ABSTRACT
The present investigation was performed to determine the effect of substrate age on the microleakage of two new dentine adhesive agents. Class 5 preparations were placed at the cemento-enamel junctions of two groups of extracted human molar teeth which had been stored in water for less than 3 months or for approximately 18 months. Silux Plus was used to restore cavities that had been primed with either Scotchbond 2 or GLUMA. The restored teeth were thermally stressed for 100 temperature cycles and placed in a dye solution for 24 h. Leakage was measured under a microscope at X50 magnification. Under the experimental conditions, there was no significant difference in microleakage which could be attributed to the two different post-extraction tooth storage periods.
