“…[5][6][7] Resin komposit telah mengalami banyak perkembangan untuk meningkatkan sifatnya, salah satunya resin komposit nanofiller dengan tambahan teknologi nano dalam bahan pengisi komposit yang memiliki filler yang lebih kecil sebagai alternatif untuk mengatasi kekurangan yang dimiliki oleh jenis komposit lain. 5,[7][8][9] Resin ini memberikan pengerutan yang lebih rendah. 4,[10][11][12] Selain itu, resin ini dapat membentuk kontur yang baik dan digunakan sebagai restorasi pada gigi anterior maupun posterior, terlebih karies yang sering terjadi pada gigi posterior karena bentuk pit dan fissure yang dalam mengakibatkan makanan sering menumpuk.…”

“…Degradasi matriks ini akan menyebabkan menurunnya sifat resin komposit, salah satunya ialah kekerasannya. [8][9][10] Penelitian sebelumnya menggunakan larutan kopi robusta terhadap kekuatan tekan resin komposit nanofiller melaporkan adanya penurunan kekuatan, 26 namun penelitian dengan dua jenis kopi yang juga memiliki kandungan asam dan pH rendah terhadap kekerasan resin komposit nanofiller belum pernah dilaporkan. Berdasarkan latar belakang tersebut, maka penulis terdorong untuk meneliti apakah terdapat perbedaan pengaruh di antara kedua jenis kopi yaitu kopi robusta dan arabika terhadap kekerasan resin komposit nanofiller.…”

“…Degradasi pada ikatan siloksan ini menyebabkan filler terlepas dan terjadi penurunan kekerasan. 8 Pada penelitian ini digunakan resin komposit nanofiller Filtex TM Z350 XT dengan monomer matriks resin bersifat hidrofilik, sehingga nilai penyerapan dan kelarutan air yang tinggi memudahkan putusnya ikatan antara siloksan dan filler. 4,10 Filler yang terdapat pada resin ini merupakan kombinasi dari filler non aggregated silica dan zirconia di mana filler zirconia memiliki permukaan yang pori sehingga memudahkan proses terserapnya air dan terjadi penurunan resin komposit.…”

Nanofiller composite resin has small filler size which enhances its properties. However, these properties could decrease due to several factors. Acidic liquid such as coffee could reduce the hardness of composite resin. This study was aimed to analyze the effect of robusta and arabica coffee immersion on the hardness of nanofiller composite resin. A total of 27 composite resin samples were used and then were polished by using a soflex disc for 30 seconds on each roughness level. Samples were then divided into three groups, as follows: the control group with artificial saliva and the treatment groups with robusta coffee and arabica coffee. The composite resin molds were immersed in the three groups for 5 days. After five days of immersion, the hardness of the sample was tested by using a Vickers hardness tester. Artificial saliva as the control group had the highest mean hardness value of 112.98±8.67 VHN, followed by robusta coffee, and then by arabica coffee. The One Way Anova and post hoc LSD test showed that there were significant differences in all groups (p<0.05) except for the two treatment groups, namely robusta and arabica coffee groups which did not show any significant difference in the resin hardness (p>0.05). In conclusion, robusta and arabica coffee affect the hardness of the nanofiller composite resin, but there is no significant difference in the hardness between the robusta and arabica coffee groups.Keywords: composite resin hardness, nanofiller, robusta coffee, arabica coffee Abstrak: Resin komposit nanofiller memiliki ukuran filler kecil yang dapat meningkatkan fungsinya namun fungsi tersebut dapat menurun oleh beberapa hal. Cairan asam yang dikonsumsi seperti kopi dapat menurunkan kekerasan resin komposit. Penelitian ini bertujuan untuk mengetahui pengaruh perendaman kopi robusta dan arabika terhadap kekerasan resin komposit nanofiller. Sampel resin komposit yang digunakan sebanyak 27 buah dan dilanjutkan dengan pemolesan menggunakan soflex disc selama 30 detik setiap tingkat kekasarannya. Sampel kemudian dibagi dalam tiga kelompok, yaitu kelompok kontrol dengan saliva buatan dan dua kelompok perlakuan dengan kopi robusta dan arabika. Sebanyak 27 buah resin komposit direndam ke dalam tiga kelompok tersebut selama lima hari kemudian diuji kekerasannya dengan vickers hardness tester. Saliva buatan sebagai kelompok kontrol memiliki nilai rerata kekerasan tertinggi sebesar 112,98±8,67 VHN, diikuti kopi robusta, dan nilai terendah yaitu kopi arabika. Hasil uji One Way Anova dan post hoc LSD menunjukkan terdapat perbedaan bermakna pada semua kelompok (p<0,05) kecuali pada kedua kelompok perlakuan yaitu antara kopi robusta dan arabika tidak menunjukkan adanya perbedaan kekerasan yang bermakna (p>0,05). Simpulan penelitian ini ialah kopi robusta dan arabika memengaruhi kekerasan resin komposit nanofiller namun tidak terdapat perbedaan kekerasan antara keduanya.Kata kunci: kekerasan resin komposit, nanofiller, kopi robusta, kopi arabika

