摘要：Introduction and objective. In recent decades the use of orthodontic appliances in Poland has increased; however, data
on their influence on changes of components of the microbiome connected with oral biofilm are scarce. The objective of
this study was to evaluate oral microbiota in terms of their role as risk factors for health complications.
Materials and method. The study included 100 patients treated with removable or fixed appliances. Oral hygiene and
gingival health were determined, and periodontal swabs taken from each patient for parasitological, bacteriological and
mycological microscopic and in vitro examinations.
Results. Oral protists and various pathogenic and opportunistic bacterial and fungal strains were identified in the superficial
layer of biofilm. A higher prevalence of bacteria, Enterococcus faecalis, E. faecium, Staphylococcus aureus and Escherichia
coli, and various strains of yeast-like fungi from the Candida albicans group, occurred in patients treated with the fixed
appliance than in those using a removable appliance or not treated orthodontically. In some periodontal samples from
patients treated with fixed appliances, cysts of the Acanthamoeba spp. were found.
Conclusions. The use of orthodontic appliances alters the status of the oral cavity; it has impact on the colonization of
oral biofilm by opportunistic/pathogenic strains, and increases the risk of their dissemination to various human tissues and
organs. Pretreatment examination of oral microbiome, its monitoring particularly during treatment with fixed appliances,
and preventive elimination of the potentially pathogenic strains to avoid health complications, are highly recommended,
especially in patients with impaired immunity.
