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.

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

Clinical Attachment Level
Greater amount of CAL gain in the test group A vs. control group B anticipated
Time frame: 9 month post-op
Periodontal Probing Depth
Greater reduction in PPD for group A vs. Group B anticipated
Time frame: 9 months post-op
Gingival Recession
Similar change in the GR depth anticipated for both groups
Time frame: 9 months post-op
Bleeding on Probing
greater reduction in BOP anticipated for group A vs. group B patients.
Time frame: 9 months post-op
