Glass ionomers in proximal cavities of primary molars

Abstract
Proximal cavities with or without a dovetail were prepared in primary molars of 5-7-yr-old children. The cavities were filled with either a traditional glass ionomer (Ketac-Fil) or a cermet (Ketac-Silver). A total number of 199 treated teeth were available for evaluation 5-14 months after placement of the fillings. The percentage of success was 84% for Ketac-Fil and 77% for Ketac-Silver. There was no clear difference in success rate between the two different types of cavities.
