A Novel Proline-rich Peptide Hydrogel for Periodontal Regeneration in Adult Periodontitis Patients

The goal of this clinical trial is to learn if a novel peptide-rich hydrogel works to achieve periodontal regeneration in adults. It will also learn about the safety of the hydrogel. The main questions it aims to answer are: * Does the novel peptide hydrogel achieve periodontal regeneration to a similar degree as another currently used therapy (hyaluronic acid)? * What medical problems, if any, do participants have when receiving the novel hydrogel treatment? Researchers will compare the novel peptide hydrogel to another commonly used hydrogel (hyaluronic acid) to see if the peptide hydrogel works to treat periodontal bone defects. Participants will: * Receive the novel hydorgel or hyaluronic acid when they undergo periodontal regenerative surgery * Visit the clinic at regular intervals for 1 year after the surgery for follow ups
