CGRP‐Loaded ROS‐Responsive Hydrogel Restores Neuro‐Angiogenic Signaling to Promote Bone Regeneration in Diabetes‐Associated Periodontitis

Advanced Science, EarlyView.
This study shows that diabetes damages sensory nerve fibers, especially CGRP‐positive ones, in the periodontium and disrupts autophagy in trigeminal ganglion neurons, affecting bone homeostasis by inhibiting type H vessel formation. To address this, CGRP@PVA/tsPBA hydrogels are developed to release CGRP in response to ROS, which binds to endothelial ...

Volumetric Engineered 3D Drug Reservoir Against Diabetic Implant Infection via Cuproptosis‐Like Bacterial Death and Hunger‐Triggered Maintenance of Mitochondrial Integrity

Advanced Science, EarlyView.
This study provides a volumetric engineered 3D drug reservoir to combat diabetic implant infection. Cu‐doped quantum dots induce cuproptosis‐like bacterial death via metabolic collapse, while glucose oxidase triggers hunger‐triggered mitochondrial protection in host cells.

Macrophage Zc3h12c Limits Tissue Inflammation and Injury via Alternative Splicing of Pre‐mRNA

Advanced Science, EarlyView.
This work defines the context‐dependent function of Zc3h12c in macrophages using the Tnfrsf11a‐Cre system. It reveals Zc3h12c's dual mechanism—regulating RNA degradation and alternative splicing—with STAT1 as a key target. The findings elucidate a novel post‐transcriptional pathway and identify STAT1 isoforms as potential therapeutic targets for kidney

An Osteoconductive Janus Hydrogel with Full Barrier Protection and Adaptable Degradation Properties for Superior Bone Regeneration

Advanced Science, EarlyView.
The filler‐barrier hydrogel system developed by dual‐network Janus structural strategy breaks through the difficulty of a single hydrogel to combine barrier protection with bone regeneration, and realizes the regeneration‐material degradation adaptation for the field of mandibular regeneration.

A Study of Skeletal Stem Cell Dynamics and Its Potential Applications in the Design of a Titanium Implant for Senile Osteoporosis

Advanced Science, EarlyView.
Senescent mesenchymal stromal cells (MSCs) drive age‐related osteoporosis (A‐OP) via adipogenic bias. Resveratrol, selected from transcriptome‐identified core genes, is delivered locally using GelMA‐chitosan hydrogel‐functionalised titanium implants. In A‐OP microenvironments, the hydrogel enables the sustained release of resveratrol, which reverses ...

Radiographic Detection of Dental Calculus [PDF]

Journal of Periodontology, 1987
To determine the sensitivity and specificity of the radiographic detection of calculus, 275 proximal tooth surfaces from 18 patients were evaluated. Standardized periapical radiographs obtained before extraction were coded, batch processed, and evaluated independently by two investigators under optimum viewing conditions.

Cytotoxic effects of dental calculus particles and freeze-dried Aggregatibacter actinomycetemcomitans and Fusobacterium nucleatum on HSC-2 oral epithelial cells and THP-1 macrophages.

The Journal of Periodontology, 2021
BACKGROUND Periodontitis is an inflammatory disease initiated by dental deposits. Microorganisms in the dental biofilm induce cell death in epithelial cells, contributing to the breakdown of epithelial barrier function. Recently, dental calculus has also
