Anti-adhesion Study of Laser Welding Composite Arch Wire to Streptococcus Mutans

Abstract

Abstract: Objective: To study the anti-adhesive characteristics of composite arch wire of lased-welded nickel titanium arch wire and stainless steel arch wire with pure copper interlayer (CAW) with fluorescence microscope and scanning electron microscope. Methods: The nickel titanium arch wire, stainless steel arch wire copper wire and CAW unco-cultured with streptococcus mutans suspension were selected as experimental group. The nickel titanium arch wire, stainless steel arch wire copper wire and CAW co-cultured with streptococcus mutans suspension were selected as control group. The surface morphology was detected with fluorescent staining and scanning electron microscope after 48 hours. Results: The copper interlayer of CAW and copper wire showed red fluorescence of none bacterial adhesion area in experimental grous and control grous with fluorescent microscope. Less streptococcus mutans adhered to the copper interlayer of CAW than the nickel titanium arch wire,stainless steel arch wire, and composite arch wire nickel titanium parts, stainless steel parts. At the same time, the streptococcus mutans became dissolved and broken. Conclusion: The copper interlayer of CAW has certain anti-adhesive effect on streptococcus mutans.
