What is done to the dentinal surface following etching?

Question

Quizplus · Accepted Answer

Following etching,the dentin surface must be moist to keep the collagen fibrils fluffed up.If the dentin is dried,the collagen fibrils collapse and form a dense surface that occludes the tubules and blocks adequate penetration by the dentin bonding resins.Incomplete sealing of the dentinal tubules occurs and a much weaker bond results,because the dentin/resin interface will fracture more easily.
