Conditions: Dentinal Hypersensitivity Dental Pain
Keywords: dentinal sensitivity potassium nitrate dental pain
Allocation: RANDOMIZED | Intervention model: CROSSOVER
Enrollment: 12
Healthy volunteers: no

Brief summary:
A randomized, controlled, double blind exploratory study to explore the effects of two different potassium nitrate concentrations and water on exposed dentine in reducing dentinal hypersensitivity. Solutions will be applied for either 2, 5 or 10 minutes and assessed by visual analogue scale (VAS) scores following evaporative (air) stimulus.

Detailed description:

Arms:
arm 1: Participants to receive 250 microlitres (μL) of sterile water. arm 2: Participants to receive 250 μL of potassium nitrate 5% solution. arm 3: Participants to receive 250 μL of potassium nitrate 2.5% solution.

Interventions: intervention 1: Potassium Nitrate intervention 2: Placebo
Intervention descriptions: intervention 1: 250 μL of Potassium nitrate solution (either 5% or 2.5%) intervention 2: Sterile Water
