Outline of Final Research Achievements

Metatranscriptomic analyses were performed to compare microbial species and functional genes in situ between peri-implantitis and periodontitis. Although the two diseases differed in terms of 16S rRNA-based taxonomic profiles, they showed similarities with respect to functional genes and taxonomic and virulence factor mRNA profiles. The latter, that was defined as microbial virulence types, differed from those of healthy periodontal sites. Networks based on co-occurrence relationships of taxonomic mRNA abundance (co-occurrence networks) were dissimilar between the two diseases. Peri-implantitis and periodontitis have shared as well as distinct microbiological characteristics.
