Long immersion type heat cured acrylic resin in 10% chocolate drinks for 4 days, 8 days, 12 days, and 16 days of immersion. Change the color of acrylic resin caused by soaking in a chocolate beverage was measured using computer software programs grayscale image that will produce an image / pattern recognition in image form HBS (Hue, Brightness, Saturation), which in this study using image HBS. However, in this study uses the results of brightness that can show the brightness.. Result. The result was analyzed the results using independent sample T-test at 5% significance level to determine if there are differences in color changes in acrylic resin using a computer statistical software program SPSS Version 16.0 for Windows to find out more about the differences that exist among the groups.
