The research
Clinical Studies
Published, peer-reviewed research behind the Er:YAG and Nd:YAG wavelengths used in LightWalker procedures — with the one fact from each worth remembering.
Combined Nd:YAG/Er:YAG laser therapy for periodontal disease
A randomized controlled trial found significantly better improvements in probing depth and clinical attachment level at 2 months when combined Nd:YAG/Er:YAG laser therapy was added to conventional non-surgical treatment, versus conventional treatment alone.
Er:YAG laser for caries removal and cavity prep
Early clinical trials found Er:YAG laser cavity preparation caused minimal patient discomfort, with the large majority of treated teeth requiring no local anesthesia at all.
Er:YAG laser vs. dental drill in children
A randomized trial in children comparing Er:YAG laser to a traditional drill found reduced anesthesia use, less pain, and lower anxiety with the laser, and no meaningful difference in treatment success after a year of follow-up.
Er:YAG laser antibacterial effects on oral biofilms
Lab testing of Er:YAG laser irradiation (on a LightWalker system) against oral biofilms found substantial reduction in microbial viability, with especially strong effects against Candida albicans.
LightWalker laser therapy for oral mucositis
A registered randomized trial is evaluating whether Nd:YAG LightWalker laser therapy can reduce the incidence, severity, and duration of oral mucositis in patients undergoing stem cell transplantation.
Laser-assisted caries removal — meta-analysis
A review across eleven studies found Er:YAG lasers effective for conservative caries removal, generally causing less pain and anxiety than rotary instruments, though typically taking longer to complete.
Er:YAG decontamination of failed implant surfaces
Testing on implants removed from peri-implantitis cases found that Er:YAG laser irradiation could clean carbon contamination from the implant surface, helping identify an effective decontamination protocol.
Combined Nd:YAG/Er:YAG surgical peri-implantitis treatment
A controlled trial compared combined Er:YAG/Nd:YAG laser treatment against conventional surgical debridement for peri-implantitis, evaluating clinical outcomes and bone-loss biomarkers at six months.
NightLase Er:YAG snoring treatment vs. sham
A randomized, sham-controlled trial of 40 patients found NightLase's non-invasive Er:YAG treatment significantly improved both patient- and bed-partner-reported snoring scores after three sessions, with no anesthesia needed and no complications.
Er:YAG SWEEPS/PIPS for root canal disinfection
A systematic review of 15 studies (2015–2025) found Er:YAG-activated irrigation — including Fotona's SWEEPS mode — outperformed conventional irrigation for smear layer removal and biofilm disruption, with SWEEPS showing the strongest bacterial reduction, especially near the root apex.
