The purpose of this study was to investigate the color stability of flowable composite resins after immersion in a Coffee Mix and green tea solution with or without surface glazing resin.
Three flowable composite resins(Filtek Flow, Aeliteflo and DenFill Flow)and one universal hybrid composite resins(Z-100) were used for the specimens in this study. Eighty specimens(12mm¡¿2mm) were fabricated from each composites resin and were divided into two groups(mechanical polishing only; Unglazing group, and chemical polishing with surface glazing resin; Glazing group). Each group of specimens were immersed in a Coffee Mix solution and a green tea solution during 185 hours(about 8 days).
The color changes(¥ÄE*) of all specimens before and after staining were measured by Spectrophotometer(Minolta 3500d, Japan) and statistically analyzed.


The results were as follows:
1. All of the specimen groups showed perceivable and significant color change(¥ÄE*). Flowable resin groups showed different color changes according to the polishing methods, and discoloring solution. Among unglazing groups, DenFill Flow in a green tea solution showed the least color change(1.26¡¾0.75) and Filtek Flow in a Coffee Mix solution showed the greatest color change(9.04¡¾3.13). Hybrid resin Z-100 by unglazing in green tea solution showed the least color change(2.29¡¾0.40) and showed the greatest color change (9.10¡¾1.13) in coffee mix solution by glazing (P< .001).
2. There was a significant greater color change in glazing groups than unglazing groups(P< .001).
3. There was a significant color change difference by discoloring solution : Coffee Mix solution showed more color change than green tea solution(P< .001).
