BANA-positive plaque samples are associated with oral hygiene practices and not CD4+ T cell counts in HIV-positive patients [PDF]

, 2012
Background. The “red complex” microorganisms, namely, Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia are considered as potential pathogens causing HIV-associated periodontal diseases.

Matrix Metalloproteinases in Periodontal and Peri‐Implant Diseases: Contribution to Their Pathogenesis, Diagnosis, and Treatment

Journal of Periodontal Research, EarlyView.
This graphical abstract illustrates the role of matrix metalloproteinases (MMPs) across the pathogenesis, diagnosis, and therapeutics of periodontal and peri‐implant diseases. Microbial and host stimuli trigger MMP activation leading to extracellular matrix breakdown, point‐of‐care aMMP‐8 detection aids diagnosis, and adjunctive or AI‐assisted ...

Nisin bacteriocin blocks T. denticola-triggered MMP2 activation and pathogen internalization via TLR2

Scientific Reports
We examined Treponema denticola-induced dysregulation of toll-like receptor (TLR) signaling and its downstream effects on matrix metalloproteinase 2 (MMP2) expression and activation in periodontal cells, and whether the antimicrobial peptide nisin could ...

Salivary bacterial leakage into implant-abutment connections: preliminary results of an in vitro study [PDF]

, 2016
OBJECTIVE: The occurrence of bacterial leakage in the internal surface of implants, through implant-abutment interface (IAI), is one of the parameters for analyzing the fabrication quality of the connections. The aim of this in vitro study is to evaluate

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 ...

The Effect of Locally Delivered Doxycycline in the Treatment of Chronic Periodontitis. A Clinical and Microbiological Cohort Study [PDF]

, 2010
Objectives: To evaluate the efficacy of locally delivered doxycycline as an adjunct to non-surgical treatment with the use of an ultrasonic device compared to scaling and root planing using hand instruments, by means of clinical and microbiological ...

Peri‐Implantitis and Periodontitis: Biological Convergence, Contextual Divergence

Journal of Periodontal Research, EarlyView.
Periodontal and peri‐implant tissues differ and coincide in many aspects, from the clinical and radiological perspective, including histology, microbiology, and molecular markers. Thus, health and disease may also follow different and similar routes.
