Isolation and characterization of a plasmid fromTreponema denticola

FEMS Microbiology Letters, 1991
Agarose gel electrophoresis of whole genomic DNA of the oral spirochaete Treponema denticola has revealed a plasmid-like fraction. Purification and restriction enzyme analysis has confirmed the presence of a 2.6-kb circular plasmid, which has been mapped for restriction sites and cloned into the Escherichia coli plasmid pUC18. Southern blot analysis of

Etiology, pathogenesis and treatment of peri‐implantitis: A European perspective

Periodontology 2000, EarlyView.
Abstract Peri‐implantitis is a plaque‐associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri‐implant mucosa and progressive loss of supporting bone. Over the last 30 years, peri‐implantitis has become a major disease burden in dentistry.

An investigation of the presence of specific anaerobic species in necrotic primary teeth

Brazilian Oral Research, 2013
Different microbial identification methods have shown that the microbial community profiles in endodontic infections are diverse and assorted. The aim of this study was to evaluate the frequency of selected endodontic pathogens in the pulp chambers (PCs)

Characterization of a potential ABC-type bacteriocin exporter protein from Treponema denticola

BMC Oral Health, 2016
Treponema denticola is strongly associated with the development of periodontal disease. Both synergistic and antagonistic effects are observed among bacterial species in the process of biofilm formation.

Root surface biomodification in periodontal therapy: Biological rationale and clinical applications

Periodontology 2000, EarlyView.
Abstract Regenerative periodontal therapy aims to form new cementum, periodontal ligament, and alveolar bone, all sealed by gingival tissue. The root surface acts as the wound margin during this regeneration process. Root surface biomodification (root conditioning/root decontamination), therefore, seems instrumental in promoting surface decontamination

Mixed Red-Complex Bacterial Infection in Periodontitis

International Journal of Dentistry, 2013
The red complex, which includes Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia (formerly Bacteroides forsythus), are recognized as the most important pathogens in adult periodontal disease.

Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, and Treponema denticola / Prevotella intermedia Co-Infection Are Associated with Severe Periodontitis in a Thai Population

PLoS ONE, 2015
Periodontitis is a polymicrobial infection of tooth-supporting tissues. This cross-sectional study aimed to examine the associations between five target species and severe periodontitis in a Thai population. Using the CDC/AAP case definition, individuals

The oral microbiota and periodontal health in orthodontic patients

Periodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.
