An Evaluation and Comparison of Composition and Surface Characteristics of Different Orthodontic Wires – Energy Dispersing Spectrometry and SEM Study
Journal Title: INTERNATIONAL JOURNAL OF RECENT TRENDS IN SCIENCE AND TECHNOLOGY - Year 2014, Vol 10, Issue 2
Abstract
Aim: To evaluate and to understand the composition and surface characteristics of different orthodontic wires. Materials and method: Six different orthodontic wires 1) stainless steel wires, 2)TMA wires 3) low friction TMA wires, 4) colored low friction TMA wires aqua, 5) colored low friction TMA wires purple, 6) colored low friction TMA wires honey dew were evaluated in this study. Surface characteristics of the orthodontic wires before and after the sliding process were evaluated using SCANNING ELECTRON MICROSCOPE (SEM). Composition of orthodontic wires was evaluated using ENERGY DISPERSING SPECTROMETRY (EDS). Results: SEM study clearly illustrates the variation in surface roughness of all the orthodontic wires. Untreated TMA wires exhibit the maximum surface roughness before and after sliding. Colored low friction TMA exhibit relatively smooth surface before and after sliding, with honey dew variety of TMA exhibiting the least noticeable change. Elemental analysis by EDS reveals the presence of oxygen in low friction colored TMA wires. Conclusion: The surface roughness is highest in TMA and the surface roughness is lowest in colored low friction TMA honeydew
