<br/><br/> The aim of this study was to evaluate and compare, the kinetic frictional force between two recent generation of frictionless brackets (fx SWLF and Damon 3MX), and one conventional bracket (Mini 2000). Material and methods: Seventy-two maxillary right stainless steel canine brackets, with slot size 0.022x0.028-inch, were used. The brackets were equally divided into three groups; Group  for the fx SWLF brackets, group  for the Damon 3 MX (self-ligated) brackets, while group  was for Mini 2000 conventional brackets
