Abstract

Aim: This in-vitro Study evaluated the Color Stability of Universal Shade (IvB) Bulk-fill Composite resin in Different Beverages in different time interval.
Materials and Methods: 60 cylindrical samples were prepared in metal ring mould (10 mm internal diameter and 4 mm height). Specimens of the Bulk-fill composite resin were randomly divided into 6 groups and stored in artificial saliva for 7 days. Specimens were immersed in Distilled Water, Coca Cola, Coffee, Tea, Orange Juice, Beer solution 100sec/per day and kept in artificial saliva between each cycle. The samples were stored in incubator at 37 degree Celcius, 100 percent relative humidity. Measurement of color changes of each sample were carried out at baseline, 24 hours (1 day), and 168 (7 days) after immersion in staining solutions, with a reflectance spectrophotometer under the D65 (daylight) illuminant over a white background using CIE L* a* b* parameters and the readings were recorded.
Results: When a day-wise comparison of color stability in the Bulk fill resin composite, the following was observed on day 1, the spectrophotometer reading in bulk fill composite were maximum with coca cola and least in beer. On day 7, the spectrophotometer reading in bulk fill composite were maximum with coca cola and least in beer.
Conclusion: Coca cola exhibited significantly more staining susceptibility than that of Coffee, Tea, Beer, Orange Juice (???? < 0>
