About this trial
This is an interventional treatment trial for Dentin Sensitivity focused on measuring Sensitivity
Eligibility Criteria
Inclusion Criteria:
- be at least 18 years of age
- sign an informed consent form and be given a copy
- be in good general health as determined by the Investigator/designee

- agree to not participate in any other oral care study for the duration of this study
- agree to return for scheduled visits and follow all study procedures
- have dentinal hypersensitivity with at least one tooth with a Schiff sensitivity score of at least 1 in response to the examiner applied cold water challenge
Exclusion Criteria:
- severe periodontal disease, as characterized by purulent exudate, generalized mobility, and/or severe recession

Outcomes
Primary Outcome Measures
Change From Baseline for Visual Analog Scale - Cold Water
Visual Analog Scale (VAS) - subjects are asked to look at a VAS and designate the level of hypersensitivity they experienced as a result of the thermal and water challenges using a continuum scale of 0 = No tooth pain up to 100 = Worst tooth pain ever experienced.
Change From Baseline for Dentin Sensitivity Cold Water as Assessed by the Schiff Index
The Schiff Sensitivity Scale was assessed for each test tooth via an evaporative air challenge. The examiner recorded the Schiff Index score corresponding to the response to the air challenge. The Schiff Index Sensitivity scale is scored as follows- 0: tooth/subject did not respond to stimulus, 1: tooth/subject responds to stimulus, but does not request discontinuation of stimulus, 2: tooth/subject responds to stimulus and requests discontinuation or moves form stimulus, 3: tooth/subject responds to stimulus, considers stimulus to be painful, and requests discontinuation of the stimulus. The higher the Schiff score, the more sensitive the tooth. The mean change from Baseline was calculated for this measure.
Change From Baseline for 5 Face Emoticon Scale
Scale to score their comfort/discomfort that ranges from -2 to +2 where a -2 is considered very comfortable and a +2 is considered very uncomfortable.
