Kinetic studies of the effect of varnish on water loss by glass–ionomer cements
Nicholson, J.W., et al. - This paper reports a study of the water loss behaviour of two commercial glass–ionomer cements coated with varnishes...Varnishes protect immature glass–ionomer cements from drying out by altering the mechanism of water loss. This slows the rate of drying but does not necessarily change the total amount of water retained. It confirms that, in clinical use, glass–ionomer restoratives should be varnished to allow them to mature satisfactorily [more...]
