Variations in powder/liquid ratio of a restorative and luting glass ionomer cement in dental clinics.
A survey was conducted to ascertain the variations practiced in powder/liquid (P/L) ratio of Glass Ionomer Cement (GIC) used as restorative and luting material in dental clinics of Karachi. It has been observed that in the use of GIC brands, 33% (Fuji 2) and 36% (Gold Label 2) of the dentists, did not follow the recommended P/L ratios for restorative purposes. Similarly, 67% (Fuji 1) and 29% (Gold Label 1) did not follow the recommended ratios for luting purposes. The wide variations practiced in P/L mixing ratios against the recommended ratio for restorative purpose (approximately 1:2) and that for luting purpose (~1:1 to 2:1) may affect the performance characteristics of the material.
