This study investigated the influences of acidity, ethanol, and pigment on the optical properties, microhardness, and surface roughness (Ra) of a nanohybrid dental composite resin. A total of 108 disc-shaped specimens were fabricated using a nanohybrid dental composite and allocated into 36 different storage solutions according to the levels of pH (2.0, 3.0, 4.0, and 5.5), ethanol (0%, 20%, and 40%), and anthocyanin pigment (0%, 2.5%, and 12.5%). Measurements of the colorimetric parameter and the amount of color change (ΔE), translucency parameter (TP), microhardness, and surface roughness (Ra) were performed at 24 h (baseline), 1-, 2-, 3-, and 4-weeks. Repeated measures of analysis of variance (ANOVA) with a Tukey honestly significant difference test and Pearson correlation analysis were carried out (α = 0.05). Pigment of 12.5% or 40% ethanol significantly increased the ΔE (P < 0.001, P = 0.048, respectively). Pigment of 2.5% or 12.5% significantly decreased the TP (P = 0.001, P < 0.001, respectively). Microhardness of composite resin stored in pH 2.0, 3.0, 4.0 solution was lower than that for pH 5.5 (P < 0.001). Pigment, ethanol, and pH did not influence the Ra. TP change and ΔE, and Ra and ΔE had a significant positive correlation (P < 0.05). In conclusion, pigment and ethanol levels influenced the optical properties and acidity affected the microhardness of composite resin.

Dental Composite Resin

A composite resin (CR) with photo-polymerization is widely used for dental filling material. Because of their good esthetics, the visual inspection of restored teeth becomes difficult. In this study, the fluorescent glass/ceramics fillers containing rare earth oxides — which are well-known fluorescent materials — was prepared and applied in CR to enhance visual inspection capability with small influence in color. Eu2O3-containing Y2O3 filler (Y2O3:Eu) prepared with homogeneous coprecipitaion method showed clear fluorescence at 614nm with near ultraviolet light (385nm) excitation. The fluorescence intensity of the prepared Y2O3:Eu filler increased with increase of Eu content in the Y2O3 filler upto 15mol% of Eu content. The composite resin was prepared with the mixed filler of Y2O3:Eu filler and the conventional glass filler. The content of Y2O3:Eu was varied between 0 to 40wt% of mixed filler. The prepared composite resin also showed clear fluorescence with quite small affect to the color change and the Vickers hardness of composite resin. Therefore, the prepared rare earth oxide containing Y2O3 filler was applicable as the filler of dental composite resin.
