What this trial studies

This study evaluates the efficacy of TCI188, a probiotic containing Pediococcus acidilactici, in improving oral health among individuals suffering from severe periodontal disease. Participants will be randomly assigned to receive either the probiotic or a placebo, and their oral health outcomes will be monitored over the course of the study. The focus is on patients with advanced stages of periodontal disease who have not received recent periodontal treatment. The goal is to determine if the probiotic can provide significant benefits in managing this condition.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old with severe periodontal disease who have not undergone recent periodontal treatment.

Not a fit: Patients who have received periodontal or antimicrobial treatment in the past six months, are smokers, pregnant, or have systemic diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this probiotic treatment could offer a novel, non-invasive option for improving oral health in patients with severe periodontal disease.

How similar studies have performed: While the use of probiotics in oral health is an emerging field, this specific approach with TCI188 is novel and has not been extensively tested in prior studies.
