NCT04956211

Brief Summary

A bulk of observational evidence suggests an association between periodontitis and recurrent vascular events in ischemic stroke survivors. One plausible biological mechanism relies on the systemic inflammatory response posed by periodontitis together with changes in the normal function of the vascular endothelium which might lead to recurrence in these population. A non-pharmacological anti-inflammatory treatment (non-surgical periodontal therapy) has shown to reduce systemic inflammatory markers and improve endothelial function. Therefore, we propose to carry out a 1-year follow-up pilot randomized controlled clinical trial to investigate whether control of local and systemic inflammation as well as improve function of the vascular endothelium can lead to reduce the risk of recurrence in patients diagnosed from ischemic stroke.

Outcome Measures

Primary Outcomes (1)

  • IL-6 serum levels

    Concentrations of IL-6 in serum will be measured by ELISA technique

    from baseline to 6 months after therapy

Secondary Outcomes (8)

  • Other inflammatory markers

    from baseline to 6 months after therapy

  • Flow-mediated dilatation (brachial artery)

    from baseline to 6 months after therapy

  • Intima-media thickness (carotid artery)

    from baseline to 6 months after therapy

  • Recurrent vascular events

    from baseline to 12 months after therapy

  • Lipid fractions

    from baseline to 6 months after therapy

  • +3 more secondary outcomes

Study Arms (2)

Non-surgical periodontal therapy

EXPERIMENTAL

Oral hygiene instructions will be given to all individuals. Any hopeless tooth or categorised as irrational to treat at baseline visit will be extracted at the treatment visit(s). Patients will receive a standard regimen of scaling and root planing of the root surfaces under local analgesia (depending on the severity in one or two sessions within 2 days) with curettes and ultrasonic instruments .

Procedure: Periodontal therapy

Conventional periodontal therapy

ACTIVE COMPARATOR

Oral hygiene instructions will be given to all individuals. Any hopeless tooth or categorised as irrational to treat at baseline visit will be extracted at the treatment visit(s). Supragingival cleaning and polishing of all dentition will be delivered to individuals in this group.

Procedure: Periodontal therapy

Interventions

Patients will receive a standard regimen of scaling and root planing of the root surfaces under local analgesia (depending on the severity in one or two sessions within 2 days) with curettes and ultrasonic instruments.
