SUPRAGINGIVAL PLAQUE/BIOFILM REMOVAL Cleans soft deposits from tooth surfaces • The versatility of AIR-FLOW ensures that plaque/supragingival biofilm is quickly and efficiently removed from supragingival surfaces. • Once all of the plaque is gone, it is easier to detect calculus, and rubber cup/paste is not needed.

DNA was then extracted from plaque samples and analyzed by 16S rRNA gene sequencing. CLSM images of 10-species ‘subgingival’ in vitro biofilms grown in parallel for 64.5 h on hydroxyapatite (HA) discs in 50% serum/50% medium and then fluorescence-labeled by multiplex FISH.a 3D Se hela listan på periobasics.com 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. In addition to gram-positive bacteria such as streptococci, actinomyces, etc., as the probing depth in- Subgingival plaque biofilm phase In which phase of periodontal disease progression do the increasing numbers of PMNs rush to the site of the periodontal pathogens and in doing so destroy healthy gingival connective tissue and migrate through the JE to form a "wall of cells" between the plaque biofilm and the sulcus wall? Established gingivitis- subgingival plaque phase Established lesion (21 days) -Biofilm extends subgingivally and disrupts the attachment of the coronal-most portion of the JE -Macrophages and lymphocytes are most numerous in the connective tissue; antibodies produced Conclusions: The biofilm model described here closely reproduces the composition of the cultivable subgingival plaque both in the species present and in their relative proportions. Differences existed between biofilms grown from diseased and non‐diseased sites with the former being characterized by the presence of periodontal pathogens at microbially significant levels. The growth and development of biofilm are characterized by 4 stages: initial adherence, lag phase, rapid growth, and steady state.

ally dominate the maturing plaque biofilm (Scheie, 1994).

Dental biofilm + long time periods without removal of the biofilm + sucrose consumption + low pH = increase in biofilm mass and in cariogenic bacteria in the biofilm leading to plaque formation. When more cariogenic bacteria are present in the plaque the pH remains at or below pH5.5 for longer periods of time resulting in demineralization of tooth enamel.

Using the checkerboard technique, which consists of DNA-DNA hybridisation (Socransky et al., 1994)4 using specific probes for 40 bacterial species, subgingival plaque was determined to contain bacterial species integrated in different clusters (red, orange, green, yellow, etc.).

Biofilms have been described in many systems since Van Leeuwenhoek examined the “animalcules” in the plaque on his own teeth in the seventeenth century, but the general theory of biofilm predominance was not promulgated until 1978 when Costerton invented the word “biofilm”, referring to the matrix-enclosed bacterial community 11. The

We describe an in vitromulti-species biofilm model of subgingival plaque that closely mimics the composition and proportions of the cultivable bacterial taxa recovered from the gingival crevice and/or periodontal pocket and that is relatively representative of the bacteria recovered from both healthy and diseased periodontal sites. In supragingival plaque, the relationship between community composition and location within the biofilm is not apparent to the naked eye because biomass is very low and the organisms lack pigmentation. Also, the metabolic relationships between the community subunits are not clearly defined. Periodontal treatment includes four main stages: systemic phase, initial hygiene phase, corrective phase and maintenance. a condition initiated by the subgingival dental plaque biofilm on subgingival plaque. Certain bacterial comple xes are associated with health or disease. 10,11 For example, the bacteria in the red complex are more likely to be associated with clinical indicators of periodontal disease such as periodontal pock eting and clinical attachment loss.

When more cariogenic bacteria are present in the plaque the pH remains at or below pH5.5 for longer periods of time resulting in demineralization of tooth enamel. Results: Aa, Tf, Pg, Pg (fimA) gene and Td were detected in 0%, 31.4%, 45.1% 39.2% and 51% of atherosclerotic plaque samples, respectively. Tf was detected in 19.6%, Pg in 39.2%, Pg (fimA) gene in 33.3% and Td in 35.3% of both, subgingival plaque and atherosclerotic plaque samples. Thus, it is essential to investigate the subgingival plaque biofilm microbiota in patients receiving CAT using 16S rRNA gene sequencing. In this study, we conducted a preliminary investigation of the microbial community changes and its association with clinical characteristic at the early stage of CAT.
