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

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.

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.
