Abstract
TM7 is an uncultivated organism which is present in extremely diverse environments. Members of the Dialister genus are difficult to culture as a result of which many of these strains remain uncultivated. It has been suggested that TM7 and Dialister bacteria may belong to a group of suspected periodontal pathogens. In our current study, the presence of the sebacteria in Korean dental plaque samples was assessed using PCR detection methods with specific primers for 16S ribosomal RNA genes. The experimental group included 84 volunteers (35 males and 49 females). Plaque samples were collected from 4 non-adjacent proximal sites of the molar areas of the mandible in each subject and pooled. TM7 was detectable in 56% and the Dialister genus in 27.5% of the volunteers. Both TM7 and Dialister were present in 20.3% of volunteers. We found that 36.9% of the volunteers were negative for both bacteria. Further studies to evaluate the prevalence of these putative pathogenic bacteria in the Korean population are warranted.
