“…Chan et al . [24] investigated the staining potential of coffee, tea, cola, and soy sauce on two different resin composites and reported that staining after 1 week of immersion differed significantly from all succeeding weeks, and the greatest amount of discoloration occurred during the first week, which is in agreement to the results obtained in the present study.…”

Purpose:The present study was aimed to evaluate and compare the color stability of two hybrid tooth-colored restorative materials, namely, resin-modified glass ionomer cement (GC Fuji II LC Capsules - GC Corporation, Tokyo, Japan) and giomer (Beautifil II - Shofu Inc, Kyoto, Japan) when subjected to immersion in various children's beverages.Materials and Methods:Standardized disc specimens were prepared using the test restorative materials. After preparation and rehydration of the specimens, baseline color evaluations were performed using spectrophotometer. The readings were recorded according to CIELAB color space. The experimental groups were further subdivided for immersion in orange juice, bournvita milk, and coke. Subsequent to immersion and pH cycling, new color evaluations were carried out after 1 week and 4 weeks for all the experimental groups. The mean color change values were calculated.Results:The obtained data was subjected to statistical analysis. The results indicated that giomer specimens exhibited less color change as compared to RMGIC specimens indicating better color stability. The maximum color changes were found with the use of coke for a period of 4 weeks.Conclusion:Amongst the two materials, giomer showed less color changes as compared to RMGIC indicating a better color stability.

“…glass, which has been reported to discolor with test solutions used in the present study, which is supported by Gross and Moser who reported that materials containing glass beads as filler were stained with beverages like Coffee and Tea. [789101112] The clinical relevance of the present study depends on how much color change (ΔE) is considered perceptible. It is shown that a ΔE < 1 is not considered perceptible to most subjects with normal color vision and the restorations with a ΔE as high as 3.3 and 3.7 required replacement as it is clinically perceptible color change.…”

“…This is also in general concurrence with the results of previous studies conducted by Gross and Moser and Chan, Fuller and Harmati; they concluded that staining intensity of Coffee was higher than that of Tea, Coca Cola and Water. [78]…”

Objective:The aim of this study was to compare color stability and surface topography of three different feldspathic porcelains both qualitatively and quantitatively after exposure to routinely consumed beverages over different time periods using a Spectrophotometer, Stereomicroscope and Surface roughness tester, respectively.Materials and Methods:A total of 90 plastic discs were casted to obtain metal dies for three different newer ceramic applications each on thirty samples. The color and surface roughness of these samples were measured using stereomicroscope and surface roughness tester following which they were kept in different test solutions for different durations and revaluated for color changes and surface roughness in the similar manner.Results and Conclusion:Among all the five test solutions, Coffee showed the maximum staining of the ceramic whereas maximum surface roughness was shown by the Duceram Kiss (1.48 μm) by Orange Juice which could be due to its high titratable acidity.

“…For this purpose, the immersion solutions were maintained at a constant temperature of 37uC and these experimental conditions have been used by other investigators. [1][2][3]9,10,[28][29][30] The duration of the immersion for such studies is a source of contention. Some investigators have suggested that 4 weeks should be minimal immersion time in order to assess the effect of a coloured solution on the degree of discolouration, whereas others have commented that 4 weeks is too long.…”

The purpose of this in vitro study was to evaluate the colour changes in six brands of porcelain and of acrylic teeth after their immersion in tea, filtered coffee and cola for 1 day, 1 week, 2 weeks and 4 weeks. The study comprised three brands of porcelain and three brands of acrylic teeth. Five central maxillary incisors from the six types of artificial denture teeth were distributed equally into four groups (n530) according to the four immersion solutions. Colour measurements on each tooth were made before their immersion, and repeated after 1 day, 1 week, 2 week and 4 week immersions in the four solutions using the CIE L*a*b* colour measuring system. The colourimetric data were converted to National Bureau of Standards units. The data were analysed statistically by repeated measures analysis of variance (ANOVA), one-and two-way ANOVA, and Tukey honestly significant difference (HSD) multiple comparison tests. It was found that tea was more chromogenic than either filtered coffee or cola, and that acrylic teeth that had been immersed in tea for 4 weeks displayed the greatest colour change when compared to porcelain teeth. Tea is more chromogenic than filtered coffee and cola. The colour stability of porcelain teeth is greater than that of acrylic teeth. The degree of discolouration of acrylic and porcelain teeth after their immersion in tea, filtered coffee and cola is time dependent.
