Dental plaque is considered a biofilm adhered to the tooth surface. It is a meticulously formed microbial community, that is organised to a particular structure and function. [ 12 ] Plaque is rich in species, given the fact that about 1000 different bacterial species have been recognised using modern techniques.
A dynamic equilibrium exists notably between the bacteria of dental plaque and the host's immune system, enabling the plaque to stay behind in the mouth when other biofilms are washed away. [19] In equilibrium, the bacterial biofilm produced by the fermentation of sugar in the mouth is quickly swept away by the saliva, except for dental plaque.
The ecological plaque hypothesis, a combination of the two previously mentioned hypotheses, suggests that there are certain species responsible for pathology, but are present in insufficient quantities to cause damage to a healthy individual. [13] Thus biofilm derived diseases are the result of an imbalance in the normal oral ecology. [14]
The dental pellicle, or acquired pellicle, is a protein film that forms on the surface enamel, dentin, artificial crowns, and bridges by selective binding of glycoproteins from saliva that prevents continuous deposition of salivary calcium phosphate.
Plaque and calculus deposits are a major etiological factor in the development and progression of oral disease. An important part of the scope of practice of a dental hygienist is the removal of plaque and calculus deposits. This is achieved through the use of specifically designed instruments for debridement of tooth surfaces.
Scaling and root planing, also known as conventional periodontal therapy, non-surgical periodontal therapy or deep cleaning, is a procedure involving removal of dental plaque and calculus (scaling or debridement) and then smoothing, or planing, of the (exposed) surfaces of the roots, removing cementum or dentine that is impregnated with calculus, toxins, or microorganisms, [1] the agents that ...
These can form a plaque that can lead to atherosclerosis and trigger myocardial infarction and stroke. [1] [2] [3] Foam cells are fat-laden cells with a M2 macrophage-like phenotype. They contain low density lipoproteins (LDL) and can be rapidly detected by examining a fatty plaque under a microscope after it is removed from the body. [4]
Periodontal disease typically arises from the development of plaque biofilm, which harbors harmful bacteria such as Porphyromonas gingivalis and Treponema denticola. These bacteria infect the gum tissue surrounding the teeth, leading to inflammation and, if left untreated, progressive damage to the teeth and gum tissue. [ 9 ]
