Interventional human ocular safety experiments for 222‐nm far‐ultraviolet‐C lamp irradiation

Photochemistry and Photobiology, Volume 101, Issue 2, Page 517-526, March/April 2025.
To directly assess the ocular safety of 222‐nm far‐ultraviolet‐C (UVC) irradiation in humans, five subjects were exposed to 222‐nm UVC at doses of 22, 50, and 75 mJ/cm2. The findings indicate that far‐UVC irradiation does not cause “clinically significant photokeratitis” or long‐term ocular damage, though it may induce temporary discomfort.

Depth of DNA photodamage in human corneas exposed to 222 nm or 254 nm UV

Photochemistry and Photobiology, EarlyView.
Representative confocal 3D image of a section of a human cornea showing nuclei in blue (Hoechst 33342) and green, which was assigned to cells exhibiting Alexa555 conjugated to anti‐CPD antibody. The depth of photodamage was measured in Z‐stacks of the human corneal epithelium after exposure of the anterior surface to 50 or 100 mJ/cm2 at 222 or 254 nm ...

Cis‐urocanic acid formation following far‐UVC exposure and associated signaling responses in keratinocytes

Photochemistry and Photobiology, EarlyView.
Far‐UVC (200–235 nm) has emerged as a safe and effective indoor disinfection tool, but effects on skin immunomodulation remain unclear. This study demonstrates that 222 nm far‐UVC converts trans‐urocanic acid (UCA) to its biologically active cis isomer at levels comparable with solar radiation. In keratinocytes, far‐UVC alone caused modest increases in

Reviewing the benefits and clinical outcomes of oral fibroblasts over mesenchymal stem cells for repairing periodontal defects during or after orthodontic tooth movement

Periodontology 2000, EarlyView.
Abstract Orthodontic therapy applies forces to teeth, causing an inflammatory reaction in the periodontal ligament. This is repaired by remodeling of the periodontium, allowing tooth displacement. Although orthodontic therapy is mostly initiated during childhood and adolescence, the number of adults seeking this treatment is increasing as our society's
