Ｄetails in the interaction between the acidic monomer employed in G-BOND PLUS and tooth component were examined by comparing the changes in the 13C NMR profiles obtained before and after reacted with hydroxyapatite and dentin particles using a 13C NMR technique. It was concluded that the G-BOND PLUS, which exhibited greater demineralization ratio of tooth apatite, provided the enamel bond strength but not the dentin bond strength. The bond strength of resin to the dentin seemed to decrease when4-MET in the G-Bond PLus was altered by hydrolysis in response to the prolonged storageperiod.
