The control of its symptomatology should, firstly, focus on preventive strategies and subsequently direct the therapy with the objective of interfering on its pain mechanism. Objective: To evaluate the short-term effectiveness of nano-hydroxyapatite based desensitizing dentifrice compared to fluoridated toothpaste on the reduction of dentin hypersensitivity. Methods: This was a double blind, randomized, parallel-group, 4-week study in 30 healthy adults with self-reported and clinically diagnosed dentin hypersensitivity, which were randomly distributed to one of the two experimental groups. Tooth sensitivity was assessed at baseline, after 2 and 4-weeks of treatment in response to evaporative and thermal stimuli measured by visual analogue scale. Results: The results obtained confirm that for both treatments there was a statistically significant reduction (p AID - 857752
