Description
Plaque and enamel demineralization can occur when orthodontic archwires are present in the oral cavity because they make oral hygiene more difficult and provide a unique surface for bacterial adhesion. Dental caries are thought to be caused by the adhesion and colonization of mutans streptococci on these surfaces. This research was conducted with the purpose of testing and comparing the adhesion of mutans streptococci to a variety of aesthetic archwires as well as a conventional archwire made of NiTi.
