Subgingival plaque samples were obtained at three time points: before orthodontic treatment (T0), one month after orthodontic treatment (T1) and three months after orthodontic treatment (T2). 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 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 … 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 2018-01-02 Subgingival plaque samples were obtained at 18 weeks (T3) of therapy. To minimize the contamination, first the value of FMPS was determined, followed by collection of subgingival plaque samples and measurement of FMBS and PPD. All clinical measurements and both sample collections were performed by one calibrated and experienced investigator. 2019-07-31 The growth and development of biofilm are characterized by 4 stages: initial adherence, lag phase, rapid growth, and steady state. Biofilm formation begins with the adherence of bacteria to a tooth surf ace, followed by a lag phase in which changes in genetic expression (phenotypic shifts)occur.

Background This pilot study was part of a larger study which compared the effect of subgingival air-polishing using trehalose powder with sonic scaling on clinical parameters during supportive periodontal therapy. Within this microbiological part of the investigation subgingival samples were taken from 10 participants to analyze the survival of different bacterial species after the two

31 Dec 2017 Analysis of children's oral biofilm during different stages in life is thus an important theme in Bacterial Diversity in Human Subgingival Plaque.

However, plaque and calculus reflect different 2016-01-15 · Dental plaque biofilm is the community comprises bacterial micro-colonies, an extracellular slime layer, fluid channels, and a primitive communication system. Bacteria are the primary etiologic agents in periodontal disease. 4 The association of bacteria is not random; there are specific associations among bacterial species. 2017-02-03 · At baseline (T0), clinical parameters including gingival index, probing depth and sulcus bleeding index were tested, and subgingival plaque samples were collected from the lower incisors. The counts of A. actinomycetemcomitans, P. gingivalis, P. intermedia, T. forsythia and total bacteria were determined by real-time PCR. Porphyromonas gingivalis is a late-colonizing bacterium of the subgingival dental plaque biofilm associated with periodontitis. Two P. gingivalis genes, fimR and fimS , are predicted to encode a two-component signal transduction system comprising a response regulator (FimR) and a sensor histidine kinase (FimS).

The biofilm model described here closely reproduces the composition of the cultivable subgingival plaque both in the species present and in their relative proportions.

2019-07-26 · Subgingival Plaque Biofilm Structure and Periodontal Disease Development As described above, an understanding of the synergistic activities of subgingival microbes and the host as these communities undergo dysbiosis is emerging; however, what remains poorly understood is how these activities are distributed within the physical architecture of microbial communities [98] .
