Group/Cohort Intervention/treatment
root planning Device: Mechanical periodontal therapy
Other Name: periodontal debridment

Procedure: nonsurgical periodontal therapy

Primary Outcome Measures :
  1. Evidence of alteration in periodontal pathogens by PCR [ Time Frame: One year ]
    Evaluate wich periodontal pathogens are detected before and after treatment

  2. Evidence of alteration of immunocellular response by flowcytometry [ Time Frame: one year ]
    Fenotype Monocytes, PMN, NK cells, T cells, B cells before and after periodontal treatment

  3. Evidence of alteration on pro and anti-inflammatory cytokines by CBA [ Time Frame: One year ]
    Dosage of cytokines before and after periodontal treatment
