Latar Belakang: Dalam dunia kedokteran gigi, terdapat banyak pilihan material restoratif yang dapat digunakan, salah satunya yaitu resin komposit. Seiring dengan perkembangan teknologi, para peneliti berhasil mengembangakan resin komposit baru yaitu Bulk-Fill. Sebagai contoh adalah resin komposit Giomer Bulk-Fill yang memiliki berbagai sifat seperti sifat mekanik, fisis dan biologis. Namun, belum ada penelitian pada resin komposit Giomer Bulk-Fill yang secara spesifik menguji nilai kekuatan tarik diametral yang merupakan salah satu sifat mekanik material restoratif. Tujuan Penelitian: Penelitian ini bertujuan untuk mengetahui pengaruh lama perendaman 1, 24, dan 72 jam serta perbedaan nilai pH saliva buatan 7; 5,5; dan 4,5 terhadap kekuatan tarik diametral resin komposit Giomer Bulk-Fill. Metode: Penelitian eksperimental laboratorik dengan menggunakan 90 spesimen berbentuk silindris pejal dengan diameter 6 mm dan tinggi 3 mm yang diuji menggunakan Universal Testing Machine (Shimadzu AGS-X 5kN, Japan) dan dibagi ke dalam 3 kelompok pH larutan saliva buatan yaitu 7; 5,5; dan 4,5; serta 3 kelompok lama perendaman yaitu 1, 24, dan 72 jam. Hasil: Hasil pengujian menggunakan uji One-way ANOVA menunjukkan adanya perbedaan bermakna pada spesimen-spesimen yang digunakan (p<0,05). Pada kelompok spesimen yang direndam dalam larutan saliva buatan dengan pH 7, hasil rerata kekuatan tarik diametral pada perendaman selama 1 jam adalah sebesar 36,7 ± 2,7 MPa. Kemudian mengalami penurunan setelah perendaman 24 jam dengan rerata nilai kekuatan tarik diametralnya sebesar 35,2 ± 2,2 MPa dan meningkat kembali setelah perendaman 72 jam dengan hasil rerata kekuatan tarik diametralnya sebesar 40,1 ± 3,6 MPa. Pada kelompok spesimen yang direndam dalam larutan saliva buatan dengan pH 4,5, pada perendaman selama 1 jam hasil rerata kekuatan tarik diametralnya sebesar 33,6 ± 2,4 MPa. Kemudian setelah perendaman 24 jam dan 72 jam meningkat menjadi 42,6 ± 2 MPa dan 44,2 ± 2,8 MPa. Pada kelompok spesimen yang direndam dalam larutan saliva buatan dengan pH 5,5, hasil rerata kekuatan tarik diametral setelah perendaman selama 1 jam adalah sebesar 34 ± 2,4 MPa. Namun, terjadi perbedaan jika dibandingkan dengan kelompok pH 4,5 yaitu pada kelompok dengan pH 5,5 pada lama perendaman 24 jam terjadi peningkatan yaitu sebesar 44,7 ± 2,8 MPa kemudian menurun setelah perendaman 72 jam dengan nilai rerata sebesar 39 ± 3,3 MPa. Kesimpulan: Nilai kekuatan tarik diametral resin komposit Giomer Bulk-Fill tidak dipengaruhi oleh pH saliva buatan 4,5; 5,5; dan 7 yang digunakan di dalam penelitian ini. Nilai kekuatan tarik diametral resin komposit Giomer Bulk-Fill yang direndam selama 1, 24, dan 72 jam di dalam saliva buatan dengan pH 4,5; 5,5; dan 7 secara umum mengalami peningkatan sehingga lama perendaman dalam penelitian ini mempengaruhi nilai kekuatan tarik diametral resin komposit Giomer Bulk-Fill.
