Abstract | PURPOSE: To compare relief from dentin hypersensitivity (DH) after use of dentifrices formulated with potassium nitrate or fluoride. For the study, DH evaluations were conducted with the Jay Sensitivity Sensor Probe (Jay Probe), a novel tactile hypersensitivity instrument, in conjunction with three other DH methods, i.e. Yeaple probe (tactile), air blast, and the Visual Analog Scale (VAS). METHODS: RESULTS: 85 subjects completed the entire study with evaluable results. Both treatments resulted in significant reductions in DH from baseline to all recall visits. In comparison to the Negative control, subjects in the Test group demonstrated significantly greater reductions for all DH evaluations at both 4 and 8 weeks (P < 0.05). Average tactile DH scores at week 8 for the Test and Negative control groups were 36.25 and 15.24 with the Yeaple probe and 35 and 12.43 with the Jay probe. Correspondingly, subjects in the Test group demonstrated significantly greater reductions in air blast and VAS responses for DH than those in the Negative control group (P < 0.05).
