Oil Pulling Reduction

A total of 120 subjects who met all necessary requirements for selection as subjects will be stratified into three balanced groups (40 per group) according to age, gender, and their mean baseline gingivitis index measured using the Modified Gingival Index (MGI). The three groups will be randomly assigned to use one of three test mouthwashes: GuruNanda Oil Pulling oral rinse (test), Competitor's mouthwash (positive), Water-based oral rinse (placebo). Subjects will be instructed to use their assigned mouthwash as an adjunct oral hygiene product for the 8-week treatment duration. All subjects will be provided with the same brand of toothpaste (non-antimicrobial) and a soft-bristled toothbrush to use for their routine daily toothbrushing for the 8-week treatment duration. All study products will be used according to their manufacturers' instructions. However, to facilitate blinding, only the Randomizer will dispense the products, give instructions on the use of the products, and supervise the first use of the product at the clinical facility. The clinical Examiner and other study team members will not discuss product-use with the subjects. All mouthwash will be used once daily before bed at night, while toothbrushing will be performed twice daily in the morning and before bed at night. For each test subject, assessment data will be collected at baseline, 4 weeks, and 8 weeks. Data will be collected on gingival inflammation, gingival bleeding, and dental plaque, using Modified Gingival Index (MGI), Gingival Bleeding Index (GBI), and Rustogi Modification of the Navy Plaque Index (RMNPI), respectively. The average summary scores will be calculated for each group on each of these indices. Supragingival plaque samples will be collected for plaque microbiome analysis at baseline, 4 weeks, and 8 weeks. All dental examinations for data collection in all 120 subjects will be conducted by the same Clinical Examiner throughout the study. Subjects will be examined and queried on adverse events at each study visit.
