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— Plaque initiates gingival inflammation, which leads to pocket formation, and the pocket in turn provides a sheltered area for plaque and bacterial accumulation.

Subgingival plaque formation

The unattached subgingival plaque is more closely associated with the wall of the 14 May 2020 dental plaque is formed 24 hours after tooth brushing.. dental plaque is growth and colonization of micro organism.this video addition, dental biofilm, especially subgingival plaque in patients with periodontitis, Biofilm formation begins with the adherence of bacteria to a tooth surface, In dentistry, calculus or tartar is a form of hardened dental plaque. hardened surface that is formed provides an ideal surface for further plaque formation. the teeth and the gingiva, where it is referred to as subgingival (" Illustration about Biofilm formation on a molar tooth, covering the enamel and deep to the subgingival crown root junction. Created in Adobe Illustrator. EPS 10. Biofilms formed on the tooth surface is called as dental plaque.

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 …

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 ). Initial plaque formation takes place along the gingival margin & from interdental space, later further extension in coronal direction can be observed.

• 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.

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.

When plaque builds up in your mouth, it can turn into an even greater dental health threat: calculus. This formation, also known as tartar, is a calcified mass that adheres to your teeth. Calculus is classified as either supragingival or subgingival, depending on its location on your teeth.

Counts of 40 subgingival spe- cies wore determined in each plaque sample using the checkerboard DNA-DNA hybridization technique (Socran-sky et al. I994).

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 subgingival matrix of plaque biofilm contains blood products associated with subgingival hemorrhage. These matrix products have a dark pigment and differ from supragingival calculus, where the organic matrix components come primarily from saliva and do not contain blood.
