Molar–Incisor and Generalized Grade C Periodontitis: Distinct Microbiome–Immune Interactions Suggest Divergent Pathogenesis

Journal of Periodontal Research, EarlyView.
Molar–Incisor (PerioC‐MIP) and Generalized (PerioC‐G) Grade C Periodontitis in systemically healthy patients exhibit different microbiological, inflammatory markers, and genomic signatures, as the analysis of subgingival content from North Americans with PerioC‐MIP and Brazilians with PerioC‐G (geographic preference of each respective phenotype ...

A Multifunctional β‐Defensin‐3 Mimetic Peptide Modulates Host–Biofilm Interactions and Reduces Bone Loss in Periodontitis

Journal of Periodontal Research, EarlyView.
BDMP, a peptide that can penetrate cells and tissues, offering antimicrobial and anti‐inflammatory effects, has been identified as a potential new therapy for periodontitis. ABSTRACT Aim This study evaluated the potential of a beta‐defensin‐3 mimetic peptide (BDMP), a synthetic cell‐penetrating peptide with antimicrobial and immunomodulatory properties,

A randomized clinical trial about presence of pathogenic microflora and risk of peri-implantitis: comparison of two different types of implant-abutment connections [PDF]

, 2017
OBJECTIVE: The aim of this in vivo study was to evaluate two different types of implant-abutment connections: screwed connection and cemented connection, analyzing peri-implant bacteria microflora as well as other clinical parameters.

Bacteriophage and their potential roles in the human oral cavity. [PDF]

, 2015
The human oral cavity provides the perfect portal of entry for viruses and bacteria in the environment to access new hosts. Hence, the oral cavity is one of the most densely populated habitats of the human body containing some 6 billion bacteria and ...

Porphyromonas gingivalis GroEL exacerbates orthotopic allograft transplantation vasculopathy via impairment of endothelial cell function

Molecular Oral Microbiology, EarlyView.
Abstract Orthotopic allograft transplantation (OAT) is a significant approach to addressing organ failure. However, persistent immune responses to the allograft affect chronic rejection, which induces OAT vasculopathy (OATV) and organ failure. Porphyromonas gingivalis can infiltrate remote organs via the bloodstream, thereby intensifying the severity ...

The Outcome of Intracellular Selenomonas sputigena and its Impact on Gingival Keratinocytes

Molecular Oral Microbiology, EarlyView.
ABSTRACT Selenomonas sputigena is an understudied oral pathobiont associated with periodontitis and dental caries. We recently demonstrated that S. sputigena binds to gingival epithelial cells (GECs), where afterwards the bacterium causes robust in vitro pro‐inflammatory cytokine production and migration of monocytes and neutrophils.

Aggregatibacter Actinomycetemcomitans: Clinical Significance of a Pathobiont Subjected to Ample Changes in Classification and Nomenclature

Pathogens, 2019
Aggregatibacter actinomycetemcomitans is a Gram-negative bacterium that is part of the oral microbiota. The aggregative nature of this pathogen or pathobiont is crucial to its involvement in human disease.

Apoptotic Effects of the B Subunit of Bacterial Cytolethal Distending Toxin on the A549 Lung Cancer Cell Line [PDF]

, 2016
Cytolethal distending toxin (CDT) is a secreted tripartite genotoxin produced by many pathogenic gram-negative bacteria. It is composed of three subunits, CdtA, CdtB and CdtC, and CdtB-associated deoxyribonuclease (DNase) activity is essential for the ...

Role of antimicrobial photodynamic therapy (aPDT) and systemic resveratrol on immediate implant placement in type 2 diabetic rats

Photochemistry and Photobiology, EarlyView.
This study evaluated the combined effects of antimicrobial photodynamic therapy (aPDT) and systemic resveratrol on bone repair around immediately placed implants in type 2 diabetic rats. Resveratrol improved glycemic control and body weight, while aPDT increased implant stability and bone mineralization.

Aggregatibacter (Actinobacillus) Actinomycetemcomitans y Enfermedad Periodontal

Revista de la Facultad de Odontología, 2011
La enfermedad periodontal ha sido asociada siempre al biofilm o placa dental. El mismo está compuesto por microorganismos taxonómicamente diversos y se localiza principalmente, en el surco gingival. Su composición es tan compleja, que la mayoría de las bacterias comensales de la cavidad bucal están presentes.
