Dental plaque is a biofilm that attaches to tooth surfaces, restorations and prosthetic appliances (including dentures and bridges) if left undisturbed.Understanding the formation, composition and characteristics of plaque helps in its control. [6]
The non-specific plaque hypothesis was developed in the nineteenth century, and postulates that the accumulation of activity of all types of dental plaque is responsible for oral disease, regardless of the virulence of the specific pathogens involved. Technological developments in the twentieth century enabled scientists to analyse the chemical ...
Periodontal pocketing < 3mm, but calculus (dental) present with or without plaque retentive factors such as "overhanging" restorations 3: Shallow periodontal pockets (i.e. first band on probe partially visible) 4: Deep periodontal pockets > 5.5 mm (first band on probe disappears) * (star added to the score, e.g. 4*)
Typically, dental hygienists (or dentists) use special instruments to clean (debride) teeth below the gumline and disrupt any plaque growing below the gumline. This is a standard treatment to prevent any further progress of established periodontitis.
The amount of bacteria is often indicated by the level of dental plaque. [27] This feature implies that when aggressive periodontitis is present, loss of attachment and bone loss tend to occur even if the plaque level is low. High levels of Aggregatibacter (or Actinobacillus) actinomycetemcomitans and, in some populations, Porphyromonas ...
The primary aetiological factor for periodontal disease is plaque biofilm of dental biofilm. A dental biofilm is a community of microorganisms attached to a hard, non-shedding surface. In the oral cavity, hard non-shedding surfaces include teeth, dental restorative materials and fixed or removable dental appliance such dentures. [15]
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 ...
Dental plaque, the precursor of periodontal disease, is a complex biofilm consisting mainly of bacteria, but also archaea, protozoa, fungi and viruses. Viruses that specifically infect bacteria—bacteriophages—are most common in the oral cavity. Viral roles in the progression of periodontal disease as of 2017 remains poorly explored.
