Dentinal Tubule Occluding Effect of Potassium Nitrate in Varied Forms, Frequencies and Duration: An In vitro SEM Analysis.

Introduction: Dentinal hypersensitivity is an exaggerated response to non-noxious sensory stimuli (osmotic, thermal or mechanical changes). An inverse relationship between occluding open tubules and the intensity of sensitivity has been reported. Studies on the efficacy of potassium nitrate used in different forms and frequencies to occlude dentinal tubules are scarce.
