title: Bond durability between dentinal bonding agents and tooth structure.
abstract: Glass-ionomer cements and dentinal bonding agents have made possible cavity preparations without mechanical retention. However, durability of bond strength is critical to the longevity of these restorations. This research evaluated the durability of the chemical bond formed by four materials attached directly to tooth structure. Tenure bonding agent recorded the strongest bond at each thermocycling time. In addition, whereas the bond strength remained unchanged for Scotchbond bonding agent, Ketac-Bond glass-ionomer cement, and GC lining cement, bond strength for Tenure bonding agent increased with thermocycling.
