"Latar Belakang: Resin komposit merupakan bahan restorasi yang telah dikembangkan komposisinya sehingga memiliki sifat estetika, fisik, dan mekanik yang lebih baik dan diharapkan dapat mengatasi masalah yang disebabkan oleh material restorasi lainnya. Resin komposit PALFIQUE® Universal Flow dari Tokuyama Dental merupakan resin komposit yang telah dikembangkan partikel filler-nya dan diklaim memiliki kemampuan pemolesan yang tinggi serta estetika yang sempurna. Salah satu sifat permukaan restorasi resin komposit, surface gloss, memegang peranan penting terhadap estetika restorasi. Surface gloss dipengaruhi oleh berbagai faktor intrinsik dan ekstrinsik dan diantara faktor ekstrinsik yaitu sistem pemolesan. Tujuan: Menganalisis pengaruh sistem pemolesan terhadap surface gloss resin komposit supra-nano PALFIQUE® Universal Flow tipe Super Low dan Medium. Metode: Empat puluh delapan spesimen resin komposit supranano PALFIQUE® Universal Flow berbentuk silinder berdiameter 6 mm dan tinggi 2 mm dibuat untuk penelitian ini. Spesimen dibagi menjadi 6 kelompok berdasarkan tipe resin komposit (Super Low dan Medium) dan sistem pemolesan (Sof-LexTM Spiral, Sof- LexTM XT Polishing Discs, Tanpa Pemolesan). Penyinaran resin komposit dilakukan dengan light curing unit iradiansi 1050 mW/cm2 selama 12 detik. Setiap spesimen dilakukan pengujian surface gloss dengan glossmeter sebanyak tiga kali. Data dianalisis menggunakan uji statistik One-Way ANOVA dan Independent Sample T-Test. Hasil: Nilai surface gloss semua kelompok berada pada rentang 76–96 GU. Surface gloss tertinggi dimiliki oleh kelompok tanpa pemolesan. Sistem pemolesan Sof-LexTM XT Polishing Discs menghasilkan surface gloss lebih tinggi dibandingkan Sof-LexTM Spiral dengan perbedaan yang signifikan (p<0,05). Surface gloss resin komposit tipe Super Low lebih tinggi dibandingkan tipe Medium dengan perbedaan yang signifikan (p<0,01). Kesimpulan: Surface gloss turut dipengaruhi oleh tipe resin komposit dan sistem pemolesan.

Background: Composite resin is a restorative material with composition that has been developed so that it has better aesthetic, physical, and mechanical properties and is expected to overcome problems caused by other restorative materials. PALFIQUE® Universal Flow composite resin from Tokuyama Dental is a composite resin with developed filler particles and is claimed to have high polishing ability and perfect aesthetics. One of the surface properties of composite resin restorations, surface gloss, plays an important role in the aesthetics of the restoration. Surface gloss is influenced by various intrinsic and extrinsic factors and among the extrinsic factors is the polishing system. Objectives: The aim of this study was to analyze the influence of different polishing systems on surface gloss of Super Low and Medium PALFIQUE® Universal Flow composite resin. Materials and Methods: Forty-eight specimens of PALFIQUE® Universal Flow supra-nano composite resin in cylindrical shape (diameter of 6 mm and height 2 mm) were used in this study. The specimens were divided into six groups by type (Super Low and Medium) and by polishing systems (Sof-LexTM Spiral, Sof-LexTM XT Polishing Discs, mylar strip). Specimens were polymerized with light curing unit for 12 seconds with light irradiance of 1050 mW/cm2. Each specimen was tested for surface gloss with a glossmeter three times. Data then were analyzed with One-Way ANOVA and Independent Sample T-Test. Results: Surface gloss value of all groups were above the clinically acceptable threshold (76–96 GU). Highest surface gloss value was shown on the mylar strip group. Higher surface gloss values were produced by Sof-LexTM XT Polishing Discs compared to Sof-LexTM Spiral, statistically significant (p<0,05). Surface gloss values were significantly higher on type Super Low compared to Medium (p<0,01). Conclusion: In this study, surface gloss value was influenced both by the type of composite resin and differences in polishing systems."

