Laser light shows promise for treating advanced gum disease

This study tested whether adding laser therapy to standard deep cleaning improves gum health in people with severe periodontitis. Twenty adults received either antimicrobial photodynamic therapy (using a blue dye and laser) or photobiomodulation (red or infrared laser) alongside standard scaling and root planing. Researchers measured plaque, bleeding, pocket depth, and gum recession at the start and three months later.
