“…In addition to colour alteration a number of these products also can cause superficial degradation on the composite surface by reducing its microhardness which could possibly favour more superficial staining 14 . Corroborating this theory Okte Et Al showed decreased microhardness valves of microhybrid and nano resin composite after immersion in both coffee and wine solutions 15 .…”

Composite resins are the most preferred dental materials for anterior and posterior teeth. They have an important role in aesthetic and restorative dentistry. Paramount importance of composite resins are they have an Optical appearance, glossy surface and colour stability. There are three types of composite resins Conventional(Packable), Flowable(Bulkfill),Microfill. Hybrid,Fluoride releasing composites. Color change of composite restoration in different color media during the time is a common problem in esthetic dentistry, causing the need to replace restoration and spending a great deal of cost and time to patients. The aim of this study is to present a short review of recent literature available on the association of colour stability of composite resins. The article was done after reviewing several articles on the colour stability of composite resins. The effect on colour stability of composite resins depends on type of solution exposure time and composition of material. In clinical practice, patients should be aware of the staining effects, as staining in anterior teeth may lead to unaesthetic appearance.

“…Lussi et al 12) reported that the pH of red wine ranged from 3.43 to 3.68. The low pH of beverages can affect the surface roughness of organic acid resins and increase pigment absorption 13) . Therefore, it was determined that the pigment in red wine adsorbed on the surface of the temporary resin restoration and the inherent acidity of the wine caused corrosion on the resin surface and subsequent formation of a rough surface.…”

Background: Temporary crown resins are used prior to prosthesis placement, indicating the importance of aesthetics. The aim of this study was evaluate the color stability of various staining solutions according to the color of temporary crown resins using VITA Easyshade Ⓡ V. Methods: The temporary crowns used were the powder-liquid type and included four shades. A total of 36 specimens were fabricated in the form of disks with a diameter of 1.8 mm and a depth of 2 mm. They were divided into four groups of nine each, and staining was performed for seven days by precipitation in 3 mL of three staining solutions composed of distilled water, black coffee, and red wine. Color and color stability evaluations were performed by a trained examiner using a digital spectrophotometer (VITA Easyshade Ⓡ V). Color stability was analyzed using the ΔE value.Results: Because of the color stability evaluation using the ΔE value, the difference between three and seven days was significant in the specimen I and III groups (p＜0.05). Further, post hoc analysis showed that the ΔE value of red wine was significant, indicating that the color stability in red wine was low. The ΔE values in group II between days three and seven were statistically significant (p＜0.05). Post hoc analysis showed that distilled water, coffee, and wine had the highest ΔE values on day three. On day seven, the ΔE value for wine was significant, and the color stability was low. There was no significant difference in group IV according to the staining period and staining solution; therefore, color stability was high (p＞0.05). Conclusion: This study showed that most temporary resin restorations exhibited color stability in the staining solution. The darker the color of the temporary resin restoration, the higher the color stability against extrinsic staining.

The purpose of this study is was to compare the color stability of alkasite and other restorative materials commonly used in the field of pediatric dentistry and to study a color change in response to various beverages. Test specimens of glass ionomer, resin modified glass ionomer, alkasite restorative material, and composite resin were prepared, and the color stability was measured after thermocycling. Each specimen was also subdivided into 5 groups and submerged in PBS, coffee, green tea, coke, and orange juice to analyze the color change from the original CIE <i>L*a*b*</i> values after 7, 14, 21, and 28 days. Composite resin showed the best color stability after thermocycling, followed by alkasite restorative material, glass ionomer, and resin modified glass ionomer. Submerging in various beverages for 7 days resulted in color change in all test specimens, with alkasite restorative material showing less color change than glass ionomer but greater change than composite resin. Alkasite restorative material showed the greatest color change in coffee, followed by green tea and orange juice, but almost no change in coke and PBS even after 28 days of submersion.