"ABSTRACTTujuan: Penelitian ini bertujuan untuk mengetahui pengaruh sistem pemolesan terhadap perubahan warna resin komposit mikrohibrida setelah perendaman dalam larutan Luwakwhite coffee. Material dan Metode Penelitian: Dalam penelitian ini digunakan empat puluh dua spesimen berdiameter 6 mm dan tebal 2 mm yang dibagi menjadi 6 kelompok dengan 2 bahan yang berbeda yaitu G-aenial PosteriorTM dan Filtek Z250TM dipoles menggunakan Sof-Lex disc SuperfineTM, PoGo, dan tidak dipoles. Spesimen di polimerisasi menggunakan LED Curing Unit dengan irradiansi 700 mW/cm2 (LED Max Hilux) selama 20 detik. Setelah dipoles, spesimen direndam dalam larutan Luwak white coffee selama 7 hari. Perubahan warna diukur menggunakan colorimeter NH310 (Shenzhen 3NH) dengan sistem warna CIE Lab. Data dianalisis menggunakan uji Statistik One-Way Anova Test. Hasil: Setelah dipoles, terdapat perbedaan yang signifikan (p<0,05) pada nilai I E1 dan nilai I a1, namun untuk nilai I L1 dan nilai I b1 tidak terdapat perbedaan yang signifikan. Setelah perendaman dalam larutan Luwakwhite coffee, terdapat perbedaan yang signifikan (p<0,05) pada nilai I E2, nilai I b2. Sedangkan, nilai I L2 hampir terdapat perbedaan yang signifikan pada seluruh kelompok, kecuali G-aenial PosteriorTM yang tidak dipoles dengan Filtek Z250TM yang tidak dipoles, Filtek Z250TM yang tidak dipoles dengan Filtek Z250TM yang dipoles menggunakan Sof-LexTM Superfine, dan G-aenial PosteriorTM yang dipoles menggunakan Sof-LexTM Superfine dengan Filtek Z250TM yang dipoles menggunakan Sof-LexTMSuperfine serta nilai I a2 hampir terdapat perbedaan yang signifikan pada seluruh kelompok, kecuali Filtek Z250TM yang tidak dipoles dengan Filtek Z250TM yang dipoles menggunakan PoGo. Kesimpulan: Sistem pemolesan yang berbeda dapat mempengaruhi nilai perubahan warna resin komposit mikrohibrida. Pemolesan menggunakan PoGo menghasilkan perubahan warna paling kecil. Filtek Z250TM memiliki perubahan warna terkecil setelah perendaman dalam larutan Luwak white coffeeselama 7 hari.

ABSTRACTObjectives: This study aims to analyze the influence of polishing systems on color change of microhybrid composite resin after immersion in Luwak white coffee solution.Material and Methods: In this study, fourty two specimens, 6 mm in diameter and 2 mm thick, were divided into six groups with different composite types, that is G-aenial PosteriorTM and Filtek Z250TM, polished with Sof-Lex disc SuperfineTM, PoGo and unpolished. The specimens are polymerized for 20 seconds using a 700 mW/cm2irradiance LED curing unit (LED Max Hilux). After polishing, the specimens are immersed in Luwak white coffee solution for 7 days. The color change is measured using a colorimeter NH310 (Shenzhen 3NH) with the CIE Lab color system. Data were analyzed using One-Way ANOVA test. Results: After polishing, there were statistically significant differences (p<0,05) between the I E1 and I a1 groups. However, statistically significant differences were not found between the I L1 and I b1 groups. After immersed in Luwak white coffee, there were statistically significant differences (p<0,05) between the I E22 and I b1 groups. Meanwhile, almost all of the I L2 groups showed a significant increase, except for G-aenial PosteriorTM unpolished with Filtek Z250TM unpolished, Filtek Z250TM unpolished with Filtek Z250TM polished using Sof-LexTMSuperfine, G-aenial PosteriorTM polished using Sof-LexTM Superfine with Filtek Z250TMpolished using Sof-LexTM Superfine and I a2 groups showed a significant increase, except Filtek Z250TM unpolished with Filtek Z250TM polished using PoGo. Conclusions:It was concluded that different polishing systems affect color change of the microhybrid composite resins. Polishing with PoGo produces the smallest color change. Filtek Z250TM was determined to have the smallest color change after immersion in Luwak white coffee for 7 days."
