Randomized Controlled Trial Comparative Study
A comparison of dentifrices for clinical relief from dentin hypersensitivity using the Jay Sensitivity Sensor Probe.
To evaluate the clinical relief from dentin hypersensitivity among subjects provided with a dentifrice formulated with 8% arginine, calcium carbonate and 1,000 ppm fluoride [sodium monofluorophosphate (MFP)] in comparison to those issued a commercially available dentifrice containing 1,000 ppm fluoride [as sodium monofluorophosphate (MFP)]. Clinical evaluations for hypersensitivity were performed with a novel tactile hypersensitivity measuring instrument--the Jay Sensitivity Sensor (Jay) Probe--in conjunction with evaporative triggers by air blast (Schiff scale) and Visual Analog Scores (VAS). ⋯ 86 subjects (35 males and 51 females) complied with the study protocol and completed the entire study. At each recall visit, both treatment groups demonstrated significant reductions in dentin hypersensitivity from their corresponding baselines (P < 0.05). Subjects assigned the 8% arginine, calcium carbonate and 1,000 ppm fluoride dentifrice demonstrated statistically significant reductions in responses to tactile stimuli, air blast, and VAS responses in comparison to those using the dentifrice containing 1,000 ppm fluoride after 2, 4, and 8 weeks, respectively.

Randomized Controlled Trial Comparative Study
Clinical evaluation of the Jay Sensitivity Sensor Probe: a new microprocessor-controlled instrument to evaluate dentin hypersensitivity.
To compare the Jay Sensitivity Sensor Probe (Jay Probe), a new microprocessor-based, pre-calibrated instrument, with well accepted methods used to evaluate sensitivity, i.e. tactile response to the Yeaple Probe, air blast (Schiff scale), and patient responses by Visual Analog Score (VAS). ⋯ Low inter-examiner variability with no significant differences between replicate measurements (P > 0.05) was observed with the Jay Probe. Consistent with results from previous studies, subjects assigned dentifrices formulated with potassium nitrate or 8% arginine/calcium carbonate demonstrated improvements in Yeaple, air blast and VAS responses in comparison to those assigned the fluoride dentifrice (P < 0.05). Jay Probe responses correlated significantly with all other sensitivity measures (P < 0.05). Differences between these treatments were observed at all post-treatment evaluations using these methods.

Randomized Controlled Trial Comparative Study
Clinical assessment of a new dentifrice with 8% arginine and calcium carbonate on dentin hypersensitivity in an Indian population using a new measuring device: the Jay Sensitivity Sensor Probe.
To compare a new tactile hypersensitivity testing device [Jay Sensitivity Sensor (Jay) Probe] to three currently available methods of hypersensitivity testing: tactile hypersensitivity by the Yeaple probe, air blast (Schiff's Scale), and their overall hypersensitivity in the absence of any stimuli using the visual analog scores (VAS) during a clinical trial comparing the desensitizing potential of a dentifrice containing 8% arginine, calcium carbonate, and 1,000 ppm MFP (Colgate Sensitive Pro-Relief; Test) against a commercially available fluoride dentifrice (Colgate Cibaca; Negative control). ⋯ At the end of the 8-week period, the results showed a significant improvement in dentin hypersensitivity in the Test group as compared to the Negative control group. The mean tactile hypersensitivity scores at the 8-week examinations were 39.67 and 38.33 by the Yeaple and Jay Probes, respectively, for the Test group and 15.72 and 15.00 for the Negative control group. These observations were consistent with the other hypersensitivity examinations by air blast and VAS.

Randomized Controlled Trial Comparative Study
Measurement of dentin hypersensitivity with the Jay Sensitivity Sensor Probe and the Yeaple probe to compare relief from dentin hypersensitivity by dentifrices.
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). ⋯ 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).
