Sequelae in Permanent Dentition After Traumatic Dental Injury in the Primary Dentition—A Retrospective Cohort Study

International Journal of Paediatric Dentistry, EarlyView.
ABSTRACT Background Luxation injuries to the predecessors can cause sequelae in the permanent successors. Aim To describe and analyze sequelae in permanent successors according to the child's age at the time of different luxation traumas (concussion, subluxation, extrusion, lateral luxation, intrusion and avulsion) in the primary dentition compared ...

Evaluation of Fractal and Radiomorphometric Measurements of Mandibular Bone Structure in Pediatric Patients With Molar Incisor Hypomineralization

International Journal of Paediatric Dentistry, EarlyView.
ABSTRACT Background Molar incisor hypomineralization (MIH) is associated with enamel's existing qualitative developmental defects. Aim This study aimed to assess the cortical and trabecular mandibular bone morphology in pediatric patients with MIH using fractal analysis (FA) and digital panoramic radiography (DPR) with various radiomorphometric indices.

The Importance of Connexin 43 in Enamel Development and Mineralization

Frontiers in Physiology, 2018
During enamel development, formation of hydroxyapatite crystals and regulation of pH in the enamel matrix require massive transport of ions. Both ameloblasts and adjacent dental epithelial cells in the stellate reticulum co-express several transmembrane ...

Life history data derived from the dental histological analysis of Giraffa camelopardalis: Implications for the palaeohistology of extinct giraffids

Journal of Anatomy, EarlyView.
The study of incremental lines in the dentine (left), cementum (centre) and enamel (right) of the giraffe revealed key information about the rate and pattern of dental growth in this vertebrate. These results were also useful to obtain data on the biology and life history of the species and sets the stage for future palaeohistological analysis in ...

Ameloblastic fibrosarcoma – A rarity?

JPRAS Open, 2019
Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic tumour classified by the WHO (1992) as an odontogenic sarcoma and defined as “a neoplasm with a similar structure to ameloblastic fibroma (AF) but in which the ectomesenchymal component shows the features of a sarcoma.” The first report of AFS was published by Heath in 1887.

Lungfish‐like antero‐labial tooth addition and amphibian‐like enameloid‐enamel transition in the coronoid of a Devonian stem actinopterygian

Journal of Anatomy, EarlyView.
The tooth patterning logic, which cannot be inferred from surface morphology, is revealed by visualizing buried tooth remnants in 3D. The primary teeth are added labially, initially organized in radial rows, which transition into linear rows where the coronoid becomes slender.

MDM2-Mediated p21 Proteasomal Degradation Promotes Fluoride Toxicity in Ameloblasts

Cells, 2019
Fluoride overexposure is an environmental health hazard and can cause enamel and skeletal fluorosis. Previously we demonstrated that fluoride increased acetylated-p53 and its downstream target p21 in ameloblast-derived LS8 cells. However, p21 function in

Na+ and K+ transport and maturation stage ameloblast modulation

Frontiers in Physiology, 2023
Introduction: Enamel mineralization requires calcium transport into the extracellular matrix for the synthesis of hydroxyapatite (HA) crystals. Formation of HA releases protons into the matrix, which are then neutralized when ameloblasts modulate from ...

Inflammation and mechanical force‐induced bone remodeling

Periodontology 2000, EarlyView.
Abstract Periodontitis arises from imbalanced host–microbe interactions, leading to dysbiosis and destructive inflammation. The host's innate and adaptive immune responses produce pro‐inflammatory mediators that stimulate destructive events, which cause loss of alveolar bone and connective tissue attachment.

Design Principles Of Inorganic‐Protein Hybrid Materials for Biomedicine

Exploration, Volume 5, Issue 3, June 2025.
Inorganic protein hybrid materials (IPHMs) due to editable structure present unrivalled potential at the intersection of synthetic biology and materials science. The synthesis of IPHMs with a high degree of biosafety from bioactive units represents a shift in material design and synthesis.
