Treponema Denticola


  • CONCLUSIONS: In the present study, pregnant women with periodontal disease presented an association in the placental tissue between the presence of T. denticola and P. gingivalis and hypertensive disorders.[ncbi.nlm.nih.gov]
  • Other species, including S. oralis, Eikenella corrodens, S. intermedius and F. nucleatum ssp. vincentii, were associated with disease when P. gingivalis and T. forsythia were present in low proportions.[ncbi.nlm.nih.gov]
  • Based on the data presented here, we hypothesize that the primary function of FHL-1 binding by T. denticola might be to facilitate adherence to FHL-1 present on anchorage-dependent cells and in the extracellular matrix.[ncbi.nlm.nih.gov]
  • T. denticola was present at significantly elevated levels in plaque samples collected from deep-pocket sites of patients with severe periodontitis relative to the healthy controls and a group with moderate disease.[ncbi.nlm.nih.gov]

  • STUDY DESIGN: Microbial samples were collected by aspiration from 32 cases diagnosed as acute periradicular abscess. DNA was extracted from the samples by using a QIAamp DNA mini-kit and analyzed with real-time PCR.[ncbi.nlm.nih.gov]
  • The fibroblast medium was aspirated and was replaced by the P. micros suspension. After a 24-h incubation (37 C, 5% CO 2 ), the culture medium supernatants were collected and were stored at 20 C until used.[tandfonline.com]

Skin Lesion
  • Treponema denticola is part of the human oral microbiota and is associated with periodontitis while T. pedis has been isolated from skin lesions in animals, e.g., digital dermatitis in cattle and necrotic ulcers in pigs.[ncbi.nlm.nih.gov]
  • Calculus was removed in as large pieces as possible by the use of a sickle or a push scaler placed underneath the apical or facial border of the calculus and fracturing it from the tooth surface in a single stroke.[ncbi.nlm.nih.gov]
  • It has been suggested that some bacteria mask their surfaces with serum proteins.[ncbi.nlm.nih.gov]
  • The chymotrypsin-like protease, dentilisin (PrtP), has been suggested to be an important virulence factor of T. denticola.[ncbi.nlm.nih.gov]
  • This data suggested that the antigenic variability found in to the MSP molecule, may be an important factor involved in immune evasion by T. denticola.[ncbi.nlm.nih.gov]
  • These results suggest that inappropriate expression of FlaB2 and FlaB3 caused the unusual elongation of flagella that resulted in decreased motility.[ncbi.nlm.nih.gov]
  • Recent studies suggest that the tip-oriented adhesion of Treponema denticola is a consequence of polar clustering of its adhesins on contact with the substratum and is compatible with viability.[ncbi.nlm.nih.gov]


  • Additionally, F. alocis and T. forsythia were detected more frequently in teeth with necrotic pulp than in teeth with failing endodontic treatment.[ncbi.nlm.nih.gov]
  • MATERIAL AND METHODS: The study was conducted on 25 alcoholics from the Department of Alcohol Addiction Closed Treatment and 25 non-alcoholic patients from the Department of Periodontology, Wroclaw Medical University.[ncbi.nlm.nih.gov]
  • Treatment involves extensive antibiotic treatment and complex surgery. See also Oral microbiology Periodontitis References nl:Treponema denticola[wikidoc.org]
  • Heat treatment of the serum to inactivate complement confirmed that killing was mediated by complement. These results indicate that the FH-FhbB interaction is required for serum resistance whereas dentilisin is not.[ncbi.nlm.nih.gov]
  • However, qualitative analysis is insufficient for the clinical evaluation of periodontal treatments, and quantification of T. denticola populations is essential for monitoring therapeutic efficacy.[ncbi.nlm.nih.gov]


  • However, it is clear that the prognosis for periodontal health after dental treatment is much better for patients whose blood sugar levels are well controlled.[herenciageneticayenfermedad.blogspot.com]

  • While the majority of people will not require the preventative treatment being proposed, those at high risk of oral infections would make the ideal candidates for this new inhibitor and preventing the cooperation of bacteria could mean vastly reduced[smileaustin.com]
  • TDE0471 protects T.denticola from serum killing by preventing the deposition of membrane attack complexes on the bacterial cell surface.[ncbi.nlm.nih.gov]
  • Moreover, in vivo, saliva inhibits dentilisin, thus preventing LL-37 restriction and ensuring its bactericidal and immunoregulatory activities.[ncbi.nlm.nih.gov]
