“…Previous research has shown that the filler content, shape, and size have an effect on the color of the composite. 23,24,26 This occurs as some of the light is absorbed by the material while a part of it is reflected, which contributes to the color of the material. OM has been developed with a smart chromatic technology which, rather than relying on red and yellow pigments that are added to impart color, it uses the concept of structural color where the material itself weakens or amplifies specific wavelengths of light to blend in.…”

“…When a tooth is restored with composite resin, several factors can affect the shade match, including the filler content and size, matrix composition, the size of the restoration, layering of the composites, and the shade and the brand of the composite itself 4,5,23‐26 . In a study by Arikawa et al, composites with smaller and irregular‐shaped fillers showed higher light transmittance as compared to the ones with larger particles 24 .…”

“…Titanium oxide fillers increase the opalescence and give a more enamel-like appearance. 26 In a study conducted by Paravina et al, they concluded that the BE increased with a decrease in restoration size, a decrease in the color difference, and an increase in translucency. 4 Paravina et al also showed in another study that the BE was dependent on the shade and composite.…”

“…Otherwise, the material appears opaque, as it does not allow sufficient light to pass through. 26 In this study, the term "single-shade composite" has been used to denote a composite material available as a single universal shade, that has been developed to blend with all 16 VITA classical shades, thus providing a shade match for every tooth color. A "group-shade composite" implies a composite system available in fewer shades, with each shade being used for a recommended set of VITA classical shades.…”

Objective: To evaluate the shade match of three composite resin restorative materials to bi-layered acrylic teeth instrumentally and visually. Materials and methods: Three composite materials-Omnichroma [OM], Tetric EvoCeram [TE], and TPH Spectra ST [TS] were placed into occlusal preparations (5 mm diameter, 2 mm depth) on 15 bi-layered acrylic teeth per each shade A2, B1, B2, C2, and D3. The composites were placed in a single increment and cured using Bluephase G2 light. The L*, a*, and b* readings were obtained using VITA Easyshade V for the teeth and restorations; mean ΔE 00 values were calculated and assessed using two-way analysis of variance with a test of simple effects with multiple comparisons for significance (P < .05). Three teeth were restored to anatomical form with each of the composites for the five shades and were subjectively graded by 30 evaluators as 1-best match, 2-intermediate, and 3-poorest match. Results: In the instrumental evaluation, OM and TS showed lower ΔE 00 values for lighter shades, whereas TE showed lower and similar ΔE 00 values for all shades. In the visual evaluation, TE exhibited the best shade match for darker shades C2 and D3. OM and TS matched better with lighter shades. Conclusion: Shade matching is composite and shade-dependent. Overall, TE matched the multiple shades better than the other two materials. Clinical significance: Single and group shade composites displayed shade matching ability inferior to a multi-shade composite material, which may limit their use in highly esthetic clinical situations.

“…Besides, the colour of PVA-PPP films getting darker as the concentration of PPP incorporated into the PVA film increased. This statement can be supported by the research done by Mousavinasab SM in 2011 [19] which state that darker shades of the films contain darker pigments that absorb more light and result in lower light transmittance which result in better light barrier properties.…”

Biodegradable plastics had gained much attention among the researchers due to the arising of sustainability and environmental issues caused by petrochemical-based plastics. In this study, PVA films incorporated with pomegranate peel powder (PPP) were synthesized by using solution casting method. The effect of PPP on the surface morphology, physical properties, barrier properties and antibacterial activity of PVA based films were studied through FE-SEM, water solubility test, water contact angle test and Kirby-Bauer test. The incorporation of PPP had significantly enhanced the water solubility and surface energy of PVA-PPP films with the increasing of PPP content that caused reduction in water contact angle of the films. However, the films do not show a significant effect on the antibacterial efficacy against E.coli. In conclusion, PVA-PPP films have great potential to be used as green packaging materials for cosmetics products provided that further study on antibacterial efficacy against gram positive bacteria should be conducted.

Polymeric composite (PC) materials are multifarious materials widely used in almost all industries due to their fascinating properties of being flexible, lightweight, durable, costeffective, and easy mass fabrication in a variety of shapes and sizes. Furthermore, the thermophysical properties of these polymeric materials can be further enhanced by the addition of an appropriate amount of organic or inorganic filler. Their high refractive index renders them to be used as components in the manufacturing of optoelectronic devices and hence certain optoelectronic parameters can be tailor-made by insertion of an appropriate filler in the host polymer. PMMA is one such versatile polymer with interesting optical properties, which can be further tuned up with filler enforcement for desired applications. This review deals with such organic and inorganic filler-doped PMMA composites with enhanced optical properties. Initially, the authors throw light on general physical and chemical properties of PMMA and its suitability to incorporate various fillers and the varied approaches of PMMA filler interactions. The review addresses briefly the various techniques of synthesis and optical characterisation of these PMMA-based PC. Further it attempts to summarize the underlying theories and concepts that construe the correlation between structure and optical parameters. The introduction of filler to bring a change in optical behaviour as desired is a challenging one. Hence authors have included not only the present state of art of these materials and the challenges thrown but also how the researchers are aiming to mitigate them in future.
