Abstract

Introduction: The surface roughness of orthodontic arch wires is an important factor as it influences corrosion, friction, tooth movement, biocompatibility, aesthetics and hygiene. The purpose of this study was to evaluate the surface roughness of seven groups of orthodontic arch wires from different manufacturers. Materials &amp; Methods: A cross sectional study was carried out on two arch wires manufactured by different companies (four Niti and three stainless steel) from different manufacturers. Surface profilometry was performed using a profilometer. Data were analyzed using Mann Whitney and Kruskal-Wallis tests. Results: The average surface roughness of Niti wires manufactured by Smart, American Orthodontics, OrthoTechnology and Allstar were: 1289±915 A°, 1378±372 A°, 2444±369 A° and 5242±2832 A° respectively. The average surface roughness of stainless steel wires manufactured by Allstar, Orthotechnology and American Orthodontics were: 710±210 A°, 1831±1156 A° and 4018±2214 A°. Stainless steel arch wire made by American orthodontics and nickel titanium arch wire made by Allstar showed the highest roughness significantly (P<0.006). Conclusion: Stainless steel arch wire made by American Orthodontics and nickel titanium arch wires manufactured by Allstar showed the highest surface roughness among the studied arch wires. Use of arch wires with least surface roughness is recommended.
