Third generation dentin bonding agents: a microleakage study

This article examines and compares the extent of microleakage after 24 hours in freshly extracted teeth using three newer or "third generation" dentin bonding agents. Gluma/Pekalux and Scotchbond 2/Silux were more effective in preventing microleakage in cementum/dentin margins than was Universal Bond/Prisma Micro-fine.
