Study summary

Study conducted in patients recruited at private praxis setting after completed step 2 periodontal therapy. Residual pockets ≥4mm with positive bleeding or such >5mm randomly allocated to either conventional subgingival re-instrumentation (controls) or to same mechanical treatment with adjectively applied hypochlorite/aminoacid gel for antiseptic reason followed by subginigival placement of cross linked hyaluronic acid gel for sealing the site after instrumentation. Re-evaluations at 3 and 9 months controlled for clinical parameters such as Periodontal Probing Depth (PPD) (CAL), Clinical Attachment Level, Gingival Recession (GR), Bleeding on Probing (BOP). The hypothesis is, sites treated with adjunctive protocol show greater PPD reduction and greater CAL gain at 9-month evaluation.

Study arms

  • Experimental
    Group A

    Test arm, patients undergo subgingival instrumentation of residual active site together with an adjunctive treatment protocol.

    Biological: subgingival instrumentation plus Perisolv / hyaDent BG

  • Placebo comparator
    Group B

    Control arm, patients undergo subgingival instrumentation of residual active site only.

    Procedure: subgingival instrumentation

Interventions

  • Biologicalsubgingival instrumentation plus Perisolv / hyaDent BG

    Group A: Perisolv is applied prior to subgingival instrumentation for disinfecting purpose, hyaDent BG seals the site for accelerated blood clot stabilisation and support of cell proliferation.

  • Proceduresubgingival instrumentation

    Group B: sites requiring re-treatment are subjected to subgingival scaling

What researchers measure

Primary outcomes

  1. Clinical Attachment Level

    Greater amount of CAL gain in the test group A vs. control group B anticipated

    Time frame: 9 month post-op

Secondary outcomes

  1. Periodontal Probing Depth

    Greater reduction in PPD for group A vs. Group B anticipated

    Time frame: 9 months post-op

  2. Gingival Recession

    Similar change in the GR depth anticipated for both groups

    Time frame: 9 months post-op

  3. Bleeding on Probing

    greater reduction in BOP anticipated for group A vs. group B patients.

    Time frame: 9 months post-op
