This trial tests whether a lower-strength light-activated gel (8% vs. 16%) and a shorter wait time before red light treatment (1 hour vs. 3 hours) can effectively clear actinic keratoses—rough, precancerous spots caused by sun damage—on the face. Participants will receive one of …

This trial tests whether photodynamic therapy (PDT) using methylene blue can control early-stage pericoronitis, a painful gum infection around partially erupted wisdom teeth. Thirty-four healthy young adults with early pericoronitis will receive either standard irrigation or PDT,…

This trial tests whether treating gum disease can reduce bacteria that cause lung infections in people with bronchiectasis. Participants with both conditions will receive either basic cleaning, deep cleaning, or deep cleaning plus light therapy. Researchers will measure bacteria …

This study tested whether antimicrobial photodynamic therapy (aPDT) can improve wound healing in people with diabetic foot ulcers. Researchers compared wound quality and repair in 94 participants who received either aPDT or a placebo. The goal was to see if this light-based treat…

This trial tests whether combining a gentle manual therapy called pompage with photobiomodulation (a type of light therapy using LEDs) can reduce pain and improve neck movement in people with chronic neck pain. Adults aged 18 to 55 with non-specific neck pain will be randomly ass…

This trial asks whether photobiomodulation — a type of low-level laser therapy — can lessen pain and swelling after endodontic (root-end) surgery. Thirty-four adults needing surgery on an upper tooth will be randomly assigned to receive either the laser treatment or a sham proced…

This trial tests whether photobiomodulation—a type of low-level laser therapy—can reduce pain 24 hours after orthodontic spacers are placed. Twenty-five people aged 13 to 30 who need braces will receive the laser on one side of the mouth and a sham treatment on the other. Pain le…

This trial tests whether shining red and infrared LED light on the jaw and neck muscles can reduce pain and improve movement in people with temporomandibular joint (TMJ) disorders. About 32 adults with TMJ pain will receive either real LED therapy or a placebo treatment over six …

This trial tests whether shining a low-intensity laser on the gums and face an hour before wisdom tooth extraction can lessen the swelling, pain, and jaw stiffness that follow. Thirty adults with impacted lower wisdom teeth will receive either the light treatment or a placebo pil…

This trial tests whether combining a 20% trichloroacetic acid (TCA) chemical peel with LED light therapy (photobiomodulation) can improve signs of sun damage on the hands better than the peel alone. Forty-two adults with mild-to-moderate skin aging will receive four monthly treat…

This study tested whether shining a special light (photobiomodulation) on the calf muscles can reduce spasticity in children with cerebral palsy. Twelve children aged 2 to 18 received either real or placebo light therapy once a week for two months, alongside their usual care. The…

This study looked at whether photobiomodulation (PBM) therapy, a type of light treatment, can reduce pain and improve healing for women who had perineal tears or cuts during vaginal birth. 183 women were offered PBM in addition to standard care. Researchers compared pain scores a…

This study looked at how children with a common enamel defect called MIH (molar incisor hypomineralization) use their mouths to chew and breathe compared to children without it. Researchers tested 56 children aged 6 to 12 using a standard orofacial exam. The goal was to understan…

This study looked at 26 people with peripheral arterial disease (PAD) to see how arm exercise changes oxygen levels in their leg muscles. Participants used an arm ergometer while a sensor measured calf oxygen saturation. The goal was to understand why arm training can improve leg…

This study looks at how arm cranking exercise and warm water foot immersion change blood flow and shear stress in the leg arteries of people with peripheral artery disease (PAD). Fifteen participants with PAD and claudication symptoms will complete three sessions: arm exercise, w…
