First seen Jan 07, 2026 · Last updated May 16, 2026 · Updated 23 times
Summary
This study looked at 88 adults to see if smoking and severe gum disease (Stage III periodontitis) cause damage to DNA and RNA. Researchers measured two markers of oxidative stress in saliva samples. They found that people with gum disease had more cell damage, and smokers with gum disease had the highest levels. The results suggest a simple saliva test could help detect gum disease and show how smoking harms cells.
