Human Atlas of Tooth Decay Progression: Identification of Cellular Mechanisms Driving the Switch from Dental Pulp Repair Toward Irreversible Pulpitis

Advanced Science, EarlyView.
Tooth decay progression transforms the dental pulp response from repair to fibrosis. At early stages, stromal cells reprogram to repair the extra cellular matrix (ECM), blood vessels, and nerves, remodel and grow, keeping repair possible. In advanced decay, hypoxia, and vessel regression, in complement with an immune switch, fuel nerve degeneration and

PERIODONTAL DISEASES AND SYSTEMIC VASCULITIS: A VIEW THROUGH THE PRISM OF INTERDISCIPLINARY STUDIES

Научно-практическая ревматология, 2018
The review deals with investigations aimed to examine the relationship between periodontal diseases (PDs) and a chronic autoimmune inflammatory response, the most striking models of which include systemic vasculitis (SV). PDs are associated with systemic

Identification of a Force‐Induced Sox9+Acan+ Transitional Subpopulation Linked to FGF2–FGFR2–ERK Signaling in Orthodontic Bone Remodeling

Advanced Science, EarlyView.
Mechanical loading induces a previously unrecognized Sox9+Acan+ transitional mesenchymal cell population in the periodontal ligament that promotes osteoclastogenesis via the FGF2–FGFR2–ERK axis. Targeting this mechanoresponsive stromal population using a localized GelMA@siRNA delivery strategy attenuates pathological osteoclast overactivation and root ...

Modeling chronic periodontitis in rats: Persistent alveolar bone loss mediated by periodontal pathogens

Animal Models and Experimental Medicine, EarlyView.
Irrigation of periodontal pockets with human periopathogens, in combination with a 14‐day ligature‐induced periodontitis protocol, significantly enhances alveolar bone loss and sustains bacterial colonization for up to 28 days following ligature removal, thereby more closely replicating the chronic nature of human periodontitis compared to the ligature

EFFECTS OF NON-PSYCHOTROPIC PHYTOCANNABINOIDS ON ORAL BACTERIA - IN VITRO STUDY

Česká Stomatologie a Praktické Zubní Lékařství, 2023
Introduction, aim: Maintaining homeostasis of the oral cavity is associated not only with the immune response and soft tissue metabolism but also the action of commensal and pathogenic bacteria.

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

The Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Orthodontic management of uneven gingival margins in patients with healthy or reduced periodontium to improve smile aesthetics [PDF]

Periodontology 2000, EarlyView.
Abstract Uneven gingival margins may cause visible asymmetries during smiling and may reflect alterations in the tooth shape and morphology, particularly in cases requiring restorative procedures. Despite being perceived as a minor health condition, presence of uneven gingival margins usually impacts the smile aesthetics and could affect the individual'

Strategies for Managing the Risk of Mucogingival Changes During Impacted Maxillary Canine Treatment

Turkish Journal of Orthodontics, 2020
Gingival recession is a frequent mucogingival defect in the adult population. It affects the esthetics and is related to hypersensitivity and a high risk of periodontal attachment loss.

Single-Cell Transcriptomic Analysis Reveals Developmental Relationships and Specific Markers of Mouse Periodontium Cellular Subsets

Frontiers in Dental Medicine, 2021
The periodontium is essential for supporting the functionality of the tooth, composed of diversity of mineralized and non-mineralized tissues such as the cementum, the periodontal ligament (PDL) and the alveolar bone.

3D bioprinting in oral and craniomaxillofacial tissue regeneration: Progress, challenges, and future directions

BMEMat, EarlyView.
This paper summarized the application of 3D bioprinting in the regeneration of various tissues in the oral and craniomaxillofacial fields, including the required biomaterials and printing techniques. Abstract Oral and craniomaxillofacial tissues are essential for maintaining oral functions, including respiration, mastication, swallowing, and speech ...
