- Tujuan penelitian ini adalah untuk mengetahui pengaruh jarak sumber sinar Light Emitting Diode (LED) terhadap kekuatan tarik diametral resin komposit bulk-fill. Resin komposit bulk-fill Tetric® N-Ceram Bulk-Fill, shade IVA (setara dengan warna VITA A2-A3) dibuat menjadi 30 spesimen berbentuk silinder dengan ukuran tebal 3 mm dan diameter 6 mm. Spesimen dibagi menjadi 3 kelompok variasi jarak penyinaran, yaitu 0 mm, 3 mm dan 5 mm. Penyinaran menggunakan LED Light Curing Unit Bluephase® Style (Ivoclar-Vivadent, Liechtenstein) dengan durasi penyinaran selama 10 detik sesuai instruksi pabrik. Data dianalisis secara statistik menggunakan metode ANOVA satu arah. Hasil analisis tidak menunjukkan perbedaan bermakna (p>0,05) pada semua kelompok. Jarak sumber sinar LED ≤ 5 mm tidak memberikan pengaruh yang signifikan terhadap kekuatan tarik diametral resin komposit bulk-fill <hr> This study aimed to evaluate the effect of LED light source distance on diametral tensile strength of bulk-fill composite restorative material. Bulk-fill composite Tetric® N-Ceram Bulk-Fill, shade IVA (equal to VITA shade A2-A3) was formed into 30 cylindrical specimens with 3 mm in thickness and 6 mm in diameter. Specimens were divided into 3 groups with various curing distance: 0 mm, 3 mm and 5 mm. All groups were polymerized by LED Light Curing Unit Bluephase® Style (Ivoclar-Vivadent, Liechtenstein) for 10 seconds based on manufacturer’s instruction. Data were statistically analyzed by one-way ANOVA The result showed insignificant differences in all groups (p>0,05). LED light source distance ≤ 5 mm was not significantly affected the diametral tensile strength of bulk-fill composite
