Shear Bond Strength of Hydroxyapatite Liner to Composite Resin: Effect of Dentin Bonding Agents

Abstract

The Integrity of a restoration is very important in its long term durability. In a deep cavity which has lost significant amount of dentin and is decided to restore with composite resin there are some concerns about polymerization shrinkage, bonding of composite resin and prevention of further microleakage [1,2]. In these situations there is need to place a suitable liner or base to overcome the mentioned problems.
