Objectives-Microorganism adhesion on coated (SS and NiTi) and uncoated (SS and NiTi) orthodontic archwires after clinical use. correlation between surface roughness (SR) and bacterial colonization was evaluated. Methods-A total of 40 archwire segments (0.016 * 0.022-in) were equally divided into 4 groups: nickel-titanium coated, nickel-titanium uncoated, uncoated stainless steel, and coated SS. The archwires were randomly inserted. After 4 weeks of clinical use, the total number of microorganisms adhering to the archwire was quantified and transformed into colonyforming units. SR was evaluated using a SEM
