Abstract: Abstract: Objective To analyze the correlation between three assessment methods for cervical dentine hypersensitivity. Methods The assessment methods used to quantify sensitivity were the Yeaple Sensitivity Sensor Probe, Schiff scale and Visual Analogue Scale (VAS). The data of 0, 4th and 8th weeks were used to analyze the correlation of these three methods. Results The Schiff scale and VAS had well correlation consistency (r=0.26，P=0.003、r=0.49，P=4.18×10-9 and r=0.57，P=5.32×10-12) with statistical significance. Schiff scale and Yeaple scale had well correlation consistency at 8th week (r=-0.41，P=2.01×10-6), while the correlation consistency of Yeaple scale and VAS was poor. Conclusion Schiff scale and VAS can be alternative at clinical trial, and combine with the Yeaple scale.
