The significance of the Water Balance in Glass-Ionomer.
J Pak Dent Assoc Jan ;11(4):197-202.

Glass ionomers cements (GICs) are materials of high value in dentistry. However one significant weakness is their initial instability due to water update or water loss. This article serves to highlight the mechanisms responsible for the change in water content as well as the subsequent impact on its properties. Methods of minimizing this impact are advocated to improve its performance as a restorative material.
