Objectives
Narrative objectives1
Periodontal tissue regeneration therapy is widely practiced under insurance coverage, such as REGROTH. Patients undergoing surgery must receive periodontal initial therapy to reduce inflammation at preoperative periodontal reevaluation. However, preoperative administration of antibiotics is not permitted unless there is a clear impact on systemic health. This study evaluates the efficacy of preoperative use of a highly active CPC mouthwash, using postoperative pain and the degree of improvement in clinical parameters following periodontal tissue regeneration therapy as outcomes.

Key inclusion criteria
The study population consists of 80 patients aged 20 years or older with Stage III-IV periodontitis who visited the Periodontology Department at Nihon University Matsudo Dental Hospital. Selection criteria for subjects were based on re-evaluation findings after subgingival SRP under local anesthesia and radiographic evaluation of vertical intrabony defects with bone loss depth more than 3mm and pocket depth (PD) more than 5mm. Subjects had to consent to undergoing periodontal tissue regeneration therapy (REGROTH).
Key exclusion criteria
1. Smokers 2. Patients with uncontrolled diabetes 3. Those with acute symptoms 4. Those taking medications that may affect periodontal tissues (e.g., phenytoin, nifedipine, cyclosporine A) 5.
