Abstract

Resin komposit adalah bahan restorasi yang sering digunakan karena bersifat estetis tinggi. Filler anorganik seperti glass silica sebagai salah satu komposisi penting dalam resin komposit memiliki kelemahan berupa non-degradable, proses energinya tergantung pada bahan bakar fosil, serta emulsi polutannya tinggi dan membahayakan kesehatan dan lingkungan membuat filler alami sebagai bahan pengisi alternatif diperlukan. Salah satu serat alami yang dapat digunakan adalah serat sisal (Agave sisalana). Penelitian ini bertujuan untuk mengetahui perbedaan kekuatan geser antara semen resin komposit nanosisal 60% Wt dan semen resin nanofiller komposit. Penelitian ini merupakan penelitian eksperimental laboratoris. Serat sisal selanjutnya diubah menjadi ukuran nano. Nanosisal dicampur dengan Bis-GMA, UDMA, TEGDMA, dan Champhorquinone. Semen resin nanofiller komposit (AllCem Core) sebagai kontrol. Sampel berjumlah 10 dibagi menjadi dua kelompok. Gigi premolar dipreparasi tumpatan kelas V lalu ditumpat menggunakan dua bahan tersebut. Kekuatan geser sampl diuji menggunakan Universal Testing Machine (UTM). Analisis data menggunakan uji Independent Sample T-Test. Hasil menunjukkan semen resin nanosisal komposit 60% memiliki rata-rata kekuatan geser 13,10  MPa, dan semen resin nanofiller komposit 4,92 MPa. Analisis data menunjukkan perbedaan yang signifikan (p=0,000). Kekuatan geser semen resin nanosisal komposit 60% lebih besar dibandingkan dengan semen resin nanofiller komposit.

Abstract

Composite resin has three main components: a resin matrix, filler particles (filler), and a coupling agent. The inorganic nature of composite resin filler particles contrasts with the organic components prevalent in tooth structure and some adhesives. Therefore, to increase adhesive, innovative composite materials containing organic fillers are required. The aim is to describe the effect of curing time (20, 30, and 40 seconds) on the microscopic adhesion strength of composite resins containing (a) nano sisal, (b) silane-treated hydroxyapatite nano sisal, and (c) Z350XT nanofiller (control) to dentin. This descriptive study investigated the potential of nano sisal, a sisal fiber-based filler in composite resin, as an alternative to conventional synthetic fillers. Samples were divided into three groups: nano sisal composite (Group A), nano sisal composite with a coupling agent (Group B), and Z350XT nanofiller composite (Group C). Premolar teeth were filled with all three composite groups and cured for 20, 30, and 40 seconds. Standardized samples were then extracted for microscopic adhesion observation via a Scanning Electron Microscope (SEM). SEM images of groups A, B, and C showed a gap in the adhesion between the composite resin and the tooth structure. The smallest adhesion distance in group A was at a curing time of 20 seconds (0.687 μm). Group B had a large adhesion distance at 20 seconds (15.747 μm). The smallest microleakege in group C was at 40 seconds of curing time. It was 0.644 μm. Microscopic examination using SEM reveals the presence of microscopic defects at the interface between the restoration and the tooth structure across all investigated curing times (20, 30, and 40 seconds).

Abstract

Background: Dental composite composed of natural filler is a trend nowadays. Silk fiber, Bombyx mori L., is one of the natural fibers that have good microhardness (66 VHN) and has a potency to become a renewable natural filler. This research aimed to determine microhardness differences of silk fiber composite B. mori L., and nanofiller composite resin as a gold standard.Method: A quasi-experimental laboratory using composite resin with silk fiber B. mori L., as a natural filler; nanofiller composite Z350 XT flowable (3M ESPE, USA) as a positive control and no-filler composite as a negative control. Four cylindrical specimens per group were made (d=3mm, h=6mm). Microhardness tests were done with Vickers hardness tester (Shimadzu, Japan). Indentation of 100 grams for 20 seconds.Result: There were significant differences in the natural filler, nanofiller group (positive) control and no-filler composite (negative control). Based on the Kruskal Wallis test result, there was a significant difference in microhardness (p=0.024). The highest microhardness was nanofiller (115,2 VHN), silk fiber filler (109,4 VHN), and no-filler composite (32,2 VHN).Conclusion: Silk fiber Bombyx mori L., has shown the good potential of being a renewable natural filler (109,4 VHN) however lower than nanofiller composites.
