Microbial Communities in the Extraradicular and Intraradicular Infections Associated With Persistent Apical Periodontitis

Frontiers in Cellular and Infection Microbiology, 2022
Microorganisms in the complex root canal system and the extraradicular regions, including the periapical lesions and extraradicular biofilm may cause root canal treatment failures.

Stem Cells and Androgen Receptor in Human Periapical Periodontitis [PDF]

International Journal of Morphology, 2011
La activacion de los macrofagos en los granulomas periapicales humanos se producen a traves de la presencia de citoquinas, endotoxinas y otros factores geneticos y epigeneticos que permiten la iniciacion de la inflamacion y la reabsorcion osea. El presente estudio pretende analizar la presencia de proteina CD133 (marcador de celulas madre) y de la ...

Factors associated with the prevalence of apical periodontitis: An observational study [PDF]

Revista Portuguesa de Estomatologia, Medicina Dentária e Cirurgia Maxilofacial
Objectives: Apical periodontitis is a lesion of endodontic origin caused by an immune response to necrotic and infected dental pulp. Since apical periodontitis can persist after endodontic treatment, radiographic diagnosis is crucial.

Presence of langerhans cells, regulatory T cells (Treg) and mast cells in asymptomatic apical periodontitis [PDF]

Brazilian Oral Research, 2020
Asymptomatic Apical Periodontitis is essentially an inflammatory disease of microbial aetiology. Association and function of the cell components involved, or specific inductive factors and growth mediators associated with development, maintenance and ...

Targeting neutrophil extracellular traps in metabolic and immune niche: Nanomaterials for diabetes tissue regeneration

BMEMat, EarlyView.
The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.

Pro-Inflammatory Cytokine TNF-α Attenuates BMP9-Induced Osteo/ Odontoblastic Differentiation of the Stem Cells of Dental Apical Papilla (SCAPs)

Cellular Physiology and Biochemistry, 2017
Background/Aims: Periapical periodontitis is a common oral disease caused by bacterial invasion of the tooth pulp, which usually leads to local release of pro-inflammatory cytokines and osteolytic lesion.

Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

Apical periodontitis: preliminary assessment of microbiota by 16S rRNA high throughput amplicon target sequencing

BMC Oral Health, 2018
Background Apical periodontitis includes periapical granulomas and radicular cysts, which are histologically distinguished by the absence and the presence of an epithelial lining, respectively.
