The effect of denture base resins coated with antibacterial coating on water sorption, solubility and monomer elution

Abstract

Abstract: PURPOSE: To determine the influence of denture base resins coated with antibacterial coating on water sorption, solubility and monomer elution. METHODS: The values of water sorption and solubility were measured according to YY 0270-2003 and gas chromatography was used to examine the leachability of 4 commercially available heat-cured acrylic resins between experimental group and control group. Degree of crosslinking of the experimental heat-cured acrylic denture bases were measured by soxhlet extraction method. The data was analyzed by 17.0 software package. RESULTS: The values of water sorption, solubility and monomer elution of experimental group were lower compared to the control group. Degree of crosslinking of Heraeus reins was the highest among the experimental heat-cured acrylic denture bases. CONCLUSIONS: There is a same trend among water sorption, degree of crosslinking and the monomer elution. When the degree of crosslinking increases, the values of water sorption and monomer elution decrease. Antibacterial coating can improve the comprehensive properties of the denture base resins.
