Abstract

Objective: This study analyzed the fluoride release/recharge and surface roughness of glass carbomer compared to other encapsulated glass ionomer cements (GICs).

Material and method: The GICs tested were Glass Fill® (GC-GCP Dental), Riva Self Cure® (RS-SDI), Riva Light Cure® (RL-SDI), Equia Fil® (EF-GC Europe). The composite resin Luna® (LU-SDI) was used as control. Five samples of each material were prepared and kept in a humidifier for 24 hours (37 °C, 100% relative humidity). Fluoride release was measured in two times: before (T1: days 1, 2, 7, 14) and after topical application of fluoride (T2: days 15, 16, 21 and 28). The surface roughness was also measured in both times (T1: days 1 and 14; T2: days 15 and 28). All samples were submitted to a single topical application of acidulated fluoride phosphate (Fluor Care - FGM). Two-way ANOVA with repeated measures and Tukey's post-test (p <0.05) were used in the statistical analysis.

Result: Equia Fil presented the highest fluoride release in both evaluation periods, with a higher release in T1 (p <0.05). The other materials tested, including glass carbomer presented similar release in both periods (T1 and T2). Regarding surface roughness, no significant differences were observed in the interaction between the material × time factors (T1 and T2) (p=0.966).

Conclusion: The GICs tested presented fluoride release and recharge ability and showed no surface roughness increase by topical application of fluoride.

Resumo

Objetivo: Este estudo analisou a liberação/recarga de flúor e a rugosidade superficial do carbômero de vidro em comparação a outros cimentos de ionômero vidro (CIVs) encapsulados.

Material e método: Os CIVs testados foram o Glass Fill® (GC-GCP Dental), Riva Self Cure® (RS-SDI), Riva Light Cure® (RL-SDI), Equia Fil® (EF-GC Europe). A resina composta Luna® (LU-SDI) foi empregada como controle. Cinco amostras de cada material foram confeccionadas e mantidas em um umidificador durante 24h (37 °C, 100% de umidade relativa). A liberação de flúor foi aferida em dois tempos: antes (T1: dias 1, 2, 7 e 14) e após aplicação tópica de flúor (T2: dias 15, 16, 21 e 28). A rugosidade superficial também foi aferida nos dois tempos (T1: dias 1 e14; T2: dias 15 e 28). Todas as amostras foram submetidas a uma única aplicação tópica de flúor fosfato acidulado (Flúor Care - FGM). ANOVA dois fatores com medidas repetidas e pós-teste de Tukey (p<0,05) foram empregados na analise estatística.

Resultado: O Equia Fil apresentou a maior liberação de flúor em ambos os períodos de avaliação, com liberação maior no T1 (p<0,05). Os demais materiais testados, incluindo o carbômero de vidro, apresentaram liberação semelhante em ambos os períodos (T1 e T2). Em relação à rugosidade superficial não foram observadas diferenças significativas na interação entre os fatores material × tempo (T1 e T2) (p=0,966).

Conclusão: Os CIVs testados apresentaram capacidade de liberação e recarga de flúor e não mostraram aumento de rugosidade superfícial pela aplicação tópica de flúor.
