Comparative <scp>16S rRNA</scp> gene sequencing study of subgingival microbiota of healthy subjects and patients with periodontitis from four different countries

Abstract

Periodontal diagnosis of the subjects was the main variable explaining the composition of the microbiota in the subgingival niche. Nevertheless, the country of origin also had a significant impact on the microbiota and is therefore an important factor to consider when describing subgingival bacterial communities.
