- Identify microorganism components in the serum of patients with severe periodontitis [ Time Frame: 1hour ]microorganism components will be analyzed in serum samples collected before teeth cleaning and again 5 minutes after teeth cleaning
- Characterize the immune regulator activity of periodontitis serum [ Time Frame: 1 hour ]microorganism components will be analyzed in serum samples collected before teeth cleaning and again 5 minutes after teeth cleaning
Biospecimen Retention: Samples With DNA
