What this trial studies

This study evaluates the effectiveness of MAXPOWER Biological Antibacterial mouthwash in eradicating oral Helicobacter pylori (H. pylori) in patients aged 18-70 who test positive for the bacteria. Traditional antibiotic therapies have proven ineffective against oral H. pylori, necessitating the development of an antibiotic-free mouthwash. Participants will be recruited from Changhai Hospital, and their eligibility will be determined through a saliva test for H. pylori. The study aims to provide a safer and more effective alternative for treating oral H. pylori infections.

Who should consider this trial

Good fit: Ideal candidates are oral H. pylori-positive patients aged 18-70 who are visiting the outpatient clinic of Changhai Hospital.

Not a fit: Patients with significant gastrointestinal conditions or serious concomitant illnesses will not benefit from this study.

Why it matters

Potential benefit: If successful, this mouthwash could provide a non-antibiotic solution for patients suffering from oral H. pylori infections, reducing the risk of antibiotic resistance.

How similar studies have performed: While traditional methods have struggled with oral H. pylori, this approach is novel and has not been extensively tested in similar studies.
