The 2 most frequent isolates were Bacteroides ruminicola ss. brevis and a Selenomonas species, neither of which is a recognised periodontopathogen. The gel had a rapid effect on the viability of the bacteria in the plaque samples, the 90% kill time being 17 min or less for 90% of the samples (range less than 5 to 71 min). PMID: 2387913

Study on the Prevalence of Periodontopathogenic Bacteria in Serum and Subgingival Bacterial Plaque in Patients with Rheumatoid Arthritis MARIA ALEXANDRA MARTU 1 , SORINA MIHAELA SOLOMON*, IRINA

Plaque absorbs calcium and phosphate from saliva for the formation of supragingival calculus and from crevicular fluid for the formation of subgingival calculus. Calcium phosphate The effects of minocycline on subgingival plaque samples from patients with chronic periodontitis were investigated in vitro. Minocycline concentrations as low as 1.0 microgram/ml inhibited 95.7% of the cultivable bacteria in the samples but 256 micrograms/ml was necessary to inhibit all of the cultivable bacteria in the samples. 2013-04-22 · Diabetes mellitus is a major risk factor for chronic periodontitis.

The effects of phenoxyethanol, chlorhexidine and a mixture of both on subgingival plaque samples from 44 patients with chronic periodontitis were investigated in vitro. At a concentration of 0.5 mg/ml, chlorhexidine inhibited the growth of all cultivable bacteria in all 44 samples while a comparable effect was achieved with phenoxyethanol only at a concentration of 20 mg/ml. Calcification times can vary from person to person, depending on their salivary pH and the amount of calcium and other substances in their saliva. Once calculus forms, it then attracts more plaque, which in time can become another layer of calcified material. Characteristics of Subgingival Calculus The purpose of this study was to determine the bacterial diversity in the human subgingival plaque by using culture-independent molecular methods as part of an ongoing effort to obtain full 16S rRNA sequences for all cultivable and not-yet-cultivated species of human oral bacteria.

The aim of the present study was to visualize, identify and quantitate red complex bacteria from the subgingival plaque of healthy individuals and patients with chronic periodontitis using FISH and evaluate its applicability as a diagnostic tool in periodontology.

2012-08-15 · Ali et al. (1994) found that P. intermedia was always detected in the presence of F. nucleatum in subgingival plaque samples from deep pockets in a group of adult periodontitis subjects.

Subgingival pla …. It has been recognized for some time that bacterial species exist in complexes in subgingival plaque. In vivo, P. gingivalis and T. denticola are frequently found to co-exist in deep periodontal pockets and have been co-localized to the superficial layers of subgingival plaque as microcolony blooms adjacent to the pocket epithelium, suggesting possible interbacterial interactions that contribute towards disease. Results: All bacterial species were detected in salivary and subgingival plaque samples.

Bacteroides is a genus of gram-negative, obligate anaerobic, nonsporulating bacilli that belong to the family Bacteroidaceae. Members of this genus are chemoheterotrophs and can use carbohydrates, peptone, and other intermediate bacterial metabolites. Bacteroides are naturally found in the mouth, tongue, intestinal tract, and vagina.

Although up to 99.9% of bacteria in the plaque samples were Subgingival microbial profile associated with periodontitis has been reported to significantly differ by geographical location. The purpose of this study was to assess the association between a panel of putative periodontal bacterial pathogens and chronic periodontitis among Yemenis.
