Previous studies have demonstrated that the hydrolysis of the trypsin substrate N-benzoyl-DL-arginine-2-naphthylamide (BANA), by subgingival plaque obtained from a single site, correlates best with the numbers and proportions of spirochetes in plaque samples and may serve as an indicator of clinical disease.

av N Schwech — Comparative effectiveness of ultrasonic and hand scaling for the removal of subgingival plaque and calculus. J Periodontol. 1987; 58: 9–18. 20. Gellin RG, Miller METHODS: Subgingival bacterial plaque was collected from women > or =6 months after delivery. Bacteria were assessed by the checkerboard DNA-DNA Disease Severity Associated with Presence in Subgingival Plaque of Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, and Tannerella Microbial analysis of subgingival plaque samples compared to that of Haririan, Hady; Andrukhov, Oleh; Bertl, Kristina; Lettner, Stefan; Kierstein, Sonja; Moritz, Materials and Methods Gingival tissue and subgingival plaque samples were collected from 21 periodontitis patients including 48 periodontal pocket sites with Subgingival plaque microbiota in Saudi Arabians after use of miswak chewing stick and toothbrush.

It is the main cause of cavities and gum disease, and can harden into Close. Indian J Med Microbiol. Figure 2: (a) Subgingival plaque samples being taken using paper points. (b) Irrigation tip being placed into the pocket for Close. Indian J Med Microbiol. Figure 2: Subgingival plaque collection.

– Structure of nucleatum originated from mother's subgingival plaque (Han et al., 2010; Han and Wang, 2012). F. nucleatum has also been associated with a number of other Feb 7, 2017 Keywords: generalized aggressive periodontitis, metagenome, subgingival plaque, non-surgical treatment, bacterial community shifts. There are two types of plaque; plaque which forms above the gums ( supragingival) and that which forms below the gums (subgingival).

Some of the late-colonizing species of oral biofilms display greater pathogenic potential than the predominant species during early plaque formation(2). The

The primary outcome measure was the frequency of periodontopathogen in the subgingival plaques, which referred to the percentage of the patients or teeth positive for periodontopathogens. The collection of subgingival plaque samples is the common way for the determination of periodontopathic bacteria. However, recently, salivary analysis has been discussed as an advantageous future diagnostic method for periodontitis because it offers simple quantitative sampling and the possibility to assess various bacteria. 28 Microbiology—Subgingival Plaque Extending apically from the supragingival region, a subgin-gival plaque biofilm will often form within the existing gin-gival sulcus/pocket; this was previously called the “adhe-rent” plaque.

Subgingival plaque contains a higher proportion of anaerobic bacteria, or those bacteria which cannot exist in an environment containing oxygen. Several anaerobic plaque bacteria, such as Porphyromonas gingivalis , [19] secrete antigenic proteins that trigger a strong inflammatory response in the periodontium , the specialized tissues that surround and support the teeth.

Flowchart 9.4: The plaque accumulates in the small gaps between teeth, in the gingival grooves Subgingival microorganism (those that exist under the gum line) colonize the Subgingival plaque is most likely to contain the anaerobic bacteria that cause periodontal disease. Remember that although calculus is a secondary etiologic Plaque is a sticky, colourless film of bacteria and sugars that constantly forms on our teeth. It is the main cause of cavities and gum disease, and can harden into Close.

We aimed to study H2S production from subgingival plaque samples in relation to disease severity in subjects with natural development of the disease, using a colorimetric method based on bismuth precipitation. Subgingival plaque was analyzed from healthy subjects and subjects with refractory periodontitis, adult periodontitis, human immunodeficiency virus periodontitis, and acute necrotizing ulcerative gingivitis. 16S ribosomal DNA (rDNA) bacterial genes from DNA isolated from subgingival plaque samples were PCR amplified with all-bacterial or selective primers and cloned into Escherichia coli . Such findings cast doubt on the validity of using histologic and disclosing stains as an indicator for the presence of bacterial plaque immediately after instrumentation.

From pooled subgingival plaque, 16S and 18S rDNA were cloned and sequenced to determine species identity. RESULTS: One hundred and nine bacterial species were identified from 14 subjects. Nearly half of the species were not cultivable.

Subgingival plaque contains a higher proportion of anaerobic bacteria, or those bacteria which cannot exist in an environment containing oxygen. Several anaerobic plaque bacteria, such as Porphyromonas gingivalis , [19] secrete antigenic proteins that trigger a strong inflammatory response in the periodontium , the specialized tissues that surround and support the teeth. 1.
