Laser boosts gum healing in smokers with deep pockets

This study tested whether adding a diode laser to standard deep cleaning helps smokers with severe gum disease. 33 smokers were split into two groups: one got standard cleaning alone, the other got cleaning plus laser. After 3 months, the laser group had shallower gum pockets, less inflammation, and lower oxidative stress markers. The laser appears to enhance gum healing in smokers, who often heal poorly.
