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 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. MATERIALANDMETHODS Selectionofstudygroup 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. Assessment of Periodontopathogens in Subgingival Biofilm of Banded and Bonded Molars in Early Phase of Fixed Orthodontic Treatment. Mártha K(1), Lőrinczi L(2), Bică C(3), Gyergyay R(3), Petcu B(4), Lazăr L(5). Subgingival biofilm is plaque that is located under the gums.
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. Recolonization of the periodontal pocket by pathogenic bacteria, however, occurs within weeks of initial phase therapy making continuous and regular subgingival biofilm Fig. 11 shows the count (x10 5) of the DNA probes of the 40 species of microorganisms analyzed in the planktonic and biofilm phase in the subgingival plaque samples collected.

Extending apically from the supragingival region, a subgingival plaque biofilm will often form within the existing gingival sulcus/pocket; this was previously called the “adherent” plaque.
These subgingival plaques are structured communities of microorganisms with great phylogenetic diversity embedded in a self-produced extracellular polymeric matrix.

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. 2019-07-31 · The periodontal biofilm is constantly formed in the supragingival region, and if not removed within 2–4 days, the volume formed will cause this plaque to extend below the gingival margin and into the groove.

• Dental plaque can be defined as the soft deposits that form the biofilm adhering to the tooth surface or other hard surfaces in the oral cavity, including removable and fixed restorations. • Materia alba refers to soft accumulations of bacteria and tissue cells that lack the organized structure of De novo subgingival plaque formation The introduction of oral implants especially a two stage type, provides a new experimental setup. Oral implants have been used as a model to study the impact of surface roughness on subgingival plaque formation, smooth abutments ( avg roughness < 0.2µm) were found to harbour 25 times less bacteria than the rough ones, with a higher density of coccoid cells. 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.

Microbial clusters in subgingival biofilms Fusobacterium nucleatum. 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.).

This inflammation is a sequelae of accumulation of supragingival as well as subgingival plaque which is a type of pathogenic biofilm1. The biofilm 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.

load and decrease of inflammation. Hence, in the initial therapeutic phase, plaque and calculus are removed mechanically from supra- and subgingival dental surfaces by scaling and root planing with hand instruments or mechanical devices (e .g . curettes, ultrasonic scalers) . Additionally, patients are instructed to improve oral hygiene .
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.
