Abstract

The most commonly used denture base material is heat cured acrylic resin. This material possesses chemical properties, such as color stability. Discoloration of the denture base can be caused by the use of disinfectant solution on daily basis. This is caused by the characteristic of acrylic resin which absorbs water over long contact times with solutions. The most common disinfectant solution used is chlorhexidine gluconate 0.2%. But, nowadays there are a lot of natural substances that could be used as alternatives to chemical substances such as roselle flower. This is a laboratory experimental study using cylinder shape sample with diameter of 50 ± 0.1mm and 0.5 ± 0.1 mm. The total of 60 samples is classified to 12 groups. The result shows significant result in discoloration with the usage of Chlorhexidine gluconate 0,2% in 1 year (92 hours), 2 years (183 hours), and 3 years (274 hours) with p=0.01 (p<0.05), p=0.001 (p<0.05), p=0.001 (p<0.05), and the roselle flower group in 3 years (183 hours) with p=0.021 (p<0.05). This study shows significant effect between time of usage to discoloration in acrylic resin groups that are soaked with the extract of roselle flower in 1 year (61 hours), 2 years (122 hours), and 3 years (183 hours) of contact with p = 0.025. Roselle's extract of 40% can be used as natural disinfectant solution of heat cured acrylic resin.
