“…e weighting method is used to evaluate the seasonal color matching results of each landscape unit case [6]. Asdagh et al studied the color matching between the composite resin used for repair and the initial composite resin restoration after the aging process [7]. In the research of these researchers, most of them are doing research on the practical application of multimedia and visual communication, and they lack the research on these technologies themselves.…”

The obvious tendency of modern artists to change the concept of painting is to pay more and more attention to personal feelings and spiritual expression. In modern oil paintings, there are more and more oil paintings that convey emotions and the emotional expression methods of the colors of the works are becoming more and more abundant. This article aims to study the application of multimedia visual communication in the texture and color matching of oil painting creation materials and to put forward the viewpoint of applying more multimedia visual communication to oil painting creation. This article first gives a detailed introduction to oil painting creation materials and their texture, oil painting color matching, and so on. In addition, experiments were conducted on the application of multimedia visual communication in the texture and color matching of oil painting creation materials. The experimental results show that the texture and color matching of oil painting creation materials based on multimedia visual communication are more popular with the public, and oil painters are also satisfied with this method. And, the expressiveness of oil painting texture has been improved by 10%. This shows that the texture and color matching scheme of the oil painting material in this study is effective.

Aim To in vitro evaluate the bleaching effect on the color match of Omnichroma composite resin restorations to the teeth color. Materials and methods Thirty freshly extracted intact human premolars were collected and mounted in acrylic resin blocks (only roots were embedded). The shade of the selected teeth was measured by (VITA Easyshade V). Class V cavities (4 mm width, 2 mm length, and 2 mm depth) were prepared 2 mm coronal to cement-enamel junction on the cervical third of the facial surface of each tooth. Specimens were randomly divided into two equal groups (n = 15): group I: was restored with nano hybrid Tetric N- ceram while group II: was restored with Omnichroma supra-nano filled composite resin using their respective adhesives. All the specimens were thermocycled for 500 cycles from 5 to 55°C with 15 s dwell time, and 20 s transfer time. The initial data of color measurements for tooth and restoration surfaces were recorded after thermocycling using VITA Easy Shade V. Specimens were then bleached using 40% HP by White smile power whitening YF according to the manufacturer instructions and kept in artificial saliva for 1 week before color re-measuring. All data were collected, tabulated, and statistically analyzed at 95% significance level using a software statistical package for social sciences (SPSS version 26). Results Before bleaching, higher mean ΔΕ values were recorded for the teeth (3.38 and 2.74) compared to (2.24 and 1.82) of the restorations in group I (Tetric N) and group II (Omnichroma) respectively with no statistically significant difference (P = 0.26 and 0.43) in either of the groups denoting the color match between the restorations and the teeth in both groups. After bleaching there was a highly statistically significant difference (P = 0.039) between the mean ΔΕ values of teeth (5.56) and restorations (3.23) in group I, denoting the color mismatch. While in group II there was no significant difference (P = 0.249) between the values of teeth (5.25) and restorations (4.49) denoting the persistence of the color match after bleaching. No significant difference was found between the ΔΕ values of teeth used in both groups neither before (P = 0.62) nor after bleaching (P = 0.802). While there was a significant difference between the recorded values of the restorations after bleaching (P = 0.026) although the difference was not significant before bleaching (P = 0.619). Bleaching significantly affected the teeth color (P = 0.013 and 0.038), and the restoration color (P = 0.049 and 0.012) in groups I and II, respectively. Conclusions Omnichroma class V composite restorations matched the shades of teeth before and after bleaching where it was changed to a lighter shade with the teeth enamel that was within the acceptable clinical range. The color matching of the Tetric N restorations after bleaching was lost where the teeth were lighter in a clinically detectable manner, which necessitates restoration replacement.
