Dentine hypersensitivity is a transient condition that often resolves with the natural sclerotic obturation of dentinal tubules. A potent topically applied in-office desensitizing treatment is indicated as the choice of treatment when dentine hypersensitivity is localized to one or two teeth.


The present study aimed to evaluate and compare the clinical efficiency of CPP-ACP F, sodium fluoride, propolis, and distilled water that was used as placebo in treating dentinal hypersensitivity.


120 patients aged 20-40 years reporting with dentinal hypersensitivity in relation to canine, premolar and molars with erosion, abrasion, and gingival recession were randomly assigned to four groups of 30 patients each. Response to air jet and tactile stimuli were measured using visual analogue scale initially on 1st, 7th, 15th, 28th, 60(th), and final assessment was done on the 90th day.


A statistical analysis was done using Anova test (Fischer's test) and Tukey HSD test for multicomparison.


The teeth treated with the test group showed decrease in the mean hypersensitivity values compared to control group, over a period of three months. The results showed propolis to be most efficient in treating dentinal hypersensitivity and CPP- ACPF showed to be the least efficient.


All test groups were effective in reducing dentinal hypersensitivity, although they differed in rapidity of action over the period of 3 months. Further studies can be done using advanced materials and techniques. Multiple therapeutic modalities have been developed to treat dentinal hypersensitivity including products that impede nerve conduction of pain stimulus, products that mechanically occlude dentinal tubules, and calcium containing products designed to create plugs in the tubules utilizing a demineralization mechanism.
