Abstract：Objective:To carry out a systematic research on the differences between different detection methods and clinical characteristics of cervical dentine sensitivity (CDH) at the labial or buccal parts of tooth in Chinese adults. Methods:The air blast and Yeaple probe were used to screen the patients with an obvious symptom of hypersensitivity. The differences and correlation between the two methods were further compared and evaluated with related the clinical features of CDH to conduct a detailed research.Results:There were significant differences between the air blast and Yeaple probe in detecting CDH(P<0.01). The differences of detection rate was correlated with lesion morphology. The morphologic classification of the sensitive area showed that approximately 70% of cervical dentine sensitivity were associated with exposed root surface caused by the single reason of gingival recession, while approximately 28% of sensitive teeth were attributed to the cervical wedge-shaped defects. There was no statistically significant relationship between the grades of both methods(P>0.05).Conclusion:Two kinds of detection method of CDH have obvious complementary effect, and the differences of detection rate of CDH were correlated with lesion morphology of cervical part of the teeth.