Acrylic resins are frequently used as the basic materials of dentures in daily dental practices. Submersion of dentures in disinfectant is usually done by denture users to prevent plaque accumulation. Red betel leaf decoction and essential oils of red betel leaf 10% and 25% can be used as an alternative natural disinfectant contain polyphenols, because it can inhibit the growth of Candida albicans which is commonly found in prosthesis denture users. On the other hand, the polyphenols of red betle leaves was predicted can affect the roughness and discoloration of acrylic resin. The purpose of this study was to determine the differences in surface roughness and discoloration of heat cured acrylic resin submersed in decoction of red betel leaf and essential oil of red betel leaf 10% and 25%. This study was a laboratory experimental with pre and post test group design research.measuring surface roughness value with surface roughness TR 220 and discoloration value with color reader TCR 200. Conclusion: there is a difference in surface roughness and discoloration of acrylic resin that is submersed in decoction of red betel leaves and essential oils of red betel leaf 10% and 25%.

“…Consequently, this affects the bond between the filler and the resin matrix causing it to become unstable. 19 Bonds are released and the material becomes porous. The release of this filler then causes numerous small gaps in the composite resin with the result that it becomes less dense, thereby reducing its mechanical properties, namely its hardness.…”

Background: Loss of tooth structure is a consideration in the performance of restorative treatment involving nanofilled composite resins. Material polymerization factors and water absorption can affect the hardness of composite resins. Imperfect polymerization producing an oxygen inhibited layer (OIL) and causing water absorption can even compromise the hardness of nanofilled composite resins. Tamarind soft drink, on the other hand, has an acidic pH that compromises the hardness of nanofilled composite resins. Purpose: This study aimed to reveal the effects of glycerin application on the hardness of nanofilled composite resins immersed in tamarind soft drinks. Methods: The research constituted a laboratory experiment using 24 nanofilled composite resin samples with diameters of 5mm or 2mm, divided into six groups, namely: Group G, Group G AS 60, Group G AS 120, Group TG, Group TG AS 60, and Group TG AS 120. Glycerin was applied to the surfaces of three groups before curing, while the other three groups were not treated with glycerin. Finishing was subsequently conducted on all samples using a highspeed handpiece and superfine finishing bur, before they were polished with a low speed handpiece. The samples were then divided into specific groups, namely: a group with a 120-minute immersion time, a group with a 60-minute immersion time, and a group which was not immersed and maintained at a temperature of 37 o C. Each sample was tested at three points using a Vickers hardness tester (VHT). Results: The results showed that the groups with glycerin had a higher hardness level than those groups. In addition, the non-immersed groups had a higher hardness level than those groups which were immersed. The one-way ANOVA test results confirmed that there was a statistically significant difference (p<0.05) between all groups. Conclusion: The application of glycerin to nanofilled composite resins immersed in tamarind soft drinks can increase their hardness levels.
