Resumo
O objetivo deste estudo foi avaliar in vivo, direta e indiretamente, o desempenho clínico de dois cimentos de ionômero de vidro de alta resistência – Ketac Molar (3M) e Fuji IX (GC Int. Corp.) – utilizados no Tratamento Restaurador Atraumático. Um total de 82 crianças entre 6 e 9 anos de idade foram incluídas no estudo. O desempenho das restaurações e dos selantes foi avaliado no baseline, 3 e 6 meses após a realização dos procedimentos. As alterações das restaurações e selantes foram comparadas entre os materiais e entre os períodos de avaliação. A análise da chance acumulada de sucesso para as restaurações foi maior para Classe I do que para Classe II utilizando-se o Fuji IX, sendo verificado similar desempenho para as restaurações em Ketac Molar, porém com menor chance de ocorrência de sucesso. Não houve diferença no desempenho dos materiais utilizados tanto nas restaurações Classe I e Classe II como nos selantes. Concluiu-se que ambos os cimentos após 3 e 6 meses obtiveram alto índice de sucesso, exceto em restauração Classe II, não havendo diferença estatística entre os materiais. Apesar de ter havido perda precoce do selante para ambos os materiais, houve alta taxa de sucesso em relação à prevenção de lesões de cárie.

Abstract
The objectives of this study were to evaluate in vivo, directly and indirectly, the clinical performance of two glass ionomer cements of high resistance, Ketac Molar (3M) and Fuji IX (GC Int. Corp.) used in the Atraumatic Restorative Treatment. A total of 82 children age between 6 and 9 years old had been included in this study.
The performance of the restorations and the sealants was evaluated in baseline, 3 and 6 months after the accomplishment of the procedures. The alterations of the restorations and sealants had been compared between the materials and periods of evaluation. The analysis of the accumulated rate of success for the restorations was higher for Class I than those for Class II using Fuji IX, being verified similar performance for the restorations using Ketac Molar, however with less chance of possibility of success. There was not difference in the performance of the materials used in the restorations class I, II and in the sealants. It was concluded that both cements after 3 and 6 months showed high rate of success, except in class II, did not showing significant statistically difference between the materials. Although of early loss of the sealant for both the materials, it was observed high rate of success in relation to the prevention of caries lesion.
