferenças significativas na resistência de união ao compará-los.
