Abstract

The aim of this study was to develop an effective primer to improve the adhesive property between all kinds of dental metal alloy and resin cement. To this end, we synthesized N-N′-dimethacryloylcystine (NDMCC) which had both disulfide functional group (to improve adhesion between precious metal alloy and resin) and carboxyl group (to improve adhesion between non-precious metal alloy and resin). With the presence of SuperBond C&B, the adhesion between precious, semi-precious, and non-precious dental metal alloys and resin cement was improved when compared to the untreated controls. However, the adhesive property between all types of dental metal alloy and resin cement was not improved with Panavia 21EX. In particular, reduced bond strength in the case of non-precious metal alloy was speculated to arise from the acid-base neutralization reaction between the carboxyl group of NDMCC and the amine present in the polymerization initiator system of Panavia 21EX.
