Real-Time Assessment of Dentinal Fluid Flow Reduction by Desensitising Agents Using Subnanolitre Flow Measuring System

International Dental Journal
Objective: This study aimed to evaluate and compare the dentinal tubule-occluding efficacy of various desensitising toothpastes and a sodium fluoride varnish using a subnanolitre scaled fluid flow measuring device (NFMD). Methods: Bovine dentin specimens

Engineering programmable peptide hydrogels for chronic refractory wounds: A mechanism‐driven framework

BMEMat, EarlyView.
To break the self‐perpetuating pathology of chronic wounds, we propose a mechanism‐driven engineering framework for peptide‐based hydrogels. This review elucidates a hierarchical strategy—from molecular design to intelligent, multi‐functional systems—that enables these programmable biomaterials to dynamically intervene in key pathological loops and ...

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

Developmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

The Effect of Nano-Hydroxyapatite Particles on Dentinal Tubule Occlusion and Adjunctive Use of Ozonated Olive Oil (Scanning Electron Microscopic Study)

The Egyptian Journal of Histology
Background: Dentin hypersensitivity (DH) is a prevalent dental condition marked by sudden pain resulting from the exposure of dentinal tubules. Two main strategies are proposed for addressing this clinical dental issue: occlusion of dentinal tubules and ...

Notoginsenoside R2 Antagonizes Renal Interstitial Fibrosis by Regulating Fatty Acid Oxidation via the CASP2/ALDH3A1 Axis

Phytotherapy Research, EarlyView.
Proposed mechanism by which notoginsenoside R2 (NGR2) attenuates renal interstitial fibrosis. In injured renal tubular epithelial cells, CASP2 downregulation and enhanced ubiquitin‐dependent degradation of ALDH3A1 disrupt mitochondria‐associated endoplasmic reticulum membranes (MAMs) and impair fatty acid oxidation (FAO), leading to lipid accumulation ...

Comparison of the effect of propolis varnish and green tea varnish on treatment of dentinal hypersensitivity: An In vitro scanning electron microscope study

Biomedical and Biotechnology Research Journal, 2023
Background: Dentin hypersensitivity (DH) is perceived as pain to any stimuli, affecting all individuals. Propolis and green tea are natural, nontoxic substances.

Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

What Outcomes Matter in Vital Pulp Therapy? Current Concepts and Challenges

Australian Dental Journal, EarlyView.
ABSTRACT Vital pulp therapy (VPT) has re‐emerged as a practical and biologically sound alternative for managing deep caries and carious pulp exposures. Although its clinical use is now widespread, the outcomes used to judge the success of VPT remain inconsistent and often difficult to compare across studies.
