Shear bond strength of composite resin and glass ionomer cement

Abstract

The objective ofthis studywas evaluate the shear bond strength between two lightcured composite resins and two glass ionomer cements. Each Group of composite resin - glass ionomer (M1: Silux Plus - Vitrebond and M2: APH - Baseline) had 45 specimens divided into three other Groups of15 samples according to the submitted storage time: 24 h, 2 weeks and 4 weeks. Specimens were thermocycled before shear bond testing. The data was analysed and it was concluded that (1) both Groups (M1 and M2) showed similar results after 24 h storage time and (2) Graup Ml showed statistically superior resulta when longer storage times were used. Key words: shear bond strength, composite resin, glass ionomer cement.
