Preparation of Zinc Oxide Nanoparticles and its application in Dental Science

Abstract

Abstract: Zinc oxide can be called a multifunctional material which has high binding, antimicrobial, UV protection properties. These depend upon the size, shape and absorption peak. Zinc oxide nanoparticles are reported in attracting much attention due to their versatile and promising applications in biological sciences, such as antimicrobial, antifungal agent. Zinc oxide has the sealing ability for cavity filling, acting as cavity filler in the field of dentistry. Each of these factors were noteworthy in determining the properties of materials that lead to different dental applications. On the basis of above facts, we synthesized ZnO nanoparticles using ZnSO4 pellets with aqueous NaOH solution which will result in Zn(OH)2 and it was further decomposed to ZnO nanoparticles. The ZnO nanoparticles obtained were subjected for characterization using UV-Visible Spectroscopy, Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy and X-ray diffraction. The nanoparticles has a absorption peak of 379nm. FTIR showed bands from 2523cm-1 to 500cm-1 . The Scanning Electron Microscope revealed the nanoparticles to be in Spherical shape with size 96.3nm.The ZnO nanoparticles was subjected to antimicrobial activity using disc diffusion method with E.coli ATCC 25922, Klebsiella pneumonia, Streptococcus mutans MTCC 497, Lactobacillus acidophilus MTCC 10307 and Pseudomonas aeruginosa.These properties of nanoparticles will help in the application of dental science in preparing nanocavity filling material. As we synthesized molecules containing Zinc Oxide and subjected them for characterization, the strength and solubility tests are also determined for the obtained Zinc Oxide nanoparticles. The properties of nanoparticles will aid in the application for dentistry. Keywords: Cavity Filler; SEM; Olive oil; Zinc Oxide Nanoparticles; Dental Science
