Objective: The aim of this study was to determine the effects of a fluoride prophylactic agent on the mechanical properties and surface quality of a preformed round translucent composite archwire comparing it with a nickel-titanium and a multistranded stainless steel wires. Materials and Methods: The wires were immersed in either an acidulated fluoride solution (APF) or distilled water (control) for 1.5 hours at 37o C. Flexural modulus of elasticity (E) and yield strength (YS) of the wires were measured using a 3-point bending test in a Universal Testing Machine. Springback ratio (YS/E) was calculated for each wire. The influence of fluoride treatment on properties of the wires was statistically analyzed using a student's t-test at ; = 0.05. Surface changes were observed with a scanning electron microscope. Results: Fluoride treatment produced a statistically significant reduction in E, YS and YS/E of the composite wire (P < 0.05). In addition, a significant decrease in E of Ni-Ti wire was found after exposure to fluoride, comparing it with distilled water control treatment. On the other hand, no significant effect of fluoride treatment was found on YS and YS/E of Ni-Ti wire and also on the studied properties of the multistranded stainless steel wire (p > 0.05). Corrosive changes in surface topography were observed after exposure to the fluoride agent, which were more pronounced with the composite wire. Conclusions: The results suggest that using topical fluoride agent with translucent composite wire could decrease mechanical properties and might damage surface of the wire, which potentially contribute to prolonged orthodontic treatment.
