Efficacy Evaluation of Oil Pulling Oral Rinse for Gingivitis

The objective of this study was to compare the effects of an oil pulling oral rinse to a commercial oral rinse on gingivitis over a 12-week period.

A 12-week, single-center, randomized, double-blind trial was conducted, involving 66 adult volunteers with mild to moderate gingivitis. Sixty-six oral rinses were randomly assigned at baseline, with 36 participants allocated to the experimental oil pulling oral rinse (Group A) and 30 to a commercial oral rinse (CPC-based antigingivitis/antiplaque oral rinse, Group B). During the baseline visit, participants underwent an oral exam and a gingivitis assessment using the Löe-Silness Gingival Index, administered by a licensed dentist. At the second visit, after three months of product use, oral safety and gingival health evaluations were repeated. Statistical analysis included intra-group and inter-group comparisons using paired or independent t-tests as appropriate. Finally, p-values were calculated to determine the significance of observed changes.

Within-group analysis reveals that Group A exhibited a significant reduction in gingival index between the baseline and post-treatment visits, with p-values for all measurements being less than 0.001. In contrast, Group B showed no significant change in the gingival index between the visits, as the p-values for all measurements were greater than 0.05.
Additionally, inter-group comparisons of gingival index measurements between Group A and Group B suggest that Group A performed superior in reducing the gingival index compared to Group B, with p-values below 0.001, indicating a statistically significant change (improvement).

These findings suggest that the treatment administered to Group A (Gurunanda Oil Pulling Oral Rinse) had a significant impact on improving gingival indices compared to Group B (Commercial Oral Rinse) for most of the parameters measured.
These findings are not only beneficial for consumers seeking effective oral care solutions but also for healthcare professionals recommending products that deliver both safety and efficacy in maintaining oral wellness.
