Color stability of self-adhering composite resins in different solutions

Abstract

Background. The success of composite resin restorations depends to a great extent on their color stability. However, discoloration is still a problem in composite resin restorations. Objectives. The aim of the study was to evaluate the effect of different staining solutions on the color stability of composite resins. Material and methods. A total of 96 composite disks, 2 mm in height and 8 mm in diameter, were fabricated of 3 commercially available composite resins. The samples were divided into 4 groups of 8 and were immersed in 4 staining solutions: coffee, tea, soda, and artificial saliva. The color parameters of the samples were measured and recorded before as well as 2, 4 and 8 weeks after immersion by spectrophotometry, using the CIELAB color space. A color change (ΔE) ≤3.3 was considered the acceptable threshold for visual perception. The results were analyzed using the one-way analysis of variance (ANOVA) and Tukey's post hoc test (p < 0.05). Results. All the composite resins in the study showed discoloration in all the staining solutions. The ΔE of Vertise TM Flow was the highest in the tea solution. The lowest ΔE occurred in the Filtek TM Z250 composite in artificial saliva. Conclusions. This in vitro study showed that the color stability of tooth-colored restorations can be influenced by dietary habits.

Effects of photoinitiators on dental composite resins: a narrative review

“…Composite resins are esthetic restorative materials commonly used in dental clinics [10], Trevisan et al [11] state that it is currently a material of choice for direct anterior and posterior restorations due to its ease of handling, preservation of dental tissue, structural reinforcement, adhesion, low cost and especially the natural appearance of these materials. With the constant evolution of dental materials, conservative treatment has become increasingly viable, mainly because it offers advantages such as dental preservation, less working time, low cost (when compared to ceramic), and providing aesthetic results as satisfactory as [12].…”

Color Stability of Orthodontic Ceramic Brackets and Adhesives in Potentially Staining Beverages—In Vitro Study

“…Today's high consumption of food and beverages full of natural and synthetic colors can result in the unsatisfactory esthetic performance of dental materials. Previous studies confirmed that esthetic brackets and adhesives are not color-stable in the long term and are susceptible to pigments commonly found in food and drinks [2][3][4][5][6][7][8][9][10].…”

“…Intrinsic discoloration depends on the degree of polymerization of resins and adhesives, water absorption, the composition of the material, and the size and content of filler particles [ 3 , 5 , 7 ]. Moreover, UV radiation, changes in temperature and humidity, and aging of the material are also potential threats to the color stability of esthetic brackets and composite resin [ 6 , 8 , 9 , 10 ].…”
