Penelitian ini bertujuan untuk mengetahui pengaruh perendaman larutan nanas terhadap kekerasan permukaan resin komposit bulk-fill. Enam puluh spesimen resin komposit Tetric®N-Ceram Bulk-Fill shadeIVB berdiameter 6 mm dan tebal 3 mm dibagi menjadi dua kelompok perlakuan, yaitu perendaman dengan aquades sebagai kontrol dan larutan nanas pH: 3,8±0,1(n= 30). Sebelumnya seluruh kelompok direndam terlebih dahulu dalam aquades selama 24 jam dalam inkubator bersuhu 37oC sebagai baseline. Kemudian masing-masing kelompok tadi akan direndam kembali dalam larutan selama 1 hari, 3 hari dan 7 hari (n= 10). Kekerasan permukaan diukur menggunakan HMV-G SeriesVickers Micro Hardness Tester Shimadzu®dengan indenter Knoop. Setiap spesimen akan diindentasi dengan beban sebesar 50 gf, sebanyak 5 kali indentasi. Hasil penelitian menunjukkan bahwa terdapat perbedaan bermakna (p<0,05)antara perendaman 1 hari, 3 hari dan 7 hari pada kelompok perendaman larutan nanas dengan uji One-way ANOVA. Disimpulkan bahwa larutan nanas dapat menurunkan kekerasan permukaan resin komposit bulk-fill.
This study aims to determine effect of pineapple solution immersion on surface hardness of bulk-fill composite resin. Sixty specimens of Tetric®N-Ceram Bulk-Fill composite resin shade IVB, 6 mm in diameter and 3 mm thick were divided into two groups, with immersion in aquades as a control and pineapple solutionpH: 3,8±0,1 (n= 30). Before immersion, all specimens were immersed in aquades for 24 hours and were saved in incubator at 37oC as a baseline.Each group of immersions would be divided into three groups, with immersion for 1 day, 3 days and 7 days (n= 10). The surface hardness was measured using HMV-G Series Vickers Micro Hardness Tester Shimadzu®with Knoop Indenter. Each specimen was indented with load of 50 gf for 5 times. The results showed that there were statistically significant differences (p <0.05) between pineapple solution immersion for 1 day, 3 days and 7 days with One-way ANOVA test. It can be concluded that pineapple solution can reduce surface hardness of bulk-fill composite resin.
