ABSTRACT
This article summarizes the concepts that are believed to cause dentinal hypersensitivity. It is no longer necessary and may not be feasible to obliterate dentinal tubules to obtain relief from the pain caused by dentinal hypersensitivity. In-office agents that obliterate the dentinal tubules may provide initial relief of pain, but they can impede the flow of potassium and nitrate ions toward the pulp and diminish the long-term beneficial effects seen with the routine use of potassium nitrate dentifrices. An in-office preparation that does not obliterate dentinal tubules, such as potassium nitrate gel, is recommended if potassium nitrate dentifrices are to be used for patient self-treatment. With the population living longer, dentists are challenged to maintain patients' dentition for a lifetime of comfort.

Pulpal injury commonly occurs with tooth preparation for complete fixed partial dentures. This can be documented by the substantial incidence of pain after tooth preparation. In this study, a 4% potassium nitrate-zinc oxide eugenol temporary cement was used to secure provisional crowns over recently prepared teeth and it significantly reduced the incidence and severity of pain after tooth preparation and impression taking.

Following deep restorations in vital teeth, postoperative pain of various durations frequently occurs, even if the teeth were asymptomatic before treatment. In this study, a potassium nitrate-polycarboxylate cement was used as a liner and was found clinically to tend to preserve pulpal vitality and significantly eliminate or decrease postoperative pain.
