Hyaluronic Acid and Octenidine Gel as an Adjunct to Non-surgical Periodontal Treatment

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.
