PERBEDAAN TINGKAT KECEPATAN PERUBAHAN WARNA RESIN KOMPOSIT PACKABLE TERHADAP MINUMAN KOPI, TEH DAN SOFTDRINK (COLA)

Composite resin is diffusion so that it can absorb liquid in the mouth that can cause staining so can absorb fluids in the oral cavity that can cause staining. Of which form the content of coffee (tannins), tea (catechins), and cola (caramel). This study aimed to determine the rate of speed difference discoloration on packable composite resin to drink coffee, tea, and cola. Circular samples with a diameter of 20mm and 2mm thick, packable composite resin used was 3M ESPE 2250 FiltekTM totaling 16 samples are 4 soaked in distilled water (control), 4 soaked in coffee, tea soaked in 4, and 4 soaked in cola. Long soaking time performed for 1, 7 and 14 days with temperatures 37°C in the incubator. After soaking the samples was measured using a chromameter. In conclusion the results obtained, coffee and tea have different speed levels discoloration significant p<0.05, which tea caused more discoloration of speed than coffee in the packable composite resin. Unlike the cola that does not change significantly p>0.05 in the packable composite resin.
