Plat gigi tiruan resin akrilik yang berada dalam lingkungan mulut dapat menjadi tempat yang baik bagi akumulasi stain ekstrinsik yang merupakan perubahan warna di bagian luar plat akibat kontaminasi agen ekstrinsik. Stain ekstrinsik pada permukaan plat resin akrilik gigi tiruan dapat dilepaskan melalui tiga metode pembersihan yaitu mekanik, kimia, dan kimia dilanjutkan mekanik. Tujuan penelitian adalah untuk mengetahui perbedaan metode pembersihan gigi tiruan secara mekanik, kimia, dan kimia dilanjutkan mekanik terhadap pelepasan stain ekstrinsik teh hitam pada permukaan plat gigi tiruan resin akrilik kuring panas. Jenis penelitian adalah ekperimental laboratoris. Subjek penelitian berupa plat resin akrilik kuring panas ukuran 60x10x2 mm berjumlah 30 buah yang dibagi dalam 3 kelompok. Seluruh subjek direndam dalam larutan teh hitam 2% selama 14 hari lalu setiap kelompok dibersihkan dengan satu metode pembersihan yaitu mekanik, kimia, atau kimia dilanjutkan mekanik. Stain yang terlepas diukur menggunakan alat spektrofotomer UV-Vis Cintra 2000 berdasarkan nilai absorbansi subjek. Hasil penelitian menunjukkan terdapat perbedaan pelepasan stain ekstrinsik teh hitam yang bermakna (p<0,05) antara metode pembersihan mekanik, kimia, dan kimia dilanjutkan mekanik. Metode kimia dilanjutkan mekanik memiliki nilai perbedaan pelepasan stain ekstrinsik teh hitam yang signifikan (p<0,05) dengan metode kimia dan metode mekanik. Metode kimia dilanjutkan mekanik pembersihan gigi tiruan mampu melepaskan stain ekstrinsik teh hitam pada permukaan plat gigi tiruan resin akrilik kuring panas lebih banyak daripada metode mekanik dan metode kimia. Kata kunci : stain ekstrinsik, resin akrilik kuring panas, metode pembersihan gigi tiruan

Acrylic resin denture plate which is located in the oral environment can be a good spot for the extrinsic stain accumulation. Extrinsic stain is defined as discoloration located on the outer surface of the plate and is caused by extrinsic agents. The extrinsic stain on the surface of acrylic resin denture plate can be removed by three cleaning methods, which are mechanical, chemical and chemical followed by mechanical methods. The objective of the research is to determine the differences of denture cleaning methods mechanically, chemically, and chemical followed by mechanical toward the release of extrinsic stain of black tea on the surface of hot-cured acrylic resin denture plate. The type of the research is experimental laboratories. The subjects of the research are 30 hot-cured acrylic resin plates with the size of 60x10x2 mm, which are divided into 3 groups. The entire subject was immersed in a solution of 2% black tea for 14 days. Afterward, each group was cleaned up by using one of three cleaning methods. The released stain was measured by using the spectrophotometer UV- Vis Cintra 2000 based on the absorbance value of the subjects. The result of the research showed that there was significance difference (p<0.05) in the release of extrinsic stain of black tea among mechanical, chemical and chemical followed by mechanical cleaning method. Chemical followed by mechanical method showed a significant value (p<0.05) of the difference of extrinsic stain of black tea release than mechanical method and chemical method. The chemical followed by mechanical methods of denture cleaning is more effective to release the extrinsic stain of black tea on the surface of hot-cured acrylic resin denture plate than the mechanical method and chemical method. Keywords: extrinsic stain, hot-cured acrylic resin, denture cleaning methods
