Estabilidad del color en 2 resinas, sumergidas en Coca-cola y asociadas a 3 sistemas de pulido. Estudio in-vitro.

Abstract

Currently, dentists are looking for optimal restorative materials that meet properties such as: color, aesthetics, hardness, resistance, longevity; To achieve durability, a good finishing and polishing protocol is essential. The objective of the study was to determine the ideal polishing system for composite resins that, when subjected to a drink, generates a smoother surface and consequently less pigmentation. For this, 20 Vittra resin discs and 20 Liss resin discs were made, with measurements of 10mm x 2mm, each group was divided into four subgroups, assigning 3 of them the TOR VM, 3M, FGM polishing systems and the last one the group. control. 24 hours later the finishing and polishing protocol was carried out, the discs were placed in labeled jars, 20ml of Coca-Cola was added and they were submerged for 24, 72 and 168 hours. A VITAPAN Classical A1 – D4 colorimeter was used for the 3 shade shots. The results obtained were tabulated in Microsoft Excel. It was concluded that both resins achieve pigmentation from the first color taking, despite having or not a polishing system prior to immersion in the drink, however, the most suitable system for the Vittra resin is TOR VM because it had a better color stability up to 168 hours and for the LISS-type resin there is no adequate polishing system since there are significant differences in all of them.
