The hypotheses tested were that levels of C-Reactive Protein (CRP) would be higher in patients with chronic periodontitis in comparison with those without periodontal disease and that the non-surgical periodontal treatment would decrease levels of CRP in patients with chronic periodontitis.

Condition Intervention
Chronic Periodontitis Atherosclerotic Cardiovascular Disease Procedure: Non-surgical periodontal treatment

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: Short-term Changes on C-Reactive Protein (CRP) Levels After Non-surgical Periodontal Treatment

Further study details as provided by André Barbisan de Souza, State University of Maringá:

Primary Outcome Measures:
  • C-Reactive Protein levels [ Time Frame: Baseline and 60 days after treatment ]

Secondary Outcome Measures:
  • The effect of non-surgical periodontal treatment on patients with chronic periodontitis [ Time Frame: Baseline and re-evaluation 60 days after the end of treatment ]

Enrollment: 44
Study Start Date: January 2010
Study Completion Date: July 2011
Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Chronic periodontal disease
C-reactive protein levels assesments and periodontal treatment
Procedure: Non-surgical periodontal treatment
Patients included in the test group were submitted to a non-surgical periodontal treatment protocol, which consisted of oral hygiene orientation and motivation followed by mechanical plaque control involving scaling and root planning using Gracey curets (Hu-Friedy Manufacturing, Chicago, IL, USA) and ultrasonic instrumentation (Cavitron Ultrasonics, Long Island City, NY, USA), under local anesthesia (Mepivacaine 2% with epinephrine 1:100000). The treatment was performed in one or two sessions depending on the extension of the patient's periodontal condition. Patients that presented teeth unreasonable to treat due to advanced periodontitis, or any other condition were extracted under local anesthesia.
No Intervention: Periodontally healthy


Ages Eligible for Study:   35 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

Patients should have ≥ 20 teeth present; (ii) absence of oral soft tissue lesions; (iii) have ≤ 3 carious lesions in all teeth. In addition, to be included in the Test group the subject had to present chronic periodontitis (involvement of at least 5 teeth with at least one site presenting probing depth (PD) ≥ 5 mm and clinical attachment loss (CAL) ≥ 3 mm) while to be included in the Control group the patient had to exhibit periodontal healthy (bleeding on probing (BOP) < 30% of the sites and absence of any PD > 4mm associated with BOP).

Exclusion Criteria:

(i) periodontal disease treatment in the previous six months; (ii) aged less than 35 years; (iii) systemic conditions such as history of CVD or any other chronic or immunologic diseases and the use of related drugs in the previous six months; (iv) smokers or former smokers; (v) pregnant or lactating women; (vi) hypertension (>140 systolic and > 90 diastolic mmHg); (vii) obesity (Body Mass Index (BMI) ≥ 30 kg/m²); (viii) levels of HDL-cholesterol > 35.0 mg/dL (ix) levels of LDL-cholesterol < 160.0 mg/dL (x)levels of triglycerides < 400.0 mg/dL and (xi) levels of glucose levels < 100 mg/dL.
