Subgingival plaque biofilm phase

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. The formation of biofilms by subgingival bacteria provides the bacteria with an advantage that permits long-term survival within the sulcus or pocket environment. 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.). IN SUBGINGIVAL BIOFILM OF BANDED AND BONDED MOLARS IN EARLY PHASE OF FIXED ORTHODONTIC TREATMENT KRISZTINA MÁRTHA1, LILLA LŐRINCZI2*, CRISTINA BICĂ3, RÉKA GYERGYAY3, BLANKA PETCU4, LUMINIȚA LAZĂR5 1Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy, Tirgu Mures Keywords: biofilm, glycine, periodontal disease INTRODUCTION The Glossary of Periodontal Terms (2001, 4th edition) defines periodontitis as “inflammation of the supporting tissues of teeth”.

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.

Periodontitis is associated with an increase in the levels and proportions of specific bacteria in the teeth supporting tissues, related not only to the amount of biofilm, but mainly to its composition, as some bacteria are capable of altering the subgingival ecosystem, allowing the colonization of other more virulent microorganisms promoting the generation of an increasingly complex biofilm. Thus, subgingival plaque present in periodontitis lesions is qualitatively distinct from plaque

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. The formation of biofilms by subgingival bacteria provides the bacteria with an advantage that permits long-term survival within the sulcus or pocket environment.

Environmental effects on oral biofilm communities. the outgrowth of low abundance disease-associated species from biofilms taken from healthy sites and need to undergo a phase of stabilization in order to be remembered in the long-term. with shifts in the balance of the microbial composition of subgingival biofilms.

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). subgingival instrumentation (scaling and root planing) is performed to remove the causative bacteria, plaque and biofilm (phase I). Reevaluation after this first caus-ative treatment will decide on the need for repeated or follow-up treatments like surgery (phase II) or support-ive treatments (phase III ).

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) .

What dental biofilm phase is this Space between layers provide an anaerobic environment 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.

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.

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. Dental plaque biofilm accumulates on the surface of teeth and can be visible in the oral cavity (supragingival plaque) or extends apical to the gingival margin (subgingival plaque).
