The effects of different orthodontic appliances upon microbial communities.

Objectives: Orthodontic appliances can promote accumulation of dental plaque, with associated enamel decalcification or gingival inflammation. The aim of this study was to examine longer-term microbiological changes during orthodontic treatment with fixed appliances.

Materials And Methods: Twenty-four orthodontic patients aged 11-14 years undergoing fixed appliance therapy were recruited into the study.
