Outcome

Type Measure Description Time frame Safety issue
Primary Change From Baseline Visual Analog Scale 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. 1 Day
Secondary Change From Baseline for Air Challenge 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. A negative change from Baseline score represents a decrease in sensitivity from baseline.The mean change from Baseline was calculated for this measure. 1 Day
