Histopathological evaluation of root canal filling materials for primary teeth [PDF]

, 2010
This study aimed to assess the response of apical and periapical tissues of dogs¿ teeth after root canal filling with different materials. Forty roots from dogs¿ premolars were prepared biomechanically and assigned to 4 groups filled with: Group I ...

Multiscale Coupling From Mastication to Retronasal Aroma Perception: The PG‐DTCFN Model and Multiphysics Simulation

Advanced Science, EarlyView.
Using grilled lamb skewers as a model system, this work builds a multiscale coupling framework from oral processing to retronasal aroma perception, reveals dual‐kinetic release patterns and Electroencephalogram‐characterized central encoding features, and proposes an interpretable physics‐guided deep learning model validated by multiphysics simulation,

External Inflammatory Root Resorption in Traumatized Immature Incisors: MTA Plug or Revitalization? A Case Series

Children, 2023
Introduction: External inflammatory root resorption (EIRR) in immature permanent teeth is a common complication after severe dental trauma. The management of this condition requires thorough disinfection of the root canal in order to arrest the ...

Human Dental Pulp Stem Cell Secretome Restores Ischemic Stroke–Impaired Motor and Cognitive Functions by Reprogramming Redox and Inflammatory Signaling

Advanced Science, EarlyView.
Human dental pulp stem cell secretome emerges as a cell‐free therapeutic strategy for ischemic stroke by reprogramming redox and inflammatory signaling. hDPSC secretome‐derived antioxidant and immunomodulatory factors suppress the TLR4–NOX–ROS–NF‐κB axis, reduce microglial inflammatory responses and apoptosis, and promote neurogenesis, angiogenesis ...

Effect of Oral Pathogens Associated With Pulpitis and Apical Periodontitis on Odontogenic Mesenchymal Stem Cells

Stem Cells International
Dental mesenchymal stem cells (MSCs) play an essential role in the development of immature permanent teeth. Bacterial infection of the pulp and periapical tissues of immature permanent teeth, the associated oral pathogens, and their virulence factors ...

Maturogenesis of non-vital immature permanent teeth

Contemporary Clinical Dentistry, 2013
Pulpal necrosis in young permanent teeth often results in teeth with open apex, thin root walls and poor crown root ratio. Out of the available treatment options maturogenesis has been the most conservative option that exploits full potential of pulp for

Pulp treatment for immature permanent teeth [PDF]

, 2019
For dental pulp treatment of immature permanent teeth, direct pulp capping or partial/cervical pulpotomy (apexogenesis) procedures can be used if the dental pulp is vital. MTA (Mineral Trioxide Aggregate) is regarded as the first choice dressing material

Matrix Stiffness Enhances Odontogenic Differentiation of DPSCs through Membrane Curvature Protein Baiap2‐Modulated Exosome Release

Advanced Science, EarlyView.
Matrix stiffness softening is identified as a previously underappreciated feature in deep caries. Higher stiffness drives exosome release in dental pulp stem cells through a coordinated mechanism involving PI3K–AKT‐regulated Baiap2 and kinesin‐1, thereby promoting odontogenic differentiation.

Comparison of Electric Pulp Test Threshold Values at Different Sites in Immature and Mature Permanent Teeth in 6 to 14-year-old Children: A Research Protocol [PDF]

Journal of Clinical and Diagnostic Research
Introduction: A crucial step in determining the appropriate treatment for a tooth is to assess the viability and overall status. In immature permanent teeth, where innervation is not fully developed, the electric pulp test can still be utilised by ...
