Abstract: | Periodontitis is an inflammatory disease of the periodontal tissues, which can lead to tooth loss. It has been described that a dysbiotic subgingival biofilm can be the cause of such inflamation, and therefore many efforts have focused in the characterization of the microbiota that might cause periodontitis. These studies have built microbial profiles of the healthy and periodontitis-related subgingival biofilm, although based in local populations and without taking into account the variability that the geographical origin can add to the samples, thus creating a bias when universalizing such profiles. In order to assess if there are significant differences among the subgingival microbiota of healthy subjects and patients with periodontitis of 4 different geographical origins (Belgium, Peru, Chile and Spain), subgingival samples were analyzed using next generation sequencing, evaluating their diversity, richness and bacterial composition according to their diagnostic and geographical origin. Sequences wereprocessed through the software mothur and the statistical analyses were performed using the R statistical packages PhyloSeq, Vegan and DESeq2. Results showed that there are significant differences in the samples, both by diagnostic and by geographical origin, which opens the door to further studies in order to analyze the causes and consequences of such variability. |
