NCT06522438

Brief Summary

This parallel-group, pilot study will test the hypothesis that the adjunctive use of a thermosensitive gel containing Hyaluronic Acid (HA) and Octenidine to non-surgical periodontal treatment (NSPT) will be able to modulate the early wound healing events. This will be assessed through the expression of specific gingival crevicular fluid markers, as well as by changes in gingival blood flow (assessed by laser speckle contrast imaging), bacterial load, soft tissues contour, clinical parameters and patient-reported outcomes. The study will involve up to 26 patients and will take place at the Centre for Oral Clinical Research (COCR), at the Institute of Dentistry, Faculty of Medicine and Dentistry, Queen Mary University of London under The Royal London Dental Hospital, Barts Health NHS Trust. Patients will be randomised to receive either NSPT alone or NSPT+ HA and Octenidine gel, and will be followed up to 3 months after treatment. The study will consist of 7- 8 visits.

Outcome Measures

Primary Outcomes (1)

  • Changes in the expression of GCF wound healing biomarkers

    Changes in the expression of GCF wound healing biomarkers at 1, 7, 15, 30 days and 3 months following treatment will be assessed. A subset of analytes involved in the healing process and signalling pathways such as i) inflammation/immune response (e.g., IL-1 β, IL-1 α, IL-6, IL-8, IL-4, IL-10,IL-17, TNF- α, MMP-1, MMP-8, MMP-9, TIMP-1), ii) bone formation/resorption (e.g., TGF- β, osteocalcin, osteopontin, osteoprotegerin, BMP-2), iii) oxidative stress (e.g., Myeloperoxidase), and iv) angiogenesis (e.g., VEGF, angiopoietin-1) will be selected based on the pathways identified and optimized in the genomic and proteomic work from our group. Multiplex immunoassays will be designed specifically for quantitative analyses in the GCF for the 2 groups at the different time points.

    Baseline, 1, 7, 15, 30 days and 3 months following treatment

Secondary Outcomes (13)

  • Changes in the Blood flow

    Baseline and at 1, 7, 15, and 30 days following treatment.

  • Changes in the bacterial load

    Baseline and at 7, 15, 30 days and 3 months following treatment.

  • Changes in the probing pocket depth (PPD)

    Baseline and at 3 months after intervention

  • Changes in the gingival recession (REC)

    Baseline and at 3 months after intervention

  • Changes in the clinical attachment level (CAL)

    Baseline and at 3 months after intervention

  • +8 more secondary outcomes

Study Arms (2)

Test Group

EXPERIMENTAL

Non-surgical periodontal treatment (NSPT) plus Hyaluronic Acid (HA) and Octenidine gel.

Combination Product: Hyaluronic Acid (HA) and Octenidine gelProcedure: Non-surgical periodontal treatment (NSPT)

Control Group

ACTIVE COMPARATOR

Non-surgical periodontal treatment (NSPT) alone.

Procedure: Non-surgical periodontal treatment (NSPT)

Interventions

Full mouth supragingival professional mechanical plaque removal (PMPR) and subgingival PMPR at sites with PPD ≥4mm will be performed with the aid of manual and power-driven instruments under local anaesthesia.

Control GroupTest Group

A thermosensitive gel with Hyaluronic Acid (HA) and Octenidine (Pocket-X®, Geistlich, Wolhusen, Switzerland) will be applied in the periodontal pockets ≥5mm immediately after the subgingival PMPR, by means of a pre-filled syringe bearing a thin plastic tip and following manufacturer's instructions.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female aged 18 and above
  • Engaged patients presenting with a Full Mouth Plaque Score (FMPS) of ≤ 20% within the 6 weeks prior to enrolment, or exhibiting a ≥ 50% reduction in plaque score from the initial screening visit.
  • Periodontitis stage III/IV (grades A to C) with at least one site per quadrant with PPD ≥5mm, bleeding on probing and attachment loss ≥5mm
  • Willing to sign informed consent and comply with study procedures

You may not qualify if:

  • Know hypersensitivity and/or allergy to any of the product's component (as per user leaflet)
  • Self-reported pregnancy or lactation
  • Smoking (current or in past 5 years), including e-cigarettes/vaping
  • Medical history including diabetes mellitus or other serious medical/ psychiatric conditions or transmittable diseases that according to the investigator may increase the risk associated with study participation
  • History of conditions requiring prophylactic antibiotic coverage prior to invasive dental procedures or/and systemic antibiotic therapy during the 3 months preceding the baseline evaluation
  • In chronic treatment with anti-inflammatory (including corticosteroids), anticoagulants/antiplatelets (including aspirin), immunosuppressants or other medication that can severely impact wound healing
  • History of alcohol or drug abuse
  • Subgingival professional mechanical plaque removal (excluding not-extensive subgingival debridement as judged by the examining clinician) and/or surgical periodontal treatment within the last 12 months
  • Other severe acute or chronic medical or psychiatric condition or psychological disorder, including limited mental capacity or language skills such that study information could not be understood, informed consent could not be obtained, or simple instructions could not be followed, or any additional conditions which, in the judgement of the investigator, would make the subject inappropriate for entry into this trial
