Susceptibilidad a la tinción de diferentes marcas de resina compuesta.

Abstract

Introduction: Composite resins are one of the most important advances in modern dentistry, however, one of their greatest defects is their susceptibility to staining to different factors, both intrinsic and extrinsic. This study aims to determine the staining susceptibility of each commercial brand of composite resin included in the study. Materials and methods: To carry out this study we used 4 resins of different A2 color brands: Dentsply Spectra, FGM Opallis, Ultradent Forma and FGM Llys. They standardized by making 16 discs of 5 mm x 2 mm for each resin, giving a total of 64 discs. The liquids used for this study were: Coffee, Red Wine and Black Soda, for the control group artificial saliva was used. The coloration was measured using the Adobe Photoshop program that will give us the RGB and CieLAB codes, a measurement was made after being exposed on days 0, 3, 6 and 12. The results were tabulated in Excel and the statistical tests were performed in the SPSS program. Results: The liquid that had the greatest pigmenting effect on the resins was wine on days 6 and 12, and the resins had different changes depending on the liquid to which it was exposed. Conclusion: It was concluded that the resins had different susceptibilities to the liquids used in the study, demonstrating that there are differences in susceptibility between the different brands of resin.
