Primary Outcome Measures

Name	Time	Method
Change From Baseline Cold Water Challenge	1 Day	The Schiff Sensitivity Scale was assessed for each test tooth via a cold water challenge. The examiner recorded the Schiff Index score corresponding to the response to the cold water 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. A negative change from Baseline score represents a decrease in sensitivity from baseline. The mean change from Baseline was calculated for this measure.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline Visual Analog Scale	1 Day	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. A negative change from Baseline score represents a decrease in sensitivity from baseline. The mean change from Baseline was calculated for this measure.
