The microleakage of a glass ionomer cement using two methods of moisture protection.

The article presents information on a dentistry study which examines the effects of moisture protection methods on the microleakage of the glass ionomer cement. The teeth used for the study were unrestored, extracted human molars with fused roots. The teeth were stored in 10% formalin saline. Under the study, the cavity preparations in 20 teeth were conditioned with polyacrylic acid for 10 seconds. A silver-stain technique was used to observe the leakage in the two methods of moisture protection.
