Cambios en la pigmentación de resinas utilizadas en carillas en el sector anterior sumergidas en diferentes medios acuosos

Abstract

The objective of this study was to determine the composite resin brand that has better pigmentation properties for use in direct veneers in the previous sector. An experimental in vitro study was conducted to evaluate the resin pigmentation grade of 5 commercial houses (3M ™ Filtek ™ Z350 XT, GC SOLARE, SPECTRA BASIC, FORM, TETRIC) which in turn were submerged in different aqueous media. For this, 100 resin discs (5 for each brand) were used. The resins were subjected to aqueous media for 15 and 30 days respectively to assess the quantitative change in pigmentation using the Vitaeasy shade® equipment. Statistical analyzes were performed in the STATA 14.0 program. As results, no differences were observed in the pigmentation evaluated at 15 or 30 days (p> 0.91). There was a change in pigmentation between the initial value of the color and the final value in all resin brands (p <0.001). Likewise, the resins showed a change in the color value regardless of the harassment medium to which it was submerged (p <0.001). In this study, all brands evaluated showed significant changes in pigmentation when immersed in aqueous media such as distilled water, coffee, beer, red wine and black soda.
