Dataset on shear bond strength of silver nanoparticles coated denture base resin to autopolymerizing repair resin
Recently, silver nanoparticles have been synthesized and applied to several biomaterials, since their small size provides great antimicrobial effect, at low filler level. Therefore, these nanoparticles have been applied in dentistry, in order to prevent or reduce biofilm formation over dental prosthesis surfaces. In addition, there is a method of coating the denture with silver nanoparticles. However, the influence of silver nanoparticles coating has not been reported on the bond strength between denture base resins coated using its and autopolymerizing resins. The purpose of this study is to investigate the effect of silver nanoparticles coating on the bond strength between heat-polymerized denture base resin (Acron, GC) or autopolymerizing denture base resin (Palapress® vario, Kulzer Japan Co., Ltd.) and autopolymerizing repair resin (Unifast Ⅲ, GC). Half of the specimens were coated with silver nanoparticles. The other half without treatment were used as a control group. All the specimens were immersed in 37℃ water for 24h. The shear bond strengths were determined using a universal testing machine. The fracture modes of the examined specimens were observed and determined. In addition, a scanning electron microscope was used to obtain micrographs to examine surface properties of each specimen. The measured shear bond strengths were statistically analyzed using t-test. The measured shear bond strengths were statistically analyzed using analysis of variance (ANOVA), followed by Tukey’s post hoc comparison test.
