What this trial studies

This investigation aims to evaluate the healing of suprabony defects in patients with periodontitis by comparing two treatment approaches: one involving the application of hyaluronic acid during surgical flap elevation and the other using surgical flap elevation alone. A total of 80 patients will be randomly assigned to either the hyaluronic acid group or the no-hyaluronic acid group. The primary outcome measured will be the Clinical Attachment Level (CAL) gain, while secondary outcomes will include Probing Depth (PD) and Gingival Recession (GR). The study will utilize specific incision techniques based on the width of the interproximal space to access the defect area effectively.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older diagnosed with periodontitis and having specific suprabony periodontal defects.

Not a fit: Patients with systemic diseases, those on prolonged antibiotic or anti-inflammatory treatments, or pregnant or lactating individuals may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could enhance healing outcomes for patients with periodontal bone loss.

How similar studies have performed: Other studies have shown promising results with the use of hyaluronic acid in periodontal treatments, indicating potential for success in this approach.
