BACKGROUND Six serotypes of Porphyromonas gingivalis have recently been described. We sought to test the hypothesis that serotype specific carbohydrates from these strains are important antigens that elicit potent immune responses. METHODS Serum concentrations of IgG reactive with P. gingivalis serotypes K1-K6 were determined for 28 adult (AP) and 28 generalized early-onset (G-EOP) periodonti...
Periodontal Ehlers-Danlos syndrome (pEDS) is an autosomal-dominant disorder characterized by early-onset periodontitis leading to premature loss of teeth, joint hypermobility, and mild skin findings. A locus was mapped to an approximately 5.8 Mb region at 12p13.1 but no candidate gene was identified. In an international consortium we recruited 19 independent families comprising 107 individuals ...
Although periodontitis is a chronic inflammatory disease but some factors of acute inflammation phase are involved in this disease among which is the C-Reactive protein (CRP). To minimize its effects, anti-inflammatory drugs or non-pharmacological approaches such as oral hygiene is recommended. CRP can also be used for the prediction and early detection of periodontal disease. The aim of the pr...
OBJECTIVES Microbiological laboratory procedures are involved in diagnosis and therapy control of progressive and refractory forms of periodontitis. In recent years techniques have been developed based on the detection of nucleic acids. The purpose of this study was to validate the commercially available micro-Dent(R) test which employs probes for A. actinomycetemcomitans, P. gingivalis, P. int...
Based on the prevailing understanding of the distribution and etiology of periodontal disease, different methods have been introduced to evaluate periodontitis in epidemiological and clinical situations. This article discusses the recording methods used to investigate the epidemiology of early periodontitis.
Periodontal diseases are the inflammatory diseases triggered specifically by some selected microorganisms, i.e., periodontopathic bacteria, accumulated in and around the gingival crevice. Among periodontopathic bacteria, Porphyromonas gingivalis, a black-pigmented gram-negative anaerobic rod, has been implicated as a major pathogen of chronic periodontitis (Hamada et al., 1991; Lamont & Jenkins...
AIM The aim of this study was to determine the association between periodontitis and the incidence of preterm birth (PB), low birth weight (LBW) and preterm low birth weight (PLBW) MATERIAL AND METHODS: One thousand and ninety-six women were enrolled. Periodontal data, pregnancy outcome variables and information on other factors that may influence adverse pregnancy outcomes were collected. Data...
BACKGROUND AND AIMS Periodontitis is a common chronic adult condition that implicates oxidative damage to gingival tissue, periodontal ligament and alveolar bone. This study aimed at assessing the association between the nitro-oxidative stress and the periodontal tissues destructions in experimental rat periodontitis. METHODS Periodontitis was induced in 15 male albino rats by repetitive lesi...
Toll-like receptor (TLR) signaling is thought to be one of the most important pathways initiating periodontitis onset. We have previously reported that the TLR signaling pathway is upregulated in periodontitis-affected gingival tissues by microarray pathway frequency analysis. The aim of the present study was to quantitatively analyze specific upregulated genes in the TLR signaling pathway, as ...
Periodontitis is one of the most common oral diseases and is characterised by gingival inflammation and alveolar bone resorption (Savage et al. 2009). Periodontitis is a multifactorial irreversible and cumulative condition, initiated and propagated by bacteria and host factors (Kinane 2001). More than 500 different bacterial species are able to colonise the oral biofilm and up to 150 different ...
