Objectives:  To evaluate the dynamic frictional resistance of coated stainless steel wires and non coated stainless steel wires in conventional stainless steel bracket system.   Materials and Methods: The study was performed using specially designed apparatus that included 10 aligned brackets to compare the frictional resistance generated by conventional stainless steel brackets(0.022” slot) coupled with stainless steel, fully coated stainless steel and labially coated stainless steel archwires of varying dimensions by Universal Testing Machine. (Instron Machine, Model No.4501) Each bracket–archwire combination was tested 13 times. The data obtained were subjected to statistical analysis.   Results: Stainless steel archwire (16x22) shows least frictional mean values when compared to the varying dimensions and surface characteristic of archwires. (19X25)Teflon coated (Fully coated) stainless steel archwire shows highest frictional mean values when compared to the varying dimensions and surface characteristic of archwires. Fully coated archwires shows more frictional values than labially coated archwires and conventional stainless steel archwires.   Conclusions: Teflon coated (Fully coated) stainless steel archwire shows more friction than Labially coated stainless steel archwires and also more amount of friction than stainless steel archwires. Stainless steel archwire shows least frictional resistance values than Coated stainless steel archwires and also frictional values increased when the size of archwire increased.
