A Dual Cell‐Line Molecular Platform to Assess Sub‐Threshold Biocompatibility: Application to Processed Orthodontic Clears Aligners

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective Traditional biocompatibility assessments primarily address cytotoxicity and bulk material properties but often overlook molecular responses that occur below toxicity thresholds. Detecting these subtle effects is crucial for materials intended for prolonged contact with human tissues.

The oral microbiota and periodontal health in orthodontic patients

Periodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.

Recent Development in Solar‐to‐Hydrogen Conversion Systems

WIREs Energy and Environment, Volume 15, Issue 3, September 2026.
This review compares three solar‐driven hydrogen production methods, photocatalysis (PC), photoelectrochemical cells (PEC), and photovoltaic–electrochemical (PV–EC) systems by examining their mechanisms, materials, stability, and efficiency. Nanocrystal‐based PC catalysts achieved the highest quantum efficiency (94%), while PV–EC and Si nanowire PEC ...
