Virulence Factors of the Oral Spirochete Treponema denticola [PDF]

Journal of Dental Research, 2010
There is compelling evidence that treponemes are involved in the etiology of several chronic diseases, including chronic periodontitis as well as other forms of periodontal disease. There are interesting parallels with other chronic diseases caused by treponemes that may indicate similar virulence characteristics.

Zinc‐stabilized stannous fluoride modulates the periodontal microbiome, reducing Fusobacteria, key Gram‐negative species, and overall inflammation within an experimental gingivitis clinical trial

Journal of Periodontology, EarlyView.
Abstract Background This study aimed to evaluate the effects of a dentifrice containing stannous fluoride stabilized with zinc phosphate on subgingival microbiome composition and clinical inflammation during experimental gingivitis, compared with a sodium fluoride control. Methods This investigation was conducted as a secondary analysis of a randomized,

The potential role of genus Treponema in carcinogenesis with a focus on oral squamous cell carcinoma: a scoping review of the evidence

BMC Oral Health
Background Current concepts suggest that a dysbiotic environment can promote ‘oral carcinomas.’ Microbiome studies on the oral cavity indicate changes in bacterial disposition in this condition.

Oral microbiome and homeostatic regulation of periodontal health: From dysbiosis to precision intervention

VIEW, EarlyView.
Periodontal homeostasis is maintained by coordinated interactions between the oral microbiome and host. Dysbiosis disrupts this ecological balance and contributes to periodontal disease, whereas multi‐omics, artificial intelligence, and microbiome‐based interventions provide emerging opportunities for precision diagnosis, ecological restoration, and ...

Prevalence of Treponemaspp. in endodontic retreatment-resistant periapical lesions

Brazilian Oral Research, 2015
This study investigated the presence of the Treponema species in longstanding endodontic retreatment-resistant lesions of teeth with apical periodontitis, the association of this species with clinical/radiographic features, and the association among the ...

Characterization of the Treponema denticola Virulence Factor Dentilisin [PDF]

, 2020
Treponema denticola is a potent periodontal pathogen that forms a red complex with Porphyromonas gingivalis and Tannerella forsythia. It has many virulence factors, yet there are only a few reports detailing these factors. Among them, dentilisin is a well-documented surface protease.
