RESUMO

Objetivo:

O objetivo desse estudo in vitro foi comparar a sorção (SO) e a solubilidade (SB) em água de sistemas adesivos e resinas compostas baseados em seus grupos funcionais dos monômeros. Material e

Métodos:

Três sistemas adesivos (Adper Single Bond 2 – 3M ESPE, Clearfil SE Bond – Kuraray, sistema adesivo da P90 – 3M ESPE) e três resinas compostas (Filtek Z350 – 3M ESPE, Filtek Z250 – 3M ESPE, Filtek P90 – 3M ESPE) foram testados. Oito espécimes de cada material foram preparados para avaliar a SO e SB. Inicialmente, os discos foram individualmente armazenados em um dessecador até a obtenção de uma massa constante e, em seguida, armazenados individualmente em água destilada até a massa se estabilizar novamente. Finalmente, os espécimes foram secos novamente no dessecador até uma massa constante ser obtida. SO e SB foram calculadas a partir dessas mensurações.

Resultados:

Os dados foram analisados pelo teste de ANOVA a 1 critério e teste de Tukey (p < 0,05). O adesivo do sistema P-90 apresentou os menores valores de SO e o Clearfil SE Bond apresentou os menores valores de SB. A resina composta Filtek P-90 apresentou os menores valores de SO e SB.

Conclusão:

Baseado nos resultados, pode-se concluir que a sorção e a solubilidade foram influenciadas pela composição dos materiais. O principal grupo funcional dos materiais determina a suscetibilidade à água e influencia o seu desempenho.
ABSTRACT

Objective:

The objective of this in vitro study was to compare dentin bonding systems and composite resins based on their functional groups in terms of water sorption (WS) and water solubility (WSB). Material and

Methods:

Three dentin bonding systems (Adper Single Bond 2 – 3M ESPE, Clearfil SE Bond – Kuraray, P90 Adhesive System – 3M ESPE) and three commercial composite resins (Filtek Z350 – 3M ESPE, Filtek Z250 – 3M ESPE, Filtek P90 – 3M ESPE) were tested. Eight specimens of each material were prepared to evaluate the WS and WSB. The discs were individually stored in a desiccator until constant mass was achieved. Specimens were then individually stored in distilled water until the mass was stabilized again. Finally, the specimens were dried again in the desiccator until constant mass was obtained. WS and WSB were calculated from these measurements.

Results:

Data were analyzed by oneway ANOVA and Tukey post hoc test (p < 0.05). Filtek Silorane-Bond presented the lowest values of WS, and Clearfil SE Bond presented the lowest WSB. Filtek Silorane resin showed the lowest WS and WSB results.

Conclusion:

Based on the results, it can be concluded that the WS and WSB were influenced by the composition of the materials. The main functional group of the materials determines their susceptibility to water and influences their performance.
