Estabilidade de cor e influência da pigmentação extrínseca nas restaurações de resina composta: revisão de literaturaia no contexto brasileiro

Abstract

INTRODUCTION: The evolution of aesthetic materials has had a strong tendency to accept the resinous material as one of the main chosen for the aesthetic rehabilitation of anterior teeth, however it is a material subject to pigmentation by colored foods. OBJECTIVES: The objective of this study is to verify the existence of a dye that most significantly affects the staining of composite resins used in esthetic restorations and whether there is a more effective way to mitigate the effects of pigmentation. METHODOLOGY: a literature review will be carried out with 4 databases (Pubmed, Google Scholar, Scielo and Lilacs) selected 40 publications in the time interval from 2014 to 2024, with the inclusion criterion being the relevance of the material in relation to the proposed theme. RESULTS: The results of the study showed that the main pigmenting agents of composite resins were red wine and coffee, which stood out in the pigmentation results due to secondary factors such as pH and the temperature at which the solution is ingested and not exclusively due to the properties of the dye. The importance of choosing the composition of the resin that will be used, the time of ingestion of the dye solutions and the importance of methods for maintaining the color of the restorations are also highlighted, with polishing standing out, even though bleaching has proven to be effective. CONCLUSION: This review concluded that extrinsic staining by dye is still a problem in the manufacture of composite resin restorations and that several factors are involved in the greater or lesser degree of pigmentation. It also highlighted the importance of polishing as a method of maintaining color.
