Background: The aim of this study was to assess the effect of bonding application time on the microleakage of Class V sandwich restorations. Methods: Eighty non-carious third molars were randomly divided into 16 groups. Two Class V cavities were prepared on the buccal and lingual surfaces of teeth. Three groups were restored with Fuji II GIC and treated with a total-etch bonding system (Stea ⁄ SDI) immediately after insertion, at 7 minutes and 15 minutes after mixing the glass ionomer cements (GICs). Another three groups were restored with Riva Self Cure GIC and treated with the total-etch system identically. The other six groups were subjected to self-etching bonding (Frog ⁄ SDI) after GIC placement in an identical procedure. The remaining groups were made using light cure GICs (Fuji II or Riva Light Cure) in conjunction with the total-etch or self-etching systems. Cavities were then restored with composite (Valux plus, 3M ⁄ ESPE). Samples were subsequently immersed in 2% methylene blue solution for 48 hours and observed under a stereomicroscope after sectioning. Four-scale grading was used to assess microleakage in occlusal and gingival walls. Data were analysed using Kruskal-Wallis and Mann-Whitney tests. Results: The self-etching bonding system exhibited more microleakage in occlusal margins regardless of time. Over time, microleakage significantly decreased in gingival margins in all self-cure groups except for Riva Self Cure treated with the total-etch system (p < 0.05). Conclusions: Bonding application time had no effect on the microleakage of occlusal margins. However, maturation of GICs induced a decreased microleakage in gingival margins.

“…The method was first reported by Douglas and Zakariasen (1981) [16]. The advantage of this method is that it is a quantitative method and thus eliminates errors in subjective operator evaluations used in qualitative measurements [17]. This method utilises the Beer Law to measure the concentration of dye by measuring the wavelength of light [18].…”

Objectives: To evaluate and compare the effectiveness of resin-and varnish-based surface protective agents on Glass Ionomer Cement (GIC). The different surface protective agents used were: Vaseline V R , GC Fuji VARNISH TM (varnish), G-Coat Plus TM (resin) and EQUIA V R Coat (resin). Method: Thirty-six identical specimens of GIC were made. Six specimens were used in preparation of standard solution and remaining thirty were divided into five groups with six specimens in each group. Each test specimen was coated with one of the surface protecting agent except for the control group. The specimens were immersed separately into 1 ml of 0.05% methylene blue solution for 24 h and then rinsed with deionised water and further immersed into tubes containing 1 ml of 65% nitric acid. Specimens, once completely dissolved in nitric acid solution, were filtered and centrifuged. The supernatant was used to determine the absorbance using a spectrophotometer. The effectiveness of the surface protecting agents for the GIC was recorded in micrograms of dye per specimen, where low values indicate good protection. Result: Tukey HSD test revealed that GC Fuji VARNISH TM (varnish; mean ¼ 21.25 mg/ml), G-Coat Plus TM (resin; mean ¼ 30.39 mg/ml) and EQUIA V R Coat (resin; mean ¼ 9.32 mg/ml) were statistically not significantly different to each other and were effective in protecting the surface of GIC. Significance: The study found that there was a statistically significant difference between control and GC Fuji VARNISH TM , G-Coat Plus TM and EQUIA V R Coat. The three agents were found to be equally effective in protecting the surface of GIC.

“…Desde o surgimento dos materiais adesivos a microinfiltração foi minimizada, porém, seu completo controle continua sendo a meta dos pesquisadores com o objetivo de promover maior longevidade às restaurações 9,22 , pois o sucesso clínico de uma restauração baseia-se, sobretudo, no selamento que o material restaurador proporciona às margens do preparo cavitário 2 . Acredita-se que os sistemas adesivos autocondicionantes contemporâneos reduzem o número de etapas da ligação, diminuindo o tempo de aplicação sem comprometer a durabilidade de união entre a resina e a estrutura dental 27 .…”

Para analisar a capacidade de selamento marginal de três sistemas adesivos com formas diferentes de tratamentos superficiais foram selecionados 45 incisivos bovinos, íntegros e recém extraídos. Cada dente recebeu um preparo cavitário de Classe V no limite cemento-esmalte. Os preparos foram padronizados nas seguintes dimensões: 1,5mm de profundidade e 2,0mm de diâmetro. A margem incisal foi deixada em esmalte e a margem gengival localizada abaixo da junção cemento-esmalte. Os dentes foram divididos em três grupos com 15 dentes cada. No grupo I foi utilizado o Adesivo XP Bond com dentina deixada úmida após condicionamento ácido. No grupo II o sistema utilizado foi o Adper SE Plus e no grupo lll foi aplicado o sistema adesivo Adper Single-Bond 2. Em seguida, os dentes foram restaurados com resina composta nanoparticulada Filtek – Z350 (3M). Após ciclagem térmica (300 ciclos), os dentes foram imersos em solução aquosa de Azul de Metileno 2% por um período de 3 horas. Para avaliação do grau de penetração do corante foram determinados escores de 0 a 3. A análise da penetração do corante foi realizada através de microscopia óptica e aplicado o teste Kruskal-Wallis ao nível de significância de 5%. Em esmalte e dentina houve diferença entre os grupos, porém a infiltração foi maior na dentina que em esmalte, com exceção do sistema autocondicionante.
