- Primary Outcome Measures
Name Time Method Change From Baseline in Evaporative Air Sensitivity Pain Response on a Schiff Sensitivity Scale at Day 14 Baseline to Day 14 Response to a constant jet of air applied to hypersensitive teeth is evaluated using a Schiff Sensitivity pain response scale. According to this analog scale, pain response for each individual stimulated tooth ranged from 0 to 3; 0 - participant does not respond to air stimulation, 1 - participant responds to air stimulus but does not request discontinuation of stimulus, 2 - participant responds to air stimulus and request discontinuation of stimulus, 3 - participant responds to air stimulus, considers stimulus to be painful and request discontinuation of stimulus. Those teeth that met the tactile threshold inclusion criterion (tactile threshold ≤ 20g) were assessed at baseline and Day 14. The Investigator directed a second application of air from a standard dental syringe to the facial surface of the two sensitive teeth selected at baseline. The Schiff Sensitivity Score was calculated as the subject level mean change (on two teeth) from baseline.

Name Time Method Change From Baseline in Evaporative Air Sensitivity Pain Response on a Schiff Sensitivity Scale Immediately Post-treatment Baseline to immediately post treatment administration Response to a constant jet of air applied to hypersensitive teeth is evaluated using a Schiff Sensitivity pain response scale. According to this analog scale, pain response for each individual stimulated tooth ranged from 0 to 3; 0 - participant does not respond to air stimulation, 1 - participant responds to air stimulus but does not request discontinuation of stimulus, 2 - participant responds to air stimulus and request discontinuation of stimulus, 3 - participant responds to air stimulus, considers stimulus to be painful and request discontinuation of stimulus. Those teeth that met the tactile threshold inclusion criterion (tactile threshold ≤ 20g) were assessed at baseline and immediately after treatment. The Investigator directed a second application of air from a standard dental syringe to the facial surface of the two sensitive teeth selected at baseline. The Schiff Sensitivity Score was calculated as the subject level mean change (on two teeth) from baseline.
Change From Baseline in Evaporative Air Sensitivity Pain Response on a Schiff Sensitivity Scale at Day 3 Baseline to Day 3 Response to a constant jet of air applied to hypersensitive teeth is evaluated using a Schiff Sensitivity pain response scale. According to this analog scale, pain response for each individual stimulated tooth ranged from 0 to 3; 0 - participant does not respond to air stimulation, 1 - participant responds to air stimulus but does not request discontinuation of stimulus, 2 - participant responds to air stimulus and request discontinuation of stimulus, 3 - participant responds to air stimulus, considers stimulus to be painful and request discontinuation of stimulus. Those teeth that met the tactile threshold inclusion criterion (tactile threshold ≤ 20g) were assessed at baseline and Day 3. The Investigator directed a second application of air from a standard dental syringe to the facial surface of the two sensitive teeth selected at baseline. The Schiff Sensitivity Score was calculated as the subject level mean change (on two teeth) from baseline.
Change From Baseline in Tactile Pain Threshold Score at Day 14 Baseline to Day 14 The Response to increasing force on hypersensitive teeth was evaluated using a Yeaple Probe pain response scale (10g to 80g). According to this tactile sensitivity assessment, an increasing force is applied to hypersensitive tooth until a yes response to pain is recorded or the maximum force has been reached. Tactile testing begins with a force of 10g and it is increased by 10g, with each successive challenge, until either a "yes" response is recorded or the maximum force (80g) is reached. An increase in tactile score from baseline represents an improvement in sensitivity
Change From Baseline in Tactile Pain Threshold Score at Day 3 Baseline to Day 3 The Response to increasing force on hypersensitive teeth was evaluated using a Yeaple Probe pain response scale (10g to 80g). According to this tactile sensitivity assessment, an increasing force is applied to hypersensitive tooth until a yes response to pain is recorded or the maximum force has been reached. Tactile testing begins with a force of 10g and it is increased by 10g, with each successive challenge, until either a "yes" response is recorded or the maximum force (80g) is reached.
