EVALUATION OF SPECTROPHOTOMETER ANALYSIS OF BULK-FILL COMPOSITES IN VARIOUS DAILY USED BEVERAGES

The visible color alterations in esthetic materials can also be ascribed to the proprietary differences in chemistry that may affect the polymerization, water sorption, and consequently the color stability of the material. In addition, the obvious effect of colorants in beverages and foods leads to extrinsic discoloration of composites. Thus, for suitable performance, longevity and good clinical success of esthetic restorations, the material of choice should present adequate inherent characteristics. The discoloration of tooth-colored, resin-based materials may be caused by intrinsic or extrinsic factors. Visual or instrumental techniques can be used to evaluate discoloration. The use of instrumental methods like spectrophotometers and colorimeters to quantify tooth color could potentially eliminate the subjective aspects of color assessment. Hence based on above findings the present study was planned for evaluation of spectrophotometer analysis of bulk-fill composites on various daily used beverages. The present study was planned in Department of Conservative Dentistry and Endodontics, Buddha Institute of Dental Sciences and Hospital, Patna, Bihar. The color of composite resins can be determined by varying methods, including visual assessment and instrumental measurement by a spectrophotometer. According to the Spectrophotometer results of this study, material tested became changes in color after immersion in the beverages. The data generated from the present study concludes that all the beverages used in this study changes in color in the material tested. Coca-Cola causes more color changes than other beverages in the material tested. The total changes of color after 1, and 7 days of composite immersion in coca cola were higher than the clinically acceptable threshold, and they are comparable to the color changes observed with coffee, tea, orange juice and beer, which are known as strong staining agents.
