Abstract

AbstractHeat cured acrylic resin is material that mostly used as a denture base. Cinnamon extract contains polyphenol which will make rough on the surface if it contact with acrylic resin. Aim of this research was to derermined the effect of cinnamon (Cinnamomum burmanii) extract concentration to surface roughness of heat cured acrylic resin. This research used 30 heat cured acrylic resin as specimens in size 20x20x2mm, 10 specimens for each concentrations of 40%, 50% and 60%. The specimens were immersed in aquades for 24 hours and tested the first surface roughness, and immersed in cinnamon extract with a concentration of 40%, 50% and 60% for 4 days. Each specimens tested the second roughness by using Surface Roughness Tester. Data was analyzed by paired t-test and one way ANOVA. Result showed a significant differences (p0,05) between the roughness before and after immersed in cinnamon extract concentrations of 40%, 50% and 60%. There was  a significant differences (p0,05) between the concentration of 40% and 50% to the concentration of 60%, and no significant differences between the concentration of 40% and 50%. Concluded that the surface roughness of heat cured acrylic resin increases with increasing of cinnamon (Cinnamomum burmanii) extract concentration.Keyword: heat cured acrylic resin, cinnamon extract, surface roughness

Abstract

Gigi tiruan yang sering digunakan adalah gigi tiruan resin akrilik. Saat ini telah berkembang pembersih gigi tiruan yang alami, salah satunya daun sirih (Piper betle Linn). Daun sirih diketahui berkhasiat sebagai antiseptik dan desinfektan. Penelitian ini bertujuan untuk mengetahui pengaruh perendaman elemen gigi tiruan resin akrilik dalam larutan daun sirih (Piper betle Linn) terhadap perubahan warna. Data hasil penelitian didapatkan bahwa tidak terdapat perubahan nilai hue, tetapi terdapat perubahan nilai value dan chroma. Hasil pengukuran value dan chroma dianalisis menggunakan uji non-parametrik Mann-Whitney (p0,05) untuk mengetahui adanya pengaruh perendaman larutan daun sirih (Piper betle Linn) terhadap perubahan warna, didapatkan nilai signifikansi p0,05 yang menunjukkan adanya pengaruh perendaman larutan daun sirih (Piper betle Linn) terhadap nilai value dan chroma pada elemen gigi tiruan resin akrilik. Hasil analisis data tersebut menunjukkan bahwa perendaman larutan daun sirih (Piper betle Linn) mempengaruhi perubahan warna elemen gigi tiruan resin akrilik.
