Photo‐Degradable Polyester Networks and Multi‐Photon Printed Objects Based on Cyclic Ketene Acetals

Advanced Functional Materials, EarlyView.
The current work introduces a photoreversible polyester network derived from radical ring‐opening polymerization of cyclic ketene acetals. It combines photoreversible cross‐linking with initiator‐free multi‐photon printing. Reversible network formation, tunable mechanical properties, and selective degradation highlight its potential as a versatile ...

A Magneto‐Mechanically Activated Nerve Guidance Conduit Promotes Peripheral Nerve Regeneration via TIMP1‐Mediated Membrane Tension Transfer

Advanced Functional Materials, EarlyView.
This study presents a magneto‐mechanical strategy that incorporates FP@MSCs into an aligned PCL/GelMA nerve guidance conduit. Magnetic stimulation increases membrane tension in FP@MSCs, triggering cytoskeletal remodeling, Schwann cell‐like differentiation, and TIMP1 secretion. TIMP1 activates ITGB1/CD63–FAK signaling in NE‐4C cells, increasing membrane

Effect of Resin Infiltration on Artificial Caries: Anin vitroEvaluation of Resin Penetration and Microhardness

International Journal of Clinical Pediatric Dentistry, 2017
To evaluate the effectiveness of resin infiltration on artificial caries lesion by assessing the depth of resin penetration and the change in microhardness of lesion postinfiltration.Totally 45 human extracted premolars were used to create an artificial demineralized lesion in enamel using demineralizing solution.

Comparative non-invasive strategies for managing dental white spot lesions: Contribution to the study of enamel remineralization

Acta Marisiensis - Seria Medica
White spot lesions (WSLs) are an early sign of enamel demineralization, requiring effective non-invasive treatments to restore esthetics and prevent progression. This study aimed to evaluate the effectiveness of fluoride varnish (GC MI Varnish) and resin
