Abstract
Objective To compare shear bond strength (SBS) between composite resin core (CRC) disposed with three different surface treatments and glass ionomer cement (GIC), so that to provide theoretical basis for luting of crowns to CRC. Methods According to three different surface treatments, thirty blocks of CRC were randomly and equally divided into three groups: Roughening with diamond grit bur(RDB), RDB plus etching with GlumaR Etch 35 Gel(RDBE), RDB plus coating with AdperTMSingle Bond2 adhensive (RDBA). All CRC were cemented with GIC. All specimens were preserved in 37 ℃ water for 24 h, then SBS tests for eight specimens in each group were performed using a universal testing machine at a constant crosshead speed of 0.5 mrn·min-1. The surface topography of one CRC of each group was observed using field emission scanning electron microscope (FE-SEM) at 100 amplification. The interface between CRC and GIC was observed using FE-SEM at 500 amplification. Then the nature of failure was also recorded using FE-SEM at 25 amplification and the data were analyzed with a Kruskal-Wallis H test. Results The surface topography of each group and the interface between CRC and GIC observed using FE-SEM were significantly different, but significant differences on the nature of failure between groups were not found (P>0.10). SBS of each group was (4.28±0.18) MPa for RDB, (4.65±0.17) MPa for RDBE, (2.39±0.21) MPa for RDBA, respectively (P<0.01). Conclusion The SBS between CRC and GIC is affected by the surface treatments of CRC.关键词
