The more subgingival biofilm/plaque that accumulates on the teeth the more likely a patient will develop gingivitis. Gingivitis does NOT occur following any specific pathogen being present in the dental biofilm/plaque. More anaerobic Gram negative rod-shaped bacteria and spirochetes are present in the subgingival biofilm/plaque when compared to supragingival biofilm/plaque.

Subgingival plaque samples were collected and pooled from 4 non-adjacent proximal sites demonstrating at least 6 mm of attachment loss and 5 mm of probe depths. We collected samples by inserting 15 sterile endodontic paper-points (Caulk-Dentsply, Milford, DE, USA) into the pockets for 10 sec, following isolation and supragingival plaque removal.

However, it seems necessary to assess variations in subgingival plaque caused by orthodontic appliances. The aim of this study was to investigate changes in 2021-01-15 Pooled subgingival plaque samples were collected and analyzed for detection of bacteria and viruses using loop‐mediated isothermal amplification. Prevalence of subgingival A. actinomycetemcomitans , HCMV, and P. gingivalis were significantly higher among aggressive periodontitis patients than periodontally healthy controls. 2011-08-10 2017-01-16 Although the initial subgingival plaque community of each subject was unique in terms of diversity and composition, 10 common key species were found in the 6 Chinese individuals.

Tooth brushing twice daily to reduce oral debris and dental plaque remains the mainstay of oral health, and gingivitis may serve as a portal for infection and further result in subgingival inflammation and  15 dec.

Subjects will have up to 10 sites identified as "sampling sites" that will have supragingival plaque, subgingival plaque, and gingival crevicular fluid (GCF) collected 

Subgingival samples exhibited a significantly higher proportion of “red” and “orange complex” species, while supragingival plaque exhibited higher proportions of “green” and “purple” complex species as well as 2017-11-01 2017-02-03 Sample Collection and Processing. Subgingival plaque samples were collected 1 week after the full-mouth periodontal examination (Feng et al., 2015). All participants were requested to refrain from food for 8 h and oral hygiene (brushing or flossing the teeth) for 12 h before sampling.

Subgingival plaque collection

subgingival plaque can be successfully cultured, but the deeper layer may be missed [10]. In comparison, curettes can collect subgingival plaque from the entire periodontal pocket, but the active periodontal pathogens in the outer layer of the plaque can be underestimated with this method [11].

traditional techniques lead to soft tissue damage (gums), and subgingival restorative margins (leaving of foreign materials (margins) below the gum), which  

Plaque sample collection and DNA extraction were conducted as specified in reference 27. Libraries were prepared using the NEBNext Illumina DNA library preparation kit according to manufacturer’s specifications (New England Biolabs, Ipswich, MA). Microorganism isolates from subgingival plaque sites: Paolantonio et al. 1999: Selfcontrolled study: 24: 18–22y: 16/26/12/22 or 32/42/36/46: Lateral incisor (bracket) Molar (band) Before Subgingival plaque samples were obtained from ten individuals at least 70 years old who participated in a study to assess oral health and cognitive function. DNA was isolated from the samples and a gene segment from the V3 portion of the 16S bacterial ribosomal RNA gene was amplified and sequenced using an Illumina HiSeq1000 DNA sequencer. De novo subgingival plaque formation The introduction of oral implants especially a two stage type, provides a new experimental setup.

The purpose of this study was to assess the association between a panel of putative periodontal bacterial pathogens and chronic periodontitis among Yemenis. Subgingival DNA samples were obtained from diseased and healthy sites of 20 non-smoking, moderate to severe Following the collection of baselines GCF samples and plaque samples, oral prophylaxis was carried out by the same examiner in both groups. In Group I, chlorhexidine (0.12%) gel was applied over the gingiva once in two weeks for 3 months. Abstract. Background There are many studies documenting increased prevalence of periodontal infection in women with preeclampsia.
