Resumo: | Purpose: This study aimed to compare the fluoride release from glass ionomer cements (GIC) used for orthodontic cementation, before and after fluoride recharge. Methods: Three GIC were evaluated: Meron (VOCO), Vidrion C (SS WHITE), and Ketac-Cem (3M ESPE). Fluoride release was measured by means of an ion selective electrode connected to a ion analyzer after 1 h and 1, 3, 7, 14, 21 and 28 days. To analyze the fluoride recharge and capacity of fluoride retention, the specimens were immersed in a 0.221 % sodium fluoride solution (1,000 ppm fluoride) for 5 min at days 28, 30, 31 and 32 for fluoride measurement after 24 h. Data were analyzed by ANOVA and Kruskal-Wallis test at the significance level of 0.05. Results: The pattern of fluoride release was similar for the tested GIC: all materials showed higher fluoride release at the first day and a fast decrease up to day 7. The exposure to the fluoride solution provided higher fluoride release from all materials, but the fluoride levels were not as high as in the first day. Conclusion: Overall the cements Meron and Vidrion C had larger fluoride release rates than Ketac-Cem, before and after fluoride recharge. The use of fluoride solution may increase the quantity of fluoride released from GIC. Key words: Glass ionomer cement; fluoride |

Metodologia: Foram avaliados três CIV: Meron (VOCO), Vidrion C (SS WHITE) e Ketac-Cem (3M ESPE). A liberação de flúor foi medida através de eletrodo íon seletivo conectado a um analisador de íons após 1 h e 1, 3, 7, 14, 21 e 28 dias. Para avaliação da recarga de flúor e capacidade de retenção de flúor, os espécimes foram expostos a uma solução de fluoreto de sódio a 0,221 % (1000 ppm de flúor) por 5 min nos dias 28, 30, 31 e 32 para medição após 24 h. Os dados foram analisados por ANOVA e teste de Kruskal-Wallis ao nível de significância de 0,05. Resultados: O padrão de liberação de flúor foi similar para os diferentes CIV avaliados, sendo que todos os materiais apresentaram uma maior liberação de flúor no primeiro dia e um decréscimo rápido até o sétimo dia. A exposição à solução fluoretada proporcionou maior liberação de flúor pelos materiais, mas sem atingir os mesmos níveis do primeiro dia. Conclusão: Os cimentos Meron e Vidrion C apresentaram maior liberação de flúor comparado ao cimento Ketac-Cem, tanto antes quanto após a recarga de flúor. O uso de solução com flúor permite elevar a quantidade de captação e liberação de flúor pelos CIVs.
