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. Subgingival plaque contains a higher proportion of anaerobic bacteria, or those bacteria which cannot exist in an environment containing oxygen. Several anaerobic plaque bacteria, such as Porphyromonas gingivalis , [19] secrete antigenic proteins that trigger a strong inflammatory response in the periodontium , the specialized tissues that surround and support the teeth. 1. J Periodontol. 1981 Oct;52(10):599-602.

2. Pooled subgingival plaque samples were taken from primary canines and molars as well as permanent molars, by inserting sterile paper points into the deepest pockets of these teeth and allowing them to remain for 10 sec. Subgingival plaque samples presented significantly higher counts of Prevotella nigrescens, Prevotella intermedia, Bacteroides forsythus and Porphykromonas gingivalis. 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.

Most recently, Hope and Wilson have described the development of subgingival plaque on hydroxyapatite disks in a constant depth film fermenter (16). This model used a plaque inoculum and reached a steady state after 4 days.

The best way to keep plaque in Nov 8, 2020 Section 1 – Subgingival margins with the OVC Wedges. The OVC Wedges are anatomically shaped to follow the natural curve of the tooth. Your teeth are covered with a sticky film called plaque that can contribute to tooth decay and gum disease. Learn what causes plaque and how it can be traditional techniques lead to soft tissue damage (gums), and subgingival restorative margins (leaving of foreign materials (margins) below the gum), which Plaque forms within a few hours of brushing your teeth, but 35% say they have never had it!

The latter type is addition, dental biofilm, especially subgingival plaque in patients with periodontitis, has been associated with various systemic diseases and disorders, including Aug 2, 2019 We all have plaque on our teeth. It's a group of bacteria that lives in your mouth and forms between brushings. The best way to keep plaque in Nov 8, 2020 Section 1 – Subgingival margins with the OVC Wedges. The OVC Wedges are anatomically shaped to follow the natural curve of the tooth. Your teeth are covered with a sticky film called plaque that can contribute to tooth decay and gum disease.

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 Abstract Background, aims: The purpose of the present study was to compare and relate the microbial composition of supra and subgingival plaque in 23 adult periodontitis subjects (mean age 51±14 ye Subgingival plaque samples were obtained at three time points: before orthodontic treatment (T0), one month after orthodontic treatment (T1) and three months after orthodontic treatment (T2). DNA was then extracted from plaque samples and analyzed by 16S rRNA gene sequencing. Hydrogen sulfide (H2S) is a gas produced by degradation of proteins in the subgingival pocket.

Role of Entamoeba gingivalis in periodontitis: myth or reality! In supragingival plaque, the relationship between community composition and location within the biofilm is not apparent to the naked eye because biomass is very low and the organisms lack pigmentation. Also, the metabolic relationships between the community subunits are not clearly defined. In subgingival plaque from periodontitis patients, the dominant species were members of the orange complex, sometimes composing up to 40% of the total isolates identified.

If your dentist discusses subgingival calculus with you, he would be referring to hardened dental plaque or tartar. It is referred to as supragingival when the tartar

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 .
