The use of lasers in treating periodontal disease has been seen by some dental professionals as controversial. [6] The American Academy of Periodontology stated in 1999 that it was "not aware of any randomized blinded controlled longitudinal clinical trials, cohort or longitudinal studies, or case-controlled studies indicating that 'laser excisional new attachment procedure (or Laser ENAP)' or ...
Chronic periodontitis is initiated by Gram-negative tooth-associated microbial biofilms that elicit a host response, which results in bone and soft tissue destruction. In response to endotoxin derived from periodontal pathogens, several osteoclast-related mediators target the destruction of alveolar bone and supporting connective tissue such as the periodontal ligament.
In 1890, W.D. Miller, considered the father of oral microbiology, was the first to associate pulpal disease with the presence of bacteria. [11] This was confirmed by Kakehashi, who, in 1965, proved that bacteria were the cause of pulpal and periradicular disease in studies using animal models; pulpal exposures were initiated in both normal and germ-free rats, and while no pathologic changes ...
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 ...
The inflammation pathway of periodontitis is such that as the infection grows, bacteria, including P. gingivalis are targeted by neutrophils and natural killer immune cells. These cells phagocytize the bacteria, while simultaneously cytokine molecules in the area lead to a proinflammatory
Aggressive periodontitis is often characterised by a rapid loss of periodontal attachment associated with highly pathogenic bacteria and an impaired immune response. Various studies have associated Aggregatibacter actinomycetemcomitans , formerly known as Actinobacillus actinomycetemcomitans , with aggressive periodontitis.
Dental amalgam used in fillings inhibits bacterial reproduction. [13] Organic mercury compounds have been used as topical disinfectants (thimerosal, nitromersol, and merbromin) and preservatives in medical preparations and grain products (both methyl and ethyl mercurials). Mercury was used in the treatment of syphilis.
Periodontal pathogens are bacteria that have been shown to significantly contribute to periodontitis. 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 ...
