Outcome Measures

Primary Outcomes (1)

  • Change From Baseline 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. The higher the Schiff score, the more sensitive the tooth. The mean change from Baseline was calculated for this measure.
