Clinical Study Investigating the Efficacy of a Mouthwash in Providing Long Term Relief From Dentinal Hypersensitivity
Completed · Phase 2
Conditions studied: Dentin Sensitivity
In brief
The aim of this study is to investigate the longitudinal efficacy of a potassium nitrate mouthwash formulation when used as an adjunct to brushing with a standard fluoride dentifrice for the relief of dentinal hypersensitivity (DH) compared to brushing with a standard fluoride dentifrice alone. This will be a single centre, eight week, randomised, examiner blind, two treatment arm, parallel design, stratified (by maximum baseline Schiff Sensitivity Score of the two selected test teeth) study in participants with at least two sensitive teeth that meet all the criteria at the Screening and Baseline visit. Participants will be assessed at Baseline, and at four and eight weeks to monitor clinical efficacy and safety.
