Comparison of the physico-chemical impact of chlorhexidine and silver nanoparticles on orthodontic appliances made with laser and silver solder: An in vitro study.

Objective: The aim of this study was to evaluate the physical-chemical changes in orthodontic devices made with laser and silver solder after immersion in different antiseptic solutions.

Methods: Wire/band assemblies were fabricated using different types of solders (silver and laser). The devices were immersed in different antimicrobial solutions (chlorhexidine - CHX 0.
