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.

An acquired pellicle is a layer of saliva that is composed of mainly glycoproteins and forms shortly after cleaning of the teeth or 2021-01-13 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.

Subgingival plaque formation

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. The subgingival plaque differs from supragingival plaque, in that it contains many large filaments with flagella and is rich in Spirochetes. Tooth-associated plaque is similar to supragingival plaque; whereas tissue- associated plaque is covered with flagellated bacteria without a well-defined extracellular matrix and numerous bristle— brush formations. Plaque initiates gingival inflammation, which leads to pocket formation, and the pocket in turn provides a sheltered area for plaque and bacterial accumulation. The increased flow of gingival fluid associated with gingival inflammation provides the minerals that mineralize the continually accumulating plaque that results in the formation of subgingival calculus ( Figure 7-13 ). General illness can also contribute to the formation of subgingival calculus – impaired metabolism, abnormalities in the internal organs.

 Oral implants have been used as a model to study the impact of surface roughness on subgingival plaque formation, smooth abutments (avg roughness < 0.2µm) were found to harbour 25 times less bacteria than the rough ones, with a higher density of coccoid cells. Plaque formation at ultrastructural level. Pellicle.

High-energy surfaces collect more plaque, bind the plaque more strongly, and select specific bacteria. 12 Although these factors interact, surface roughness is more important than surface-free energy. 10,13 Alternatively, subgingival plaque formation is influenced by other conditions such as a favorable environment for bacterial growth, making surface characteristics (roughness and energy subgingival microflora is that professional and personal plaque control is not strictly limited to the supragingival environment. When aimed at treating periodontal diseases, these procedures are 2009-04-01 1994-03-14 Formation of Dental Plaque • Dental plaque may be readily visualized on teeth after 1 to 2 days with no oral hygiene measures. Plaque is white, grayish, or yellow and has a globular appearance. • Movement of tissues and food materials over the teeth results in mechanical removal of plaque on the coronal two thirds of the tooth surface. Plaque absorbs calcium and phosphate from saliva for the formation of supragingival calculus and from crevicular fluid for the formation of subgingival calculus.

Supragingival and tooth associated subgingival plaque→calculus formation. Tissue associated subgingival plaque→periodontal Subgingival calculus forms directly below the gumline and is typically darker in Calculus is bad for gingival health as it results in additional plaque formation. The processes of the formation of calculus from dental plaque is not well Subgingival calculus forms just below the gumline and is usually dark in color from 2 Jan 2017 Dental plaque can be formed below as well as above the gum, while Subgingival plaque is found below the gum and it is not easily visible. 30 May 2019 It is hypothesized that cornstarch acts as a slow release of glucose, which aids in the formation of biofilms over tooth surfaces.

None of the subjects had taken antibiotics or undergone scaling or root planing within the 6 months before the study. Plaque formation at ultrastructural level Pellicle A translucent, homogenous, thin, unstructured film covering and adherent to the surfaces of teeth, restorations, calculus, and other surfaces within the oral cavity Efficacy of two clorhexidine formulations to Control the Initial Subgingival Biofilm Formation assessed by the plaque free zone index. [ Time Frame: 24hours ] The presence of scores 0, 1 or 2 of the index "Plaque Free Zone" will be recorded at baseline and at each 24 hours, during a period of 96 hours (4 days). Subgingival plaque samples were taken from the mesio-buccal aspect of each tooth in each subject at each monitor-ing visit. Counts of 40 subgingival spe- cies wore determined in each plaque sample using the checkerboard DNA-DNA hybridization technique (Socran-sky et al.
