Orthodontic fixed appliance therapy is the commonest mode of treatment for most types of malocclusions (teeth irregu larities). However, these materials are liable for microbial adhesion, which predisposes the wearer to increased micro bial burden. The present study aims to evaluate, microbial adhesion and growth on commonly used orthodontic ligating materials (Teflon coated wire, stainless steel wire, elastic rings) under in vitro condition. Furthermore, the role of saliva on adhesion and microbial colonization on said materials was also assessed. Experiments were conducted with three different orthodontic ligating materials each in 6 numbers. Growth OD, metabolic activity and cell viability were the experimental variables in addition to SEM (Scanning Electron Microscopy) analysis performed. Results revealed ire spective of the nature of the ligating materials, microbial adhesion and growth were observed in all the materials and suggested that the chosen materials promotes microbial adhesion. Nevertheless, stainless steel ligatures were less prone to adhesion compared to Teflon coated and elastic ligatures. Presence of saliva accelerates adhesion and growth.
