TL;DR: A new periodontitis classification scheme has been adopted, in which forms of the disease previously recognized as "chronic" or "aggressive" are now grouped under a single category ("periodontitis") and are further characterized based on a multi-dimensional staging and grading system as mentioned in this paper.

TL;DR: Differences between health- and periodontitis-associated bacterial communities were observed at all phylogenetic levels, and UniFrac and principal coordinates analysis showed distinct community profiles in health and disease.

TL;DR: In this article, the purpose of the present investigation was to identify potential periodontal pathogens among newly identified species and phylotypes, and species-specific ribosomal 16S primers for PCR amplification were developed for detection of new species.

TL;DR: Chronic periodontitis is the result of a global perturbation of the oral bacterial ecology rather than a disease-site specific microbial shift, and more differences were found in the bacterial profile between subjects withperiodontitis and healthy subjects than between deep and shallow sites within the same subject.
