The destruction process of dental support tissues is explained by the activation of the innate cells (neutrophils and macrophages) by the use of the TLRs, mainly the TLR4, to recognize the LPS of predominant gram-negative anaerobic microorganisms in the subgingival plaque and is going to promote the transcription of inflammatory cytosine via NF-kB.

The most prevalent genotypes in these patients, both in the sample from subgingival plaque and strains found in blood, was fimA II, which agrees with that found by Enersen et al.
Pooled subgingival plaque samples were taken from primary canines and molars as well as permanent molars, by inserting sterile paper points into the deepest pockets of these teeth and allowing them to remain for 10 sec.

My work has established a correlation between the presence of disease and the presence of archaeal DNA, the severity of periodontal disease and the relative abundance of archaeal DNA in subgingival plaque. Although oral archaeal diversity is severely limited phylogenetic analysis of the two rDNA phylotypes deomonstrates that they were distinct from the previously isolated Methanobrevibacter oralis.
