Brief Summary:
The aim of this 11 study analysis was to compare the effect of bioavailable stannous fluoride (SnF2) on dentine hypersensitivity versus a positive or negative control dentifrice.

Primary Outcome Measures :
  1. Change from Baseline Air Challenge [ Time Frame: Up to 8 weeks ]
    The Schiff Sensitivity Scale is assessed for each test tooth via an evaporative air challenge. The examiner records 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.

  2. Change from Baseline in Tactile Threshold [ Time Frame: Up to 8 weeks ]
    Tactile Threshold is measured using a Yeaple probe. Testing is performed beginning at 10 g. The examiner records tactile scores for responding teeth. After treatment, testing begins at 10 g and increases by 10 g to a maximum of 50 g. The higher the tactile threshold, the less sensitive the tooth. Each successive challenge increases until a "yes" response is repeated. If a second "yes" is not obtained, the force setting is increased to the next step and continued until a force is found which elicits two consecutive "yes" responses and is recorded as the threshold on the Tactile Sensitivity Score form.
