- Healthy Volunteers: f

Study Arms:
- PVRP treated participants (Type: EXPERIMENTAL): Participants will receive PVRP in the chronically inflamed radical cavity at the baseline evaluation (day 0) and 1 month later (1. follow-up). There will be 2 additional follow-ups with a 1-month interval.
- Standardly treated participants (Type: ACTIVE_COMPARATOR): Participants will receive standard conservative measures for the chronically inflamed radical cavity at the baseline evaluation (day 0), 1 month later (1. follow-up), 2 months later (2. follow-up) and 3 months later (3. follow-up).

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