Abstract

The purpose of this study was to investigate the color change of denture base resins by coffee. Denture base resins for this study were Triad VLG Denture Base (Dentsply, York Div. U. S. A), Premium Super-20(Lang Dental Mfg. Co., Inc, U. S. A.) for denture base. Toughron Rebase (Miki Chemical Prod. Kyoto, Japan), Jet Repair Acrylic (Lang Dental Mfg. Co., Inc., U. S. A.), Triad Reline (Dentsply, York Div. U.S.A) and Tokuso Rebase (Tokuyama Soda Co., Japan) for denture rebase. Twenty specimens of each denture base resin were made and polished. The color of specimens was measured by colorimeter (Model Tc-6FX, Tokyo Denshoku Co. Japan), and they were stored in coffee for the weeks and then color changes were measured. @ES The obtained results were as follows: @EN 1. The L*, a*, b* and the E* ab values of all denture base resins were changed after three weeks. 2. The amount of color change on L*, a*, b* and the E* ab value of each specimens showed different patterns. 3. The b* values of Triad Reline materials were changed more than the other materials. 4. The E* ab values of Triad Denture Base materials were changed more than the other materials.
