The purpose of this in vitro study was to examine the effect of various powder-liquid ratios of an experimental resin-tnodified glass-iotiotner polymer cement on dye penetration when the cement was used as a pit and fissure sealant. Eighty extracted hutnan third molars were randomly assigtjed to one offour pit and fissure sealant conditions: a resin-based sealant or one of three variations in powder-liquid ratios (1.4:1.0, 1.8: 10, and 2.0:1.0) of an experimental, light-activated, resin-modified glass-ionomer cement. After sealant placement, the teeth were thermocycled and inunersed in methylene blue dye. The teeth were sectioned, and the extent of dye penetration along the sealant-enamel interface was measured linearly. The resin-sealed occlusal fissures showed statistically significantly less dye petietration than did the three powder-liquid ratios of the experimental resin-modified glass-ionomer-cement sealant.
