This study was conducted to evaluate the efficacy of desensitizing agent Propolis, after an in -office vital tooth bleaching and to compare its desensitizing effect to traditionally used desensitizing agent fluoride varnish. Methods: Considering the inclusion and exclusion criteria 90 patients will be selected at the OPD of Dow University of Health Sciences Ojha campus with mild to moderate discoloration and randomly divided in to three groups group A control group (fluoride varnish) group B Propolis and group C Propolis mixed with bleaching agent. After performing the bleaching procedure respective desensitizing agent was applied to each group for 10 minutes. Visual analogue scale and Schiff's scale were used to assess the sensitivity after completion of treatment. Subjective non stimulated assessment of sensitivity was done by using the visual analogue scale from day 1 till day 7 on given Performa and Objective stimulated assessment of sensitivity was done at the dental office on day 1 right after the procedure and at day 7 on follow-up after one week. Kruskal-Wallis test was applied to check median pain score and sensitivity difference between and among the groups. Mann-Whitney U test was applied to check further pairwise comparison between the groups.

Dental aesthetic is one of the great importance to the patients, various causes of tooth discoloration which usually encountered are dental fluorosis, aging, staining, smoking, medication use, etc. Different treatment options are available to treat discoloration depends on the individual case. Dental bleaching is one of the most conservative, noninvasive, low cost effective treatment modality to treat discoloration. In vital tooth bleaching dentists use 35 to 38 % hydrogen peroxide which have the deleterious effects on tooth structures. The main problem which is usually experienced by the patients with the vital tooth bleaching is dentine hypersensitivity. Methods: Considering the inclusion and exclusion criteria 90 patients will be selected at the OPD of Dow University of Health Sciences Ojha campus with mild to moderate discoloration and randomly divided in to three groups group A control group (fluoride varnish) group B Propolis and group C Propolis mixed with bleaching agent. After performing the bleaching procedure respective desensitizing agent was applied to each group for 10 minutes. Visual analogue scale and Schiff's scale were used to assess the sensitivity after completion of treatment. Subjective non stimulated assessment of sensitivity was done by using the visual analogue scale from day 1 till day 7 on given Performa and Objective stimulated assessment of sensitivity was done at the dental office on day 1 right after the procedure and at day 7 on follow-up after one week. Statistical analysis was carried out by using the software SPSS IBM version 26.Median and inter quartile range (IQR) were reported to describe continuous variables (pain and sensitivity score) Normality of continuous variable (VAS pain score and sensitivity score) was checked by using the Shapiro-wilk test and Kruskal-Wallis test was applied to check median pain score and sensitivity difference between the groups. Mann-Whitney U test was applied to check further pairwise comparison between the groups. Chi-squire test was applied and cross tabulation done to see the association between all groups and visual analog scale. P-values of less than or equal to ≤ 0.05 were used to determine the significance of all test results.
