    Notes: The purpose of this investigation was to determine the relative erosion/solubility for hybrid glass–ionomers and a compomer using the jet-impingement technique with lactic acid of various molarities. The materials studied included Dyract®, Duet®, Vitremer®, Advance®, Fuji-II LC®, and Fuji-I®, Ketac Cem® and Modern Tenacin® as the control. Data were analysed using anova and Tukey's comparison test. Results indicated that depth of erosion/solubility with hybrid glass–ionomers and compomers was not measurable by the normal procedure. Similarly, weight changes were not detectable at 0·002, 0·02 and 0·05 m (except for Advance® at 0·05 m). All glass–ionomers materials and the compomer revealed weight changes at 0·1 m after 24 h, in the following increasing order: Dyract®〈Fuji-II LC®=Duet®〈Advance®〈Vitremer®. It was concluded that weight loss is a better parameter to characterize these new hybrids glass–ionomers and compomers for erosion/solubility by jet-impingement. In addition, a lactic acid of minimum 0·1 m as a test solution is required to generate 24 h-data that can be measured in most laboratories and thus used for statistical comparison.
