Effect of Duration of Heat Cured Acrylic Resin Platives in Granule Dental Cleaning Materials Effervescent Effect of Cocoa Pod(Theobroma C) 6,5 % Little Extracts on Color Stability

Objective: To determine the effect of duration of heat cured acrylic resin plates in granule dental cleaning material effervescent effect of cocoa pod(Theobroma Cacao L) 6,5% little extracts on color stability. Materials and Method: The reasearch methode use was True experimental laboratory pretest-posttest only with control group research design. Results: the results of the effect of duration immersion of the L value where the time of immersion was 10 minutes, 15 minutes, and 20 minutes the p-value was 0.768. The results of the effect of duration immersion of the A value where the duration immersion was 10 minutes, 15 minutes, and 20 minutes the p-value was 0.117. The results of the effect of duration immersion of the B value where the time of immersion was 10 minutes, 15 minutes, and 20 minutes the p-value was 0.173. The results of comparison of duration immerson of heat cured acrylic resin plates before and after immersion of the effervescent granule extract of cocoa peels (Theobroma Cacao L) based on the CIE LAB value where the time of immersion is 10 minutes, 15 minutes and 20 minutes p-value 0.325. Conclusion: No influence and does not appear to significantly influence color stability. This shows the effectiveness of stable color absorption as a denture cleaning ingredients.
