Can spit reveal how smoking fuels gum disease?

This study looks at whether smoking and advanced gum disease (Stage III periodontitis) are linked to changes in three saliva markers: TNF-α, FoxO-1, and SIRT-1, which are involved in inflammation and stress responses. Researchers will compare saliva samples from 80 adults divided into four groups: healthy non-smokers, non-smokers with gum disease, healthy smokers, and smokers with gum disease. The goal is to understand how smoking and gum disease together affect the body's inflammatory pathways, which could inform future prevention and treatment approaches.
