31The Ultimate Guide to Red Light TherapyThe researchers compared two different light colors - visible red (635 nm) and near-infrared (808 nm) - tosee how they affected human gum cells called fibroblasts.23They looked at several aspects of cell health,including cell survival, stress levels, inflammation, and changes in gene activity. The study used light settingscommonly used in dental offices.Both visible red and near-infrared light showed positive effects on the gum cells.23They increased thenumber of healthy cells, reduced signs of cellular stress and inflammation, and made the cells less likely todie prematurely. The lights also affected genes related to cell identity, suggesting they might influence howthese gum cells behave.Interestingly, the most significantimprovementsthethirdwereseentreatmentaftersession.23This finding could be importantfor dentists when planning howmanyRLTpatients.dentaltreatmentsNovaaLabRLTdevicetogiveoffersthatcanabeused at home.Overall, this study suggests that RLT could be a valuable tool in treating gum diseases, with both red andnear-infrared light showing benefits.23This information could help dentists and patients work together tomaximize the benefits of this technology. Understanding how to best use this light treatment can potentiallyimprove outcomes for patients with gum disease.Another study examined RLT for periodontitis, a specific type of gum disease that causes severe inflammationand infection of the gums, potentially damaging the soft tissue and bone that support the teeth.24The studyfocused on stem cells in the gums that are important for healing but can be blocked by inflammation.Scientists used high-intensity RLT using LED light to treat these cells and see if it could reduce inflammationand boost their healing potential.24To mimic gum disease, they inflamed the cells with a specific inflammation-causing chemical messenger called tumor necrosis factor.
