A Clinical Study Investigating the Efficacy of a Mouthwash in Providing Long Term Relief From Dentinal Hypersensitivity
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.

Inclusion Criteria:
- Participants in good general health, with self-reported history of dentinal
hypersensitivity lasting more than 6 months but not more than 10 years.
- Participants with minimum of 20 natural teeth.
- At screening, a minimum of four, non-adjacent teeth.
1. Teeth showing signs of facial/cervical gingival recession and/or signs of erosion
or abrasion.
2. Teeth with Gingival Index score ≤1 and a clinical mobility of ≤1.
3. Teeth that are determined to be sensitive by the participant following a 1 second
air blast to the cervical margin.
Exclusion Criteria:
- Presence of chronic debilitating disease which, in the opinion of the investigator,
could affect study outcomes.
- Any condition which, in the opinion of the investigator, causes dry mouth.
- Tooth with evidence of current or recent caries, or reported treatment of decay in 12
months of screening.
- In the 8 weeks prior to screening use of an oral care product indicated for the relief
of DH.
