Effects of Periodontal Therapy in Patients With Metabolic Syndrome

Not Applicable
Completed
Conditions
Periodontitis
Metabolic Syndrome
Interventions
Procedure: Supragingival Prophylaxis
Procedure: Scaling and root planning
Registration Number
NCT03960216
Lead Sponsor
Universidad Complutense de Madrid
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.

  • They had history of known peripheral artery disease, or chronic heart failure.
  • They had surgical treatment during the previous 3 months.
  • They had any disease that conditions compliance along the study, such as alcoholism or psychiatric disorder.

GroupInterventionDescription
Minimal Periodontal Treatment (MPT)Supragingival ProphylaxisOnce 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).
Intensive Periodontal Treatment (IPT)Scaling and root planningOnce 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).
Primary Outcome Measures
NameTimeMethod
Change in C-reactive proteinBaseline, 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
NameTimeMethod
Change in Plaque IndexBaseline, 3 months and 6 months

Examination of plaque index

Change in Bleeding on ProbingBaseline, 3 months and 6 months

Examination of bleeding on probing

Change in the % of Glycated haemoglobinBaseline, 3 months and 6 months

Analysis of glycated haemoglobin was determined in the Lab of the University Hospital

Change in Clinical Attachment LevelBaseline, 3 months and 6 months

Examination of clinical attachment level will be determined with a periodontal probe and expressed in mm

Change in the presence of selected periodontal pathogensBaseline, 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 proportions of selected periodontal pathogensBaseline, 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 fluidBaseline, 3 months and 6 months

The inflammatory mediators will be determined by Luminex

Change in the total counts of selected periodontal pathogensBaseline, 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 Probing Pocket DepthBaseline, 3 months and 6 months

Examination of probing pocket depth will be determined with a periodontal probe and expressed in mm
