Abstract

Latar belakang: Restorasi kelas V menyajikan tantangan bagi klinis karena tingginya risiko kebocoran mikro pada daerah servikal sekaligus adanya tuntutan estetika. Resin komposit single-shade merupakan material yang relatif baru di pasaran dan diklaim dapat menyamai semua warna gigi. Resin komposit bulk-fill diketahui menunjukkan stress penyusutan polimerisasi yang lebih rendah dan aplikasi yang lebih mudah. Tujuan: Mengetahui perbandingan kebocoran mikro resin komposit  single-shade dengan resin komposit bulk-fill pada restorasi kelas V. Metode: Penelitian eksperimental dengan sampel 20 gigi premolar rahang atas, dibagi menjadi dua kelompok (n=10), dan dipreparasi kavitas kelas V dengan ukuran 3x3x3 mm. Kelompok A ditumpat dengan resin komposit single-shade, kelompok B ditumpat dengan resin komposit bulk-fill. Sampel dimasukkan ke inkubator dengan suhu 37°C selama 24 jam, kemudian dilakukan proses thermocycling manual pada suhu 5°C dan 55°C sebanyak 100x. Gigi direndam dalam metilen biru selama 24 jam. Sampel dipotong dengan menggunakan separating disc dalam arah bukal ke palatal, dan kebocoran mikro diamati dengan stereomikroskop perbesaran 40x. Hasil: Nilai skor rata-rata kebocoran mikro resin komposit single-shade lebih tinggi dibandingkan resin komposit bulk-fill. Data dianalisis menggunakan uji Mann Whitney yang menunjukkan bahwa terdapat perbedaan yang signifikan antara kedua kelompok tersebut (p<0,05). Simpulan: Resin komposit single-shade memiliki kebocoran mikro yang lebih besar dibandingkan dengan resin komposit bulk-fill.

Abstract

The development of restorative materials presents a universal single-shade resin composite claimed to match all tooth colors. In addition to aesthetics, composite resin must have good mechanical properties. The temperature factor affects the polymerization, which will affect the compressive strength. The purpose of study was to investigate the effect of preheating on the compressive strength of single-shade universal resin composite. Universal single-shade resin composite was used to make cylindrical specimens with a diameter of 3 mm and a thickness of 6 mm and divided into two groups: with and without preheating (n=9). Specimens of preheating groups were prepared by heating the resin composite in a heater device at 600C for 15 minutes, then placed in the mold and irradiated using a light curing unit with an intensity of 2300 mW/cm for 6 seconds and then polished using composite polishing kits. The compressive strength was tested using a universal testing machine. The data obtained were analyzed using an independent t-test. The result of study showed the mean compressive strength values were significantly higher in the preheated group than in the non-preheated group (p0.05). The conclusion of this study was preheating universal single-shade resin composite to 60 degrees Celsius significantly enhances its compressive strength.
