From: Effect of fixed orthodontic appliances on gingival status and oral microbiota: a pilot study
Differences in the percentages of 3 selected cariogenic (Streptococcus mutans, Lactobacillus sp., Actinomyces sp.) and 7 periodontal bacteria (Aggregatibacter actinomycetemcomitants, Tannarella forsythia, Porphyromonas gingivalis, Prevotella intermedia, Treponema, Denticola, Parvimonas micra, Fusobacterium nucleatum) relative to the total prokaryotic DNA at two time points – T0 (before bonding of fixed orthodontic appliances) and T1 (till the end of 7th month after bonding of fixed orthodontic appliances) in 30 patients. Full circle, patient with deterioration of oral bacterial composition; empty circle, patient with unchanged or improved oral bacterial composition; statistical significance was calculated using the Wilcoxon matched-pairs signed-rank test