Background: In the world of dentistry, there are many choices of restorative materials that can be used, one of them is composite resin. Along with the development of technology, the researchers succeeded in developing a new composite resin called Bulk-Fill. One example is Giomer Bulk-Fill composite resin which has various properties such as mechanical, physical and biological properties. However, there is no research on Giomer Bulk-Fill composite resin which specifically tests the value of diametral tensile strength which is one of the mechanical properties of restorative material. Objective: This study aims to determine the effect of immersion time and the difference in pH value 7; 5,5; and 4,5 of the artificial saliva solution on the value of diametral tensile strength of Giomer Bulk-Fill composite resin. Method: Laboratory experimental research using 90 solid cylindrical specimens with a diameter of 6 mm and a height of 3 mm which were tested using Universal Testing Machine (Shimadzu AGS-X 5kN, Japan) and were divided into 3 groups pH of artificial saliva solution (7; 5.5; and 4.5) and 3 groups of immersion periods (1, 24 and 72 hours). Results: The test results using the One-way ANOVA test showed significant differences in the specimens used (p <0.05). In the group of specimens which were immersed in artificial saliva solution with pH 7, the results of the average diametral tensile strength at immersion for 1 hour were 36.7 ± 2.7 MPa. Then it decreased for 24 hours immersed time with a mean value of diametral tensile strength of 35.2 ± 2.2 and increased again at 72 hours immersed time with an average value of diametral tensile strength 40.1 ± 3.6 MPa. In the group of specimens which were immersed in artificial saliva solution with pH 4.5, at immersion for 1 hour the average value of diametral tensile strength was 33.6 ± 2.4 MPa. Then in 24-hour and 72-hour immersion, it increased to 42.6 ± 2 MPa and 44.2 ± 2.8 MPa. In the group of specimens immersed in artificial saliva solution with a pH of 5.5, the average value of diametral tensile strength for 1 hour was 34 ± 2.4 MPa. However, there was a difference when compared to the pH 4.5 group, which was in the group with a pH of 5.5 in the 24-hour immersion period, the value increase for 44.7 ± 2.8 MPa and then decreased for 72 hours of immersion with an average value of 39 ± 3.3 MPa. Conclusion: The value of diametral tensile strength of Giomer Bulk-Fill composite resin is not affected by pH of artificial saliva 4.5; 5.5; and 7 that used in this study. The value of diametral tensile strength of Giomer Bulk-Fill composite resin, which is immersed for 1, 24, and 72 hours in artificial saliva with pH 4.5; 5.5 and 7 generally increased so that the immersion time in this study affected the diametral tensile strength of Giomer Bulk-Fill composite resin.

Data yang diperoleh dianalisis secara statistik dengan tes Kruskal Wallis dan Mann Whitney. Hasil: Analisis sembilan sampel dari masing-masing grup menunjukkan bahwa peningkatan shear bond strength yang paling banyak terjadi pada Grup 3 (56,04±11,06MPa) dibanding dengan Grup 2 (29,09±7,63MPa) dan Grup 1 (25,55±2,22MPa) dan perbedaannya bermakna secara statistik (p<0,05). Simpulan: Aplikasi asam askorbat 10% pada dentin pasca pemutihan gigi interna dengan gel H2O2 35% dapat meningkatkan shear bond strength resin komposit.
Restoration of the teeth immediately after bleaching with H2O2 35% is contraindicated due to the remnants of free radical that will stay inside dentin for 2-3 weeks which will compromise the adhesiveness of composite resin. Objective: The aim of this study was to evaluate the influence of 10% ascorbic acid on shear bond strength of composite placed on bleached dentin. Methods: Twenty seven samples were divided equally into three groups. Group 1: dentin was etched with 35% phosphoric acid; Group 2: dentin was bleached with 35% H2O2 followed by etching with 35% phosphoric acid; Group 3: dentin was bleached with 35% H2O2, followed by application of 10% ascorbic acid and etched with 35% phosphoric acid. All samples were then stored at 370 C for 24 hours. The Universal Testing Machine was used to measure shear bond strength and the results were analyzed with Kruskal Wallis and Mann Whitney test. Results: After nine independent experiments, 10% ascorbic acid application on bleached dentin resulted in highest increased in bond stregth (56.04±11.06MPa) compared to Group 2 (29.09±7.63MPa) and Group 1 (25.55±2.22MPa) and the difference was statistically significant (p<0.05). Conclusion: Application of 10% ascorbic acid to the bleached dentin improved the shear bond strength of resin composite.

