A randomized, multi-centric, double blinded three arm, Placebo, and active Controlled parallel group comparative clinical trial to assess the efficacy and safety of Gurunanda Oil Pulling Oral Rinse in reducing the sensitivity of teeth and gums.

To assess the Efficacy and safety GURUNANDA OIL pulling oral rinse in reducing the sensitivity of teeth and gums.

Objective:1.To study the efficacy of Gurunanda Oil Pulling Oral Rinse in reducing the sensitivity of teeth and gums and                                compare with Listerine Sensitivity Mouthwash and placebo.

2.To assess the safety of Gurunanda Oil Pulling Oral Rinse by monitoring the occurrence of any adverse effects.

Study Design: Three-arm, parallel-group, randomized, multi-centric, double blinded, active comparator & placebo-controlled

Primary Outcomes:

1.Objective assessment of the sensitivity of hard tooth tissue, an index of the intensity of teeth hyperesthesia (IIGZ).

2.A visual analogue scale is proposed for self-assessment by the participant of the level of pain.

3.To evaluate the cleaning effect of studied products Oral Hygiene Index Simplified (OHI-S).

4.Air Blast Hypersensitivity.

5.Examiner rates the response to stimulation of hypersensitive teeth using a jet of air  Response is rated based on the Schiff Cold Air Sensitivity Scale Response is rated based on the Schiff Cold Air Sensitivity Scale.

6.Reductions in extrinsic tooth stain area and extrinsic tooth stain intensity.

7.Photographic assessment of dental hygiene.

Secondary Outcomes:

1.Participant and Investigator Feedback will be obtained before enrollment and after completion of the study.
