Exosome as bioactive nanovesicle for diagnostic and therapeutic applications in periodontitis

BMEMat, EarlyView.
This review introduces the mechanism that exosomes participate in the pathogenesis of periodontitis and their potential as biomarkers for early diagnosis and summarizes the application of cell‐ or plant‐derived exosomes or engineered exosomes in periodontitis or periodontal regeneration while proposing the perspective of translational application of ...

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 ...

Cryo-electron Tomography Elucidates the Molecular Architecture of \u3ci\u3eTreponema pallidum\u3c/i\u3e, the Syphilis Spirochete [PDF]

, 2009
Cryo-electron tomography (CET) was used to examine the native cellular organization of Treponema pallidum, the syphilis spirochete. T. pallidum cells appeared to form flat waves, did not contain an outer coat and, except for bulges over the basal bodies ...

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.

Periodontitis treatment and microbiome in a patient with FAM20A mutation: Case study of 1.5 years

Clinical Advances in Periodontics, EarlyView.
Abstract Background Enamel‐renal‐gingival syndrome (ERGS) is an autosomal recessive disorder caused by mutations in the FAMily with sequence similarity 20A (FAM20A) gene, and is characterized by amelogenesis imperfecta, delayed or failed tooth eruption, and periodontitis.

Treponema denticola transcriptional profiles in serum-restricted conditions [PDF]

FEMS Microbiology Letters, 2018
Treponema denticola is a major pathogen in periodontal disease and is frequently isolated from the lesions of patients with chronic periodontitis. Treponema denticola utilizes serum components as nutrient sources so as to colonize and proliferate in the gingival crevice. However, the mechanisms of serum utilization remain unclear. Therefore, the aim of

Does timing of systemic antibiotics influence periodontal treatment outcomes? A randomized clinical trial

Journal of Periodontology, EarlyView.
Abstract Background The aim of this study is to determine whether the timing of metronidazole (MTZ) and amoxicillin (AMX) administration, relative to scaling and root planing (SRP), influences the clinical and microbiological outcomes of periodontal treatment.

Porphyromonas gingivalis and Treponema denticola Mixed Microbial Infection in a Rat Model of Periodontal Disease

Interdisciplinary Perspectives on Infectious Diseases, 2010
Porphyromonas gingivalis and Treponema denticola are periodontal pathogens that express virulence factors associated with the pathogenesis of periodontitis. In this paper we tested the hypothesis that P. gingivalis and T.

Treponema denticola in Disseminating Endodontic Infections [PDF]

, 2006
Treponema denticola is a consensus periodontal pathogen that has recently been associated with endodontic pathology. In this study, the effect of mono-infection of the dental pulp with T.

Treponema denticola invasion into human gingival epithelial cells [PDF]

Microbial Pathogenesis, 2016
Host cell invasion is important for periodontal pathogens in evading host defenses and spreading into deeper areas of the periodontal tissue. Treponema denticola has been implicated in a number of potentially pathogenic processes, including periodontal tissue penetration. Here we tested the ability of T.
