不同检测方法在牙颈部牙本质敏感的临床比较研究

The clinical study of dentine hypersensitivity in buccal cervical regions

目的:本研究拟对老年人群唇颊侧牙颈部牙本质敏感的不同检测方法间的差异性及临床特征等进行了系统研究。方法:研究通过冷空气和敏感压力探针筛选出牙本质敏感症状明显的患者,比较两种检测方法的差异性、相关性,并结合敏感患病部位临床特征进一步细化分类研究。结果:冷空气和敏感压力探针方法间有统计学差异(P<0.01),检测方法间的检出率差异与病损特征存在相关性,病损区域形态分类表明,67.98%的牙颈部敏感单纯由牙龈退缩发生后根面暴露引起,29.47%的则是由牙颈部楔状缺损引起,牙本质敏感的冷空气检测和压力敏感探针检测分级评价结果没有明显相关性(P>0.05)。结论:两种牙本质敏感检测方法具有一定的互补性,检出率差异与病损形态有关系。

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.
