MetS: Effects of Periodontal Therapy in Patients With Metabolic Syndrome
Study Details
Study Description
Brief Summary
A 6-month, parallel-arm, investigator-masked, randomized clinical trial was conducted in patients with MetS and severe periodontitis. Participants were randomly assigned to an Intensive Periodontal Treatment group (IPT; scaling and root planing and azithromycin capsules 500mg/24h/3days) or to a Minimal Periodontal Treatment group (MPT; professional plaque removal and placebo capsules). Blood and subgingival microbiological samples were collected at baseline, 3 and 6 months after therapy. The primary outcome was between-group difference in C-reactive protein (CRP). Secondary outcomes included HbA1c, lipids, α-1 antitrypsin, fibrinogen levels and subgingival microbiota assessment.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Sham Comparator: Minimal Periodontal Treatment (MPT) Once the hopeless teeth have been extracted, randomized patients will receive a periodontal prophylaxis, in the form of supragingival removal of all deposits (plaque and calculus) with an ultrasonic scaler in two sessions, 1 week apart. During this week the patients will be prescribed local antiseptics (chlorhexidine rinse, 2x, 10 days) and, after the last session, placebo capsules (one every 24 h for three days). |
Procedure: Supragingival Prophylaxis
Supragingival removal of all deposits (plaque and calculus) with an ultrasonic scaler in two sessions, 1 week apart.
|
| Experimental: Intensive Periodontal Treatment (IPT) Once the hopeless teeth have been extracted, randomized patients will receive non-surgical periodontal therapy in the form of full-mouth scaling and root planing (SRP), in two sessions, 1 week apart, with the use of an ultrasonic scaler (Minipiezon Electromedical Systems EMS, Nyon, Switzerland) and hand instruments, under local anaesthesia. During this week the patients will be prescribed local antiseptics (chlorhexidine rinse, 2x, 10 days) and after the last session, systemic antibiotics (azithromycin 500 mgrs, every 24 h for three days). |
Procedure: Scaling and root planning
Patients received non-surgical periodontal therapy in the form of full-mouth scaling and root planing (SRP), in two sessions, 1 week apart, with the use of an ultrasonic scaler (Minipiezon Electromedical Systems EMS, Nyon, Switzerland) and hand instruments, under local anaesthesia.

Outcome Measures
Primary Outcome Measures
- Change in C-reactive protein [Baseline, 3 months and 6 months]
Main outcome variable is the change in concentration of C-reactive protein between baseline and 6 months
Secondary Outcome Measures
- Change in Probing Pocket Depth [Baseline, 3 months and 6 months]
Examination of probing pocket depth will be determined with a periodontal probe and expressed in mm
- Change in Clinical Attachment Level [Baseline, 3 months and 6 months]
Examination of clinical attachment level will be determined with a periodontal probe and expressed in mm
- Change in Plaque Index [Baseline, 3 months and 6 months]
Examination of plaque index
- Change in Bleeding on Probing [Baseline, 3 months and 6 months]
Examination of bleeding on probing
- Change in the presence of selected periodontal pathogens [Baseline, 3 months and 6 months]
Selected periodontal pathogens: Aggregatibacter actinomycetemcomitans, Tannerella forsythia, P.gingivalis, Prevotella intermedia/nigrescens, Parvimonas micra, Campylobacter rectus and Fusobacterium nucleatum
- Change in the total counts of selected periodontal pathogens [Baseline, 3 months and 6 months]
By means of anaerobic culture. Selected periodontal pathogens: Aggregatibacter actinomycetemcomitans, Tannerella forsythia, P.gingivalis, Prevotella intermedia/nigrescens, Parvimonas micra, Campylobacter rectus and Fusobacterium nucleatum
- Change in the proportions of selected periodontal pathogens [Baseline, 3 months and 6 months]
Selected periodontal pathogens: Aggregatibacter actinomycetemcomitans, Tannerella forsythia, P.gingivalis, Prevotella intermedia/nigrescens, Parvimonas micra, Campylobacter rectus and Fusobacterium nucleatum
- Change in the concentration of Inflammatory mediators (IL-1β, IL-6, IL-8 and TNF-α) in plasma and gingival crevicular fluid [Baseline, 3 months and 6 months]
The inflammatory mediators will be determined by Luminex
- Change in the % of Glycated haemoglobin [Baseline, 3 months and 6 months]
Analysis of glycated haemoglobin was determined in the Lab of the University Hospital
