Brief Summary:
Periodontitis is an inflammatory/infectious disease of high prevalence in the population and which has been linked to several chronic inflammatory systemic diseases. However, few studies have evaluated the periodontal disease in the absence of other inflammatory conditions stimulate inflammatory markers as C-reactive protein (CRP), Interleukin - 6 (IL-6) hepcidin and hemoglobin. The aim of this study was to evaluate the influence of nonsurgical periodontal therapy on the change of inflammatory markers and anemia in control subjects and patients with chronic periodontitis after three months.This interventional study included 67 individuals of both sexes, aged 30-65 years, without other diseases, except chronic periodontitis, with at least 20 teeth, selected from a total 125 individuals following the eligibility criteria. Periodontal clinical parameters (probing depth, bleeding on probing, clinical attachment level) and systemic, hematological as well as inflammatory markers CRP, IL-6 and hepcidin were compared before and after nonsurgical periodontal therapy by serum and plasma examination of control individuals and patients with chronic periodontitis.

Drug Information available for: Albendazole

Arm Intervention/treatment
Experimental: Periodontal Treatment
The experimental group underwent nonsurgical periodontal therapy, performed by a single professional who performed the scaling and root planing procedures under local anesthesia using an ultrasonic device and Gracey and mini Gracey curettes, with Robson polishing brush and prophylactic paste. This therapy was performed in two sessions at seven day intervals, with no time limit, according to the needs of each periodontal condition. In each session, subjects received oral hygiene instruction (OHI) for use of toothbrushes for the modified Bass technique, dental floss and other complementary means (interdental brush, single tuft brush, electric toothbrush, etc.) when necessary. Supportive periodontal therapy was performed in 30, 60 and 90 days. Albendazole administration.
Procedure: Periodontal Treatment
Periodontal Treatment using Gracey curettes and ultrasonic device.
Other Name: Non-surgical Periodontal Therapy

Drug: Albendazole
All participants took Albendazole 400 mg before the intervention.
Other Name: drug administration

No Intervention: No Periodontal Treatment
Individuals in the control group underwent only the polishing of tooth surfaces with Robson brush and prophylactic paste fine-grained and topical fluoride application. After 90 days, they were reassessed with the same parameters of clinical examination of the baseline.

Primary Outcome Measures :
  1. Changes in Hepcidin serum level after periodontal treatment as assessed by ELISA. [ Time Frame: 90 days ]

Secondary Outcome Measures :
  1. Changes in periodontal outcomes (Probing depth in millimeters and clinical attachment level in millimeter) after periodontal treatment. [ Time Frame: 90 days ]
  2. Percentage of sites with visible plaque and /or bleeding on probing after periodontal treatment. [ Time Frame: 90 days ]
  3. Changes in us-CRP serum level after periodontal treatment as assessed by ELISA. [ Time Frame: 90 days ]
  4. Changes in Interleukin 6 serum level after periodontal treatment as assessed by ELISA. [ Time Frame: 90 days ]

Other Outcome Measures:
  1. Changes in iron stores (Serum iron, ferritin and transferrin) after periodontal treatment. [ Time Frame: 90 days ]
