Red‐Complex Bacterial DNA in Carotid Atheroma of Dentate and Long‐Term Edentulous Patients and Its Association With Mitochondrial DNA Copy Number

Oral Diseases, EarlyView.
ABSTRACT Objective This study aimed to evaluate (i) the presence of red complex bacteria in carotid atheroma plaques of dentate and edentulous patients and (ii) the possible relationship between mitochondrial DNA copy number (mtDNA‐cn), an indicator of mitochondrial function, and periodontal disease.

Intracellular localization of Treponema denticola chymotrypsin-like proteinase in chronic periodontitis

Journal of Oral Microbiology, 2014
Treponema denticola is an important periodontal pathogen capable of tissue invasion. Its chymotrypsin-like proteinase (CTLP) can degrade a number of basement membrane components in vitro, thus suggesting a contribution to tissue invasion by the ...

Periodontitis‐Associated Bacteria and Their Connection to Proinflammatory Biomarkers in Periodontal Pockets: A Clinical Microbiological Study

Oral Diseases, EarlyView.
ABSTRACT Background This study examines the relationship between the microbial load of selected periodontitis‐associated bacteria (PAB) and proinflammatory biomarkers in gingival crevicular fluid (GCF) from patients with periodontitis. Methods GCF and subgingival biofilm samples were collected from the deepest periodontal pocket of each quadrant of 515

Killing of Treponema denticola by Mouse Peritoneal Macrophages

Journal of Dental Research, 2010
Treponema denticola has been identified as an important cause of periodontal disease and hypothesized to be involved in extra-oral infections. The objective of this study was to investigate the role of T. denticola cell length and motility during mouse peritoneal macrophages in vitro uptake. Macrophages, incubated under aerobic and anaerobic conditions,

Association Between Periodontitis and Respiratory Diseases: A Systematic Umbrella Meta‐Analysis

Oral Diseases, EarlyView.
ABSTRACT Aim This study aimed to evaluate the association between periodontitis and respiratory diseases using an umbrella meta‐analysis. Methods Meta‐analyses (MAs) reporting odds ratios (OR) and mean differences (MD) for the association between periodontitis and respiratory diseases of COVID‐19, chronic obstructive pulmonary disease (COPD), asthma ...

Characteristics of the Health‐Associated Oral Microbiome in Young Nonhuman Primates

Molecular Oral Microbiology, EarlyView.
The oral microbiome of healthy younger nonhuman primates, as a preclinical model of the human oral cavity, was evaluated. The results provide seminal details of the oral microbiome in this disease model to elucidate specific microbial changes.

Isolation and characterization of a plasmid fromTreponema denticola

FEMS Microbiology Letters, 1991
Agarose gel electrophoresis of whole genomic DNA of the oral spirochaete Treponema denticola has revealed a plasmid-like fraction. Purification and restriction enzyme analysis has confirmed the presence of a 2.6-kb circular plasmid, which has been mapped for restriction sites and cloned into the Escherichia coli plasmid pUC18. Southern blot analysis of

An investigation of the presence of specific anaerobic species in necrotic primary teeth

Brazilian Oral Research, 2013
Different microbial identification methods have shown that the microbial community profiles in endodontic infections are diverse and assorted. The aim of this study was to evaluate the frequency of selected endodontic pathogens in the pulp chambers (PCs)

Red-complex bacteria: immunological background leading to the development of head and neck cancers

Frontiers in Immunology
Oral microbiome imbalance is involved in the development of head and neck cancers (HNCs). There is a group of oral pathogens, such as Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola, that creates red-complex.

Detection of Porphyromonas gingivalis and Treponema denticola in chronic and aggressive periodontitis patients: A comparative polymerase chain reaction study

Contemporary Clinical Dentistry, 2016
Background: The detection frequency of Porphyromonas gingivalis and Treponema denticola in chronic periodontitis (CP) and aggressive periodontitis (AgP) is not explored well in Indian population. Aim: The study was undertaken to detect P.
