Supragingival and Subgingival Plaque: Paradigm Biofilms Robert J. Palmer Jr, PhD March 2010 Issue - Expires March 31st, 2013 Compendium of Continuing Education in Dentistry

All positive samples derived from subgingival and gingival sulcus plaque containing between 10 3 and 5 × 10 5 cells ml −1 of plaque suspension, whereas saliva, smooth surface plaque and samples from the tongue or cheeks were negative.

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 Actinomyces species. Subgingival Plaque in Periodontal Health Antagonizes at Toll-Like Receptor 4 and Inhibits E-Selectin Expression on Endothelial Cells. Subgingival plaque was analyzed from healthy subjects and subjects with refractory periodontitis, adult periodontitis, human immunodeficiency virus periodontitis, and acute necrotizing ulcerative gingivitis. 16S ribosomal DNA (rDNA) bacterial genes from DNA isolated from subgingival plaque samples were PCR amplified with all-bacterial or selective primers and cloned into Escherichia coli. The purpose of the present investigation was to attempt to define such communities using data from large numbers of plaque samples and different clustering and ordination techniques. Subgingival plaque samples were taken from the mesial aspect of each tooth in 185 subjects (mean age 51 +/- 16 years) with (n = 160) or without (n = 25) periodontitis.

The collection of subgingival plaque samples is the common way for the determination of periodontopathic bacteria. However, recently, salivary analysis has been discussed as an advantageous future diagnostic method for periodontitis because it offers simple quantitative sampling and the possibility to assess various bacteria.

The effect of female sex hormones on subgingival plaque. Jensen J, Liljemark W, Bloomquist C. The periodontal status of three groups of women; pregnant, taking oral contraceptives, and nonpregnant, were evaluated clinically and microbiologically for changes in their gingiva and any corresponding changes in the subgingival microbial plaque For each subject, subgingival plaque was obtained from two chemically treated (test) and one non‐chemically treated (control) pockets at days 0 (prior to scaling and root planing), 7, 14, 21, 28, 56, and 84. The subgingival microflora was assessed using darkfield microscopy. Subgingival plaque samples were taken from the mesial aspect of each tooth in 185 subjects (mean age 51 ± 16 years) with (n = 160) or without (n = 25) periodontitis. The presence and levels of 40 subgingival taxa were determined in 13.261 plaque samples using whole genomic DNA probes and checkerboard DNA‐DNA hybridization. Define subgingival plaque.

Differential phase‐contrast microscopy showed a significant difference in plaque composition, especially when supragingival plaque was considered (P = 0.05). 37.

Supragingival plaque control is an effective method of controlling gingivitis and is an important component of periodontal therapy. To compare the clinical efficacy of commercially available dentifrice viz Parodontax [R], Parodontax [R] with scaling and scaling alone in patients with gingivitis: a randomized controlled clinical trial

Hydrogen sulfide (H2S) is a gas produced by degradation of proteins in the subgingival pocket. It is highly toxic and believed to have pro-inflammatory properties. We aimed to study H2S production from subgingival plaque samples in relation to disease severity in subjects with natural development of the disease, using a colorimetric method based on bismuth precipitation. Subgingival plaque was analyzed from healthy subjects and subjects with refractory periodontitis, adult periodontitis, human immunodeficiency virus periodontitis, and acute necrotizing ulcerative gingivitis. 16S ribosomal DNA (rDNA) bacterial genes from DNA isolated from subgingival plaque samples were PCR amplified with all-bacterial or selective primers and cloned into Escherichia coli .
