Treatment of Intraosseous Periodontal Defects With Hyaluronic Acid

Federico II University22 enrolled

Overview

The aim of the present investigation will be evaluate the healing of periodontal intraosseous defects following Minimally Invasive Non Surgical Debridement (MINSD) and application of a hyaluronic acid-based gel, compared to MINSD alone. A total of 22 patients will be enrolled, selected by inclusion and exclusion criteria and randomly divided in two groups: hyaluronic acid group (HA) and no-hyaluronic acid group (No-HA).

The objective of the study will be compare the healing of periodontal intraosseous defects following treatment with Minimally Invasive Non Surgical Debridement (MINSD) and application of hyaluronic acid (HA) compared to MINSD alone. Twenty-two patients with intraosseous periodontal defects will be randomly assigned to treatment with MINSD and application of a hyaluronic acid-based gel (HA Group) or MINSD alone (No-HA Group). Primary outcome will be "Probing Depth" (PD), while the secondary outcomes will be "Clinical Attachment Level" (CAL) gain, "Gingival Recession" (GR) and "Radiographic Defect Angle" (RDA). After local anesthesia, in HA group MINSD will be performed using an ultrasonic scaler with fine tips and micro-curette; then, a hyaluronic acid-based gel will be applied to the intraosseous periodontal pockets. In the No-HA group, only subgingival mechanical debridement (MINSD) will be performed with an ultrasonic scaler with fine tips and micro-curette. Finally, a polishing paste will be applied to the supra-gingival level in both groups using a rubber cup. Patients of both groups will be recalled every month for professional oral hygiene and, after 6 months, all measurements will be repeated and the final evaluation will be carried out.
