The Oral Microbiome in Periodontal Health.

The estimation of oral microbiome (OM) taxonomic composition in periodontally healthy individuals can often be biased because the clinically periodontally healthy subjects for evaluation can already experience dysbiosis. Usually, they are included just based on the absence of clinical signs of periodontitis. Additionally, the age of subjects is used to be higher to correspond well with tested groups of patients with chronic periodontitis, a disorder typically associated with aging.

R/G Value-A Numeric Index of Individual Periodontal Health and Oral Microbiome Dynamics.

The dysbiosis of oral microbiome (OM) precedes the clinical signs of periodontal disease. Its simple measure thus could indicate individuals at risk of periodontitis development; however, such a tool is still missing. Up to now, numerous microbial taxa were associated with periodontal health or periodontitis.

C-reactive protein in patients with aggressive periodontitis.

Background/purpose: The aim of this study was to evaluate and compare the systemic levels of C-reactive protein (CRP) in peripheral blood samples of patients with aggressive periodontitis during the first twelve months of periodontal treatment, at exactly six month interval measurements, and compare them with clinical periodontal parameters.

Materials And Methods: All patients (N = 45) were examined prior to the initiation of periodontal treatment. Patients were divided into two groups GAgP (Generalised form of aggressive periodontitis, N = 23) and group LAgP (Localised form of aggressive periodontitis, N = 22).

Proteomic analysis of human tooth pulp proteomes - Comparison of caries-resistant and caries-susceptible persons.

Unlabelled: Most people in the world suffer from dental caries, >90% of adults experience caries on enamel and root surfaces during their life. However, the overall roles of all factors in the development of dental caries still remain unclear and are worthy of recent investigation. In this study we used a proteomic 2D-DIGE approach in connection with MS/MS to investigate the different protein abundances in the tooth pulp of human third molars obtained from caries-resistant and caries-susceptible people.

C-Reactive Protein in Peripheral Blood of Patients with Chronic and Aggressive Periodontitis, Gingivitis, and Gingival Recessions.

CRP is a plasma protein that reflects a measure of the acute phase response to inflammation and is one of the markers of choice in monitoring this response. CRP can be used for the prediction and early detection of periodontal disease. The aim of this study was to compare and evaluate the systemic levels of CRP in the peripheral blood samples of patients with chronic and aggressive periodontitis, gingivitis, and gingival recessions and compare them with periodontal clinical parameters.

Periodontitis as a risk factor of atherosclerosis.

Over the last two decades, the amount of evidence corroborating an association between dental plaque bacteria and coronary diseases that develop as a result of atherosclerosis has increased. These findings have brought a new aspect to the etiology of the disease. There are several mechanisms by which dental plaque bacteria may initiate or worsen atherosclerotic processes: activation of innate immunity, bacteremia related to dental treatment, and direct involvement of mediators activated by dental plaque and involvement of cytokines and heat shock proteins from dental plaque bacteria.

Porphyromonas gingivalis: major periodontopathic pathogen overview.

Porphyromonas gingivalis is a Gram-negative oral anaerobe that is involved in the pathogenesis of periodontitis and is a member of more than 500 bacterial species that live in the oral cavity. This anaerobic bacterium is a natural member of the oral microbiome, yet it can become highly destructive (termed pathobiont) and proliferate to high cell numbers in periodontal lesions: this is attributed to its arsenal of specialized virulence factors. The purpose of this review is to provide an overview of one of the main periodontal pathogens-Porphyromonas gingivalis.

The prevalence of environmental mycobacteria in drinking water supply systems in a demarcated region in Czech Republic, in the period 1984-1989.

The presence of environmental mycobacteria was studied in drinking water supply systems in Olomouc Country, Czech Republic, in order to detect the possible spread of M. kansasii from the neighbouring region in Ostrava County. Drinking water samples from water supply systems of 16 identical localities were investigated.

The spring-fall variations in the prevalence of environmental mycobacteria in drinking water supply system.

The fluctuation in the prevalence of environmental mycobacteria in relation to nutritional conditions in nature was repeatedly described in literature. The seasonal difference in potable water supply system has not yet been documented. Potable water samples from water supply systems of 16 localities were analyzed.

The prevalence of environmental mycobacteria in drinking water supply systems in Olomouc County, north Moravia, Czech Republic, in the period 1984-1989.

The presence of environmental mycobacteria was studied in drinking water supply systems in Olomouc County, Czech Republic, in order to detect the possible spread of M. kansasii from the neighbouring region in Ostrava County. Drinking water samples from water supply systems of 16 localities were investigated.

[Spontaneous and induced fetal movement activity in the 2d trimester of pregnancy].

During routine screening in the first half of pregnancy the authors evaluated in 3446 foetuses the incidence of spontaneous movements and movements after their attempted induction by movement of the uterus, when no spontaneous movements were recorded during examination. The examinations were made by means of a rotation probe 3.5 MHz of a Sonoline 2 apparatus (Siemens) always between 7.

Comparison of microscopic positivity in smears from sputa stained according to Ziehl-Neelsen in different modifications.

Some basic factors influencing the detection of microscopic positivity in the sputa of patients with tuberculosis of the lungs, stained according to Ziehl-Neelsen in various modifications, were studied in 9 laboratories in 5 different countries (Bulgaria, Czechoslovakia, Mongolia, German Democratic Republic and Poland). Each laboratory prepared 200 coded slides from 50 suspect-positive sputa. The slides were stained using four different methods and despatched, without examination, to the next laboratory in the series.
