Relationship between periodontal infections and systemic disease

TL;DR: From data, it is clear that oral infection may represent a significant risk-factor for systemic diseases, and hence the control of oral disease is essential in the prevention and management of these systemic conditions.
Journal ArticleDOI

Oral pathobiont induces systemic inflammation and metabolic changes associated with alteration of gut microbiota.

TL;DR: Investigation of changes in the gut microbiota, insulin and glucose intolerance, and levels of tissue inflammation in mice after oral administration of Porphyromonas gingivalis provided a new paradigm for the interrelationship between periodontitis and systemic diseases.
Journal ArticleDOI

Periodontal manifestations of systemic diseases and developmental and acquired conditions: Consensus report of workgroup 3 of the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions.

TL;DR: In this paper, the authors reviewed and updated the 1999 classification with regard to these diseases and conditions, and developed case definitions and diagnostic considerations, which is based on the results of these reviews and on expert opinion of the participants.
Journal ArticleDOI

Periodontal manifestations of systemic diseases and developmental and acquired conditions: Consensus report of workgroup 3 of the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions: Classification and case definitions for periodontal manifestations of systemic diseases and developmental and acquired conditions

TL;DR: An updated classification of theperiodontal manifestations and conditions affecting the course of periodontitis and the periodontal attachment apparatus, as well as of developmental and acquired conditions, is introduced.
Journal ArticleDOI

Oral Administration of P. gingivalis Induces Dysbiosis of Gut Microbiota and Impaired Barrier Function Leading to Dissemination of Enterobacteria to the Liver

TL;DR: Changes in gut microbiota preceded systemic inflammatory changes and support the idea that disturbance of the gut microbiota composition by orally derived periodontopathic bacteria may be a causal mechanism linking periodontitis and systemic disease.
