Heats of reactions between dentine bonding agents and tooth components.
The heat of reaction of dentine bonding agents alone and dentine bonding agents with dentine, hydroxyapatite and collagen were measured using a differential scanning calorimeter (DSC) in the isothermal mode. The bonding agents were Scotchbond and Panavia Ex adhesives, and GC Fuji-II glass ionomer cement. The heat of reaction for Scotchbond and Panavia Ex bonding adhesives were 44.3 and 6.9 mcal/mg, respectively. Furthermore, results support the view that the glass ionomer cements adhere to tooth structure by chemical bonding.
