“…The different chemical contents and mechanical properties of resin composites imply that many different factors influence their clinical performance [39]. SsURC, having specific color-matching mechanisms through their filler structures, can exhibit different mechanical and clinical behaviors [24].…”

Single-shade universal resin composites (SsURC) are preferred in clinical practice to reduce time for shade selection and obtain good esthetic results. In this study, the static mechanical properties of seven new SsURCs were investigated, their spectral analyzes were performed and scanning electron microscopy (SEM) evaluations were presented. Charisma Diamond One/DO, Admira Fusion x-tra/AFX, Omnichroma/OC, OptiShade/OS, Essentia Universal/EU, Zenchroma/ZC, Vittra APS Unique/VU were used in a three-point bending test to determine flexural strength (FS) and elastic modulus (EM); Vickers micro-hardness (VHN) and hardness-ratio (HR) were performed with a micro-hardness tester from top/bottom after 24-h/15-days of storage in distilled water at 37°C (±1 °C). The degree of conversion (DC) was assessed by using Fourier transform infrared spectroscopy (FTIR). The structure of the resin matrix and filler content were assessed by SEM. Data were analyzed using IBM SPSS V23 and the R program and the significance level was taken as p < 0.05. The main effect of the tested SsURCs was found to be statistically significant on FS, EM, VHN, and DC values (p < 0.001). Bis-GMA free SsURCs (AFX, DO, VU) showed better DC and HR except for OC. All seven tested SsURCs conform to the requirements of ISO standards for dental resin composites for all tested categories.

At the beginning of the 90 s on the market of dental restoration materials appeared compomers, polyacid modified composite resins (PMC). The term compomer suggests a combination of glass-ionomer and composite technology. This has led to confusion about how it relates to dental structures. The properties and adhesion of compomers to dental structures suggest a closer connection with composites than with glass ionomers. They do not have direct chemical adhesion to any tooth structure it adheres similar to the composites through a separate binding agent. However, their proximity to composites does not make them substitutes of composites. Compomers are a versatile class of dental restorative biomaterials, whose clinical benefits are particularly useful in pediatric dentistry.

ObjectiveThe purpose of this study was to evaluate the effect of aging and fiber‐reinforcement on the color stability, translucency, and microhardness of single‐shade resin composites versus multi‐shade resin composite.Materials and MethodsFour resin composites (Filtek Z250, Omnichroma, Vittra APS Unique, Zenchroma) were tested. Three subgroups of specimens were prepared for each of the composites: control, polyethylene fiber‐reinforcement, and glass fiber‐reinforcement‐ groups (n = 10/per group). The samples were subjected to aging for 10,000 thermal cycles. Color differences (ΔE00) were calculated after aging. Relative translucency parameter (RTP00) and microhardness values were calculated before and after aging. A two‐way analysis of variance and the generalized linear model was used (p < 0.05).ResultsThe lowest and highest ΔE00 values were found for Filtek Z250 (0.6 ± 0.2) and Omnichroma resin composites (1.6 ± 0.4), respectively. The ΔE00 value of the polyethylene fiber‐reinforcement group (1.2 ± 0.6) was significantly higher than the ΔE00 value of the glass fiber‐reinforcement group (1.0 ± 0.4, p < 0.001). The RTP00 value of the glass fiber‐reinforcement group (1.92 ± 0.78) was significantly higher than the RTP00 value of the polyethylene fiber‐reinforcement group (1.72 ± 0.77, p < 0.001). The highest microhardness values were found in glass fiber‐reinforcement group (76.48 ± 17.07, p < 0.001).ConclusionSingle‐shade resin composites were more translucent, had higher color change, and lower hardness than multi‐shade resin composite. For relative translucency and microhardness, statistical significance was found in the material and fiber type interaction. The glass fiber‐reinforcement provided higher translucency, lower color change and higher microhardness values than polyethylene fiber‐reinforcement group after aging. Thermocycling had a significant impact on the color stability, translucency parameter, and microhardness of the tested resin composite materials.Clinical SignificanceSingle‐shade resin composite materials have greater color‐changing potential. The glass fiber‐reinforcement optimize resin material mechanical properties and color stability more than polyethylene fiber‐reinforcement.
