Variations in powder/liquid ratio of a restorative and luting glass lonomer cement in dental clinics

ABSTRACT

A survey was conducted to ascertain the variations practiced in powder/liquid [P/L] ratio of Glass lonomer 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 [[tilde]12] and that for luting purpose [[tilde]11 to 21] may affect the performance characteristics of the material:
