Objectives

Narrative objectives1

For several weeks following periodontal tissue regeneration therapy, mechanical oral hygiene management at the surgical site is not allowed. Therefore, the use of mouthwash is essential. Benzethonium chloride mouthwash, a pharmaceutical product, is widely used. However, the difference in efficacy compared to anti-inflammatory mouthwash containing tranexamic acid remains unclear. Therefore, we will evaluate the effectiveness of these products by administering postoperative management using both benzethonium chloride mouthwash and tranexamic acid-containing mouthwash during postoperative rinsing.

Key inclusion criteria

The study population consists of 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.Pregnant or breastfeeding individuals 6.Those with a history of oral cancer 7.Those with alcohol hypersensitivity.
