Oral Biofilm Sampling for Microbiome Analysis in Healthy

WFRF:Persson R. - SwePub - sökning

T he purpose of the present study was to find out to what extent subgingival plaque formation may be prevented by toothbrushing. The experiment was carried out on a total of 28 molars in four monkeys. On day 0 all supra‐ and subgingival deposits were removed, and during the following year, the teeth on the left side were carefully brushed three the subgingival area (gingivitis, gingival pocket formation). 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— Subgingival biofilm is plaque that is located under the gums. It occurs after the formation of the supragingival biofilm by a downward growth of the bacteria from above the gums to below.

Subgingival plaque and serum samples were collected from study participants before (baseline) and 90 days after treatment to analyse the abundance of specific bacteria and evaluate anti-bacterial antibodies, C-reactive protein (CRP), tumour necrosis factor α (TNF-α), interleukin 6 (IL-6) and ACPA in serum. 2021-01-13 · Subgingival plaques were collected from 40 Research found that exposure to tobacco in cigarettes smokers has promoted the formation of a dual species biofilm composed of both S. gordonii Subgingival plaque samples were collected from 6–12 periodontal pockets from each subject by using Hartzell R-1, R-2 curettes.

Dental plaque is composed primarily of microorganisms (Bacteria & Fungi, a small number of viruses). Supragingival plaque biofilm forms in sites that are protected from the normal cleansing action of the tongue, cheek, and lips. This includes surfaces along the gingival margin of the tooth and the occlusal pits and fissures. Subgingival plaque biofilm can only be seen when it is removed from the pocket with an instrument. We observed recently that strains of Fusobacterium nucleatum also interacted with S. sanguis to form corncobs.

The Clinical studies have shown that the gingiva surrounding natural teeth has the potential to prevent subgingival biofilm formation and to respond to early biofilm accumulation (Berglundh et al., 1992). Protective mechanisms include structural components, such as a well-keratinized oral epithelium (Berglundh et al., 1991). subgingival plaque microbiome, and explore any associations between these parameters in a cohort of patients with PD. Patients with PD only, rather than PD and RA, were chosen to avoid the confounding factors associated with RA-related treatments. For the subgingival environment, with more facilities for microorganisms to survive, the importance of surface characteristics dramatically decreases. However, the influence of surface roughness and surface‐free energy on supragingival plaque justifies the demand for smooth surfaces with a low surface‐free energy in order to minimise plaque formation, thereby reducing the occurrence of caries and periodontitis.

It occurs after the formation of the supragingival biofilm by a downward growth of the bacteria from above the gums to below. This plaque is mostly made up of anaerobic bacteria, meaning that these bacteria will only survive if there is no oxygen. Supragingival calculus formation is most abundant on the buccal (cheek) surfaces of the maxillary (upper jaw) molars and on the lingual (tongue) surfaces of the mandibular (lower jaw) incisors. These areas experience high salivary flow because of their proximity to the parotid and sublingual salivary glands. The purpose of this study was to investigate the mode of subgingival plaque formation and its association with various microflora in the thoroughly debrided periodontal pocket by scanning electronmicroscopy.
