Exclusion Criteria:
1) Agressive Periodontitis subjects; 2) Systemic conditions known to affect the periodontal status; 3) medications known to affect the outcomes of periodontal therapy; 4) Hematological disorders and insufficient platelet count (<200,000/mm3); 5) pregnancy/lactation; and 6) Smoking and tobacco use in any form 7) Immunocompromised individuals.
