Color change, water sorption and solubility of two types of denture liners incorporated with carbon nanoparticles

Abstract

Objective: The aim of this manuscript was to investigate the effect of carbon nanoparticles (CNs) addition into denture liners on the color change and water absorption and solubility. Materials and Method: Test specimens (n=10) of Visco-Gel (Group VG) and Ufi-Gel (Group UG) were created either without (Groups C-as control and W) or with the incorporation of 0.5%, 1% and 10% CNs synthesized from licorice root plant. The size of the CNs were measured with dynamic light scattering. The color of each specimen was measured with a spectrophotometer. Water sorption and solubility were determined by weight measurement. The data were analyzed by two-way ANOVA for sample size estimation and Mann-Whitney U and Kruskal-Wallis tests for analyses of main outcomes with significance at the p<0.05 level. Results: All CNs-added test groups showed statistically higher color change than control groups (p<0.0125). In Group UG, 10% CNs added test groups showed statistically higher water sorption and solubility values than Group C, W and 0.5% CNs added test groups (p<0.001). However, the addition of 0.5% and 1% CNs to Groups VG caused a statistical decrease in water sorption values compared to control groups and Group VG 10% (p<0.001). Conclusion: Color change of CNs added denture liners were not within clinically accepted range of color difference regardless of addition rate. CNs addition in tested denture liners promoted changes in the liners’ sorption/solubility. UG was more prone to increase in both water sorption and solubility than VG.
