Valoración de color en restauraciones de ionómeros de vidrio fotocurables expuestas a café/gaseosa : estudio in-vitro.

Abstract

INTRODUCTION: Glass ionomer has been recommended for use for several reasons, although it has limitations, such as pigmentation. Acidic beverages such as Coca-Cola and coffee can cause changes on the surface of a conventional glass ionomer. OBJECTIVE: To determine the color titration of light-cured glass ionomer restorations exposed to coffee/soda. MATERIALS AND METHODS: 80 dental organs were collected, which were restored with glass ionomers, and were immersed in coffee and soda, depending on their respective group. Initial and final photos were taken to obtain the CIE LAB analysis, the data were averaged and compared to obtain the results. RESULTS: Statistical differences were found between both types of ionomer, by means of Delta E, the Fuji II LC brand had a greater color change, the pigmenting substance that presented greater impact on the color was the soda. CONCLUSION: In glass ionomer Vitremer brand, an increase in the coloring of the restorations with soda is observed during both exposures (24 hours and 7 days); but with coffee there is a decrease in the coloring when it is submerged for seven days. On the other hand, with the Fuji brand, both pigmenting substances show a decrease regardless of the exposure time.
