Marginal periodontitis is not a homogeneous disease but is rather influenced by an intricate set of host susceptibility differences as well as diversities in virulence among the harbored organisms. It is likely that clonal heterogeneity of subpopulations with both high and low levels of pathogenicity exists among organisms harbored by individuals with negligible, slight, or even severe periodon...
The aim of this study was to assess the relationship-between Porphyromonas gingivalis, Epstein-Barr virus (EBV) infection and reactivation in periodontitis using real-time PCR. The mean proportion of P. gingivalis cells to total bacterial cells in the saliva from EBV-positive periodontitis patients was significantly higher than that in saliva from EBV-negative patients. An EBV-positive B-cell l...
PURPOSE Prevention of peri-implantitis is essential for the success of implant rehabilitation. Infection by periodontopathic bacteria is a major cause of peri-implantitis. The aim of the present study was to identify the source of peri-implant colonization by periodontopathic bacteria. MATERIALS AND METHODS Twenty-one patients with implants were enrolled in the study. Subgingival plaque sampl...
OBJECTIVE To evaluate the variations in the detection of Porphyromonas gingivalis and/or Aggregatibacter actinomycetemcomitans before and after systemic administration of amoxicillin plus metronidazole in association with non-surgical periodontal therapy (NSPT). BACKGROUND The adjunctive use of antibiotics has been advocated to improve the clinical outcomes of NSPT. However, no systematic rev...
Accumulating evidence suggests the involvement of Porphyromonas gingivalis (P. gingivalis), a periodontal pathogen, in cardiovascular diseases. Clinical specimens of aneurysmal tissue and dental plaque collected from patients infected with or without P. gingivalis were analyzed. The number of aneurysms in the distal aorta in the P. gingivalis-infected group was significantly higher than that in...
Porphyromonas gingivalis is considered a major pathogen in adult periodontitis and is also associated with multiple systemic diseases, for example, cardiovascular diseases. One of its most important virulence factors is invasion of host cells. The invasion process includes attachment, entry/internalization, trafficking, persistence, and exit. The present review discusses these processes related...
Kartheyaene Jayaprakash (2016): Monocyte and Neutrophil Inflammatory Responses to the Periodontopathogen Porphyromonas gingivalis. Örebro studies in Medicine 138 Periodontitis is one of the most common adult infections. Duing bacteremia in healthy individuals or patients with chronic periodontitis, a number of oral bacteria such as Porphyromonas gingivalis encounter inflammatory cells in the bl...
The gram-negative anaerobic bacterium Porphyromonas gingivalis is a major causative agent of chronic periodontitis. Porphyromonas gingivalis strains have been classified into virulent and less-virulent strains by mouse subcutaneous soft tissue abscess model analysis. Here, we present the whole genome sequence of P. gingivalis ATCC 33277, which is classified as a less-virulent strain. We identif...
Objective Halitosis can be caused by microorganisms that produce volatile sulphur compounds (VSCs), which colonize the surface of the tongue and subgingival sites. Studies have reported that the use of natural products can reduce the bacterial load and, consequently, the development of halitosis. The aim of this study was to evaluate the antimicrobial activity of the essential oil of Melaleuca ...
