SINTESIS DAN KARAKTERISASI SEMEN GIGI BERBASIS NANOPARTIKEL ZINC OXIDE

Abstract

SINTESIS DAN KARAKTERISASI SEMEN GIGI BERBASIS NANOPARTIKELZINC OXIDE. Semen gigi berbasis campuran Zinc Oxide (ZnO) dan eugenol merupakan salah satu semen gigi yang sering digunakan. Salah satu kekurangan utama yang membatasi aplikasinya adalah semen gigi ZnO dan eugenol memiliki sifat mekanik yang kurang begitu baik. Penelitian ini bertujuan melakukan sintesis dan karakterisasi semen gigi berbasis nano semen oksida dicampur dengan eugenol dengan hipotesis bahwa nanopartikel ZnO akan memberikan sifat mekanis yang lebih baik. Sifat fisis dan mekanis semen gigi berbasis nanopartikel semen oksida tersebut akan dibandingkan dengan semen gigi mikropartikel ZnO. Pencampuran eugenol dan nanopartikel ZnO dilakukan dengan komposisi bubuk 0,4 g, 0,45 g, 0,5 g, 0,55 g, 0,6 g dan cairan 0,2 mL. Nanopartikel ZnO sebagai bubuk dicampur dengan cairan sedikit demi sedikit, sehingga menghasilkan pasta. Metode analisis meliputi kekuatan tekan dan kekerasan, dan observasi strukturmikro. Dari serangkaian penelitian dan analisis diperoleh bahwa morfologi permukaan sampel semen gigi yang berbahan dasar nanopartikel lebih halus dan memiliki sedikit patahan dibandingkan dengan semen gigi berbahan dasar mikropartikel. Begitu juga analisis mekanik nanopartikel ZnO semen gigi dapat meningkatkan kuat tekan dan kekerasan dari bahan tersebut. Hasilnya diperoleh bahwa penambahan nanopartikel dapat meningkatkan karakteristik sifat fisis dan mekanis.

ABSTRACT

SYNTHESIS AND CHARACTERIZATION OF ZINC OXIDE NANOPARTICLES-BASED DENTAL CEMENT. Dental cement-based mixture of zinc oxide and eugenol is one of the commonly used dental cement. One of the major shortcomings that limit its application is dental cement zinc oxide and eugenol has detrimental mechanical properties. This study aims to carry out the synthesis and characterization of nano-based dental cement of zinc oxide mixed with eugenol with the hypothesis that zinc oxide nanoparticles will provide better mechanical properties. Physical and mechanical properties of cement-based dental cement oxide nanoparticles will be compared with dental cement zinc oxide microparticles. Mixing eugenol and ZnO nanoparticles were made by the composition of the powder 0.4 g, 0.45 g, 0.5 g, 0.55 g, 0.6 g and 0.2 mL of fluid.
ZnO nanoparticles as a powder slowly mixed with liquid, so as to produce pasta. Methods of analysis include compressive strength, hardness and microstructure observation. From a series of studies and analysis, the surface morphology of the samples obtained by the nanoparticles-based dental cement is smoother and has a little fracture compared with microparticles-based dental cement. Likewise, the mechanical analysis of dental cement, ZnO nanoparticles can increase the compressive strength and hardness of the material. The conclusions are that the addition of nanoparticles can enhance physical and mechanical characteristics. .
