Bacteriological Assessment of Mini Anchorages Retrieved Following Maxillary Treatments Using Mini Anchorage-Assisted Orthodontic Appliances

In recent years, mini screws used in the mouth have been widely used in orthodontics clinics to provide dental movements and to increase skeletal anchorage. In this study, bacteria were isolated from mini screws taken from patients who were treated in the Orthodontic Department of Eskişehir Osmangazi University Faculty of Dentistry Clinic and routinely applied mini screws to the anterior and posterior regions of the upper palate for jaw widening or support of dental movements. Streptococcus salivarus (15 isolates), Streptococcus anginosus (12 isolates) and Enterococcus feacalis (10 isolates) were the most isolated bacteria in the microbial composition. Rothia mucilaginosa (8 isolates) and Corynebacteria argentoratense (6 isolates) were isolated from the Actinobacteria phylum. Neisseria oralis, N. flava, N. subflava and N. flavescens species were determined from Proteobacteria phylum.
