Summary

The oral cavity's microbiome is a diverse community, hosting over 700 bacterial species. Due to its varied niches, the oral cavity constitutes a highly complex environment where different microbes preferentially colonize distinct habitats. The aim of the study was to investigate the alteration of the oral microbiome during therapy with fixed orthodontic appliances using dietary supplements.

Detailed description

In the randomized clinical trial, the effect of dietary supplements (vegetable juice) was investigated in patients treated with fixed orthodontic appliances. Saliva, tongue and subgingival samples were taken from each participant at three different time points: TO (before insertion of fixed orthodontic therapy), T1 14 days after daily administration of lettuce juice; T2 up to 6 months after washout. Orthodontic patients without dietary intervention served as controls. In addition, clinical indices were examined. Samples were analyzed by Illumina 16S rRNA sequencing and taxonomically assigned.
