Influence of food pigments on restorations

Abstract

Aim and objectives: to observe the influence of food pigments on composite diacrylic resin restorations and to evaluate the chromatic stability of the aesthetic materials that we used. Material and methods: discs of a single type of DRC shade A2 and A3 were used. Initially, pre-immersion color measurements of the composite samples were performed. The composite samples were immersed in various pigmented solutions (tea, coffee, distilled water) for 24 hours and 7 days, the evaluation and observation of the degree of discoloration of the restorative materials being done every 24 hours and 7 days Results: According to the results, it was found that the largest color change on the surfaces of the composite material was recorded for tea and coffee after immersion for 7 days. Tea and coffee significantly affected the color of the composite samples used in the study. Conclusions: The effect of pigmented solutions (tea, coffee) that caused discoloration in the composite diacrylic resin was closely related to both the established immersion time (24 hours and 7 days) and the shade of the material used (A2 and A3).