Objectives. The aim of this study was to compare the fracture toughness of a microhybrid and a flowable microhyrid resin composites. Methods. Test specimens (30x15x2)mm made of a microhybrid and a flowable microhybrid were prepared in a double torsion mould and were then polymerized for 20 seconds using a light-curing device. Taken out from the mould, the specimens were than soaked in disfilled water (37°C) for 1 hour and then fractured in a double-torsion technique. t-Test was used to test significance difference between the microhybrid and flowable microhybrid resin composites. Result. The use of double-torsion technique resulted in crack initition and crack arrest which revealed Klc of 1.14 MN/m3/2 and 1.045 MN/m3/2 for the microhybrid and the flowable microhybrid resin composites, respectively. Both resin composites were insignificantly different in the fracture toughness values showed by t–Test. Conclusions. The present study suggested that there was no significant difference between the microhybrid and the flowable microhybrid resin composites tested. It appreared that filler fraction might not affect the fracture toughness of the resin composties tested.

Single-step self-etch adhesive systems are the system that combine self etching primer and bonding agent into one step application. This system was developed as the effort to simplified in application prosedures and give a good bond strength of resin composites to dentin surface. The purpose of this study was to examine the bond strength of resin composites with two singlestep self-etch adhesives system (Xeno III and Clearfil Tri-S Bond) to bovine dentin at temperature of adhesive 3ºC, 22ºC and 30ºC. Adhesive was applied to dentin surface (bovine insisivus mandibular dentin) follow by resin composites bonded according to the manufacturer’s instructions. Tensile bond strength of 60 specimens were tested UTM (universal testing machine) after 24 hours storage in aquadest at 37 ºC. The results were analyzed using ANOVA test followed by Tukey’s test (p< 0,05). The bond strength of Xeno III was significantly diffrent from that of Clearfil tri-S Bond, 0,66±0,271, 2,70±1,528, 0,23±0,104 versus 2,07±0,272, 4,77±0,689, 4,39±1,205 MPa at temperature of materials 3ºC, 22ºC and 30ºC respectively. The bond strength of two single- step adhesives system (Xeno III and Clearfil Tri-S Bond) were highest at temperature 22ºC than other temperatures of materials.

The use of resin composites as posterior restoratives has markedly increased over the past decade. The patients demand for better esthetics, concerns related to possible mercury toxicity from amalgam and improvements in resin composite materials have significantly contributed the popularity of these materials. Early problems related to composites included excessive wear, less of anatomic form, post operative sensitivity, secondary caries and marginal leakage. Marginal adaptation still remains an unavoidable problem for composite restoration, especially at the gingival wall of cervical or Class II restoration. In an attempt to improve marginal sealing, many techniques and lining materials have been designed. To reduce stress generated by polymerization shrinkage, applying and curing of resin composites in layers is often recommended. Using a thick adhesive layer or a low-viscosity resin may, due to its elastic properties, serve as a flexible intermediate layer and compensate for the polymerization stress created in resin composite. Flowable composites were created by retaining the same small practicle size of traditional hybrid composite but reducing the filler content and allowing the increased resin to reduce the viscosity of the mixture. Flowable composites were introduced in 1996 as liners, fissure sealants and also in tunnel preparations. They have been suggested for Class I, II, III and V cavity restorations, preventive resin restorations and composite, porcelain and amalgam repairing. Their usage as a liner under high filled resins in posterior restorations has been shown to improve the adaptation of composites and effectively achieve clinically acceptable results. This article attempts to give a broad characteristics of different types of flowable composites.
