Oil Pulling Mouthwash Reduction in Plaque and Inflammation

Official title: Evaluation of Oil Pulling Mouthwash for Reduction of Dental Plaque, Gingivitis, and Selective Reduction of Bacteria

Run by The University of Texas Health Science Center at San Antonio · NCT07706647 · Data updated 2026-11-12

A mouthwash-based study will test whether GuruNanda oil pulling rinse can reduce plaque and gum inflammation and bleeding in healthy adults compared with a competitor mouthwash and a water placebo.

Is this trial a fit for you?

Likely a good fit

Adults 18-70 in good health with elevated gingival inflammation and plaque and at least 20 scorable teeth.

Probably not a fit

Patients with destructive periodontal disease, recent antibiotic or anti-inflammatory use, or other exclusion criteria may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, blinded study enrolls 120 adults aged 18-70 with gingival inflammation and plaque, assigning them equally to three mouthwashes for 8 weeks. Participants will use the assigned rinse once nightly while brushing habits remain the same, with baseline, 4-week, and 8-week assessments of gingival inflammation, gingival bleeding, and plaque. Examiners and staff will remain blinded to group assignments to minimize bias. Data will compare changes in gingival health and plaque across the oil pulling rinse, the competitor rinse, and the placebo water rinse.

Why it matters

Potential benefit: If successful, the oil pulling rinse could provide an effective adjunct to improve gum health and reduce plaque.

How similar studies have gone: Not specified in the description; the study builds on a known oil-pulling approach but uses a blinded, randomized design with conventional comparators.
