Effect of Nano-Hyaluronic Acid in Intrabony Defects Treated With Minimally Invasive Non-Surgical Technique
Sponsor: Cairo University
Summary
This randomized controlled clinical trial aims to evaluate the effectiveness of using nano-hyaluronic acid (nano-HyA) gel alongside a minimally invasive non-surgical technique (MINST) to treat deep intrabony defects in patients with Stage II and III periodontitis. While MINST is a proven method for cleaning deep periodontal pockets without the need for traditional surgery , the addition of nano-HyA may further enhance soft tissue healing, reduce inflammation, and promote regeneration. Participants in the study will be randomly assigned to one of two groups. The test group will receive the MINST procedure combined with the application of nano-HyA gel into the periodontal pocket, while the control group will receive the MINST procedure alone. The primary goal of the study is to measure the decrease in probing pocket depth over a 6-month follow-up period to determine if the adjunctive use of nano-HyA provides superior clinical and radiographic outcomes compared to non-surgical treatment alone

Minimally invasive non-surgical technique (MINST)
Subgingival debridement using thin ultrasonic tips and additional instrumentation with Gracey mini-curettes, deliberately avoiding subgingival rinsing to support blood clot stabilization
nano-hyaluronic acid
Pockets associated with intrabony defects are filled with nano-HyA paste immediately after subgingival debridement
