Study Arms:
- A: Diabetic + SRP + SPT (Type: EXPERIMENTAL): The first group, A, includes diabetics with periodontal disease; they will receive standard therapy, scaling \& root planing plus supportive periodontal therapy (SPT) chlorhexidine gluconate (Paroex®) mouthrinse + Soft-Picks.
- B: Non-Diabetic + SRP + SPT (Type: EXPERIMENTAL): The second group, B, includes non-diabetics with periodontal disease; they will receive standard therapy, scaling \& root planing plus supportive periodontal therapy (SPT) chlorhexidine gluconate (Paroex®) mouthrinse + Soft-Picks.
- C: Diabetic + SRP (Type: ACTIVE_COMPARATOR): The third group, C, includes diabetics with periodontal disease; they will receive standard therapy, scaling and root planing (SRP).
- D: Non-Diabetic + SRP (Type: ACTIVE_COMPARATOR): The second group, D, includes non-diabetics with periodontal disease; they will receive standard therapy, scaling and root planing (SRP).

Based on this trial design, predict the completion outcome and termination type (if applicable).
