 Aims: A clinical trial which is randomized was carried out to examine the successfulness of three agents which reduces the Dentinal Hypersensitivity (DH).  Materials and Methods: A total of 90 vital teeth, was distributed separately into 3 groups in accordance with response to cold air blast and stimuli which is tactile : Group 1: treated with 10% Propolis varnish, Group 2: treated with Diode laser (970 nm), and Group 3: treated with combination of 10% propolis varnish and diode laser. Various measuring scales were used to assess patients response towards these 3 techniques. The baseline scores were obtained. The patients were evaluated at 30 min for immediate effect, 7th day for intermediate effect, 21st day for late effect and scores were recorded.  Results: Pain reduction was observed in all the 3 groups. The VAS, NRS, VDS scores were determined, and found that statistically significant reduction of Dentinal Hypersensitivity in Group 3 than Group 2 and Group 1.  Conclusion: 10% propolis varnish is used along with diode laser was seen to be statistically significant difference in decreasing the dentinal hypersensitivity as compared to other groups.
