This was a single-centre, randomized-controlled, examiner-blind, two treatment group (test and no treatment), parallel design, stratified (by maximum baseline Schiff sensitivity score of the two selected test teeth) study, in healthy participants with at least two sensitive teeth that meet all the criteria at the screening and the baseline pre-treatment visit. Participants were screened for study suitability at screening visit (Visit 1). At Visit 2 (baseline; pre-treatment) 2 non-adjacent accessible teeth (incisors, canines, premolars) in different quadrants of the mouth and separated by at least 2 teeth (or equivalent edentulous space) were identified that demonstrated signs of sensitivity as measured by a qualifying tactile stimulus (Yeaple ≤ 20 gram [g]) and evaporative air assessment (Schiff sensitivity score ≥ 2) on the facial/cervical (ie, labial/buccal) tooth surface. Once the 2 test teeth were selected, the subjects were stratified (by maximum baseline Schiff sensitivity score of the 2 selected test teeth) and randomized to treatment or no treatment. DH was assessed at baseline (pre-treatment), and 10mins, 2 & 4 hours post-treatment.
