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. 2019-12-01 Plaque Biofilms The recent recognition that subgingival plaque is a biofilm helps considerably in understanding its persistence and resistance to the host's defense system.

In the total absence of oral hygiene, plaque formation and an initial host defensive response within gingival tissue oc-cur. With optimum—including interdental—oral hygiene, the formation of biofilm is repeatedly disrupted and gingi-val health is maintained. 45 One-week-old Plaque— The removal of biofilm deposits from within the periodontal pocket is recognized as being fundamental in reducing bacterial burden and down regulating the pro-inflammatory response in the treatment of the periodontal diseases.

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. Subgingival plaque soft tissue destruction developing plaque biofilm. Polysaccharides produced by bacteria , of which dextran is the predominant form, contribute to the organic portion of the matrix.

The inhibition effects of BGA against biofilm formation by these plaque bacteria were evaluated. Of 12 samples, the biofilm formation by eleven was significantly attenuated by 128 to 256 μg/mL of BGA. 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

Thus, it is essential to investigate the subgingival plaque biofilm microbiota in patients receiving CAT using 16S rRNA gene sequencing.
