为评价脱敏剂的临床疗效，以提供一种客观定量的检测牙齿敏感症的方法，作者用自行研制的压力敏感探针和冷空气刺激方法，对７１例２１２颗牙齿敏感症患牙进行了检查比较，结果表明：①９４．８％的患牙对探诊敏感，其平均敏感阈值为２２．７９ｇ；８９．６％的患牙对冷空气刺激敏感，探诊和冷空气检测具有高度的相关性（ｐ＜０．００１）。②探诊和冷空气检测均表明，面的敏感度低于颊面，差异有显著性（ｐ＜０．０５）。③单一检测方法是不可靠的，有一定漏诊病例，在临床研究中至少要用两种以上的检查方法。④压力敏感探针是一种简便而能客观定量的检测牙齿敏感症方法。
To evaluate the clinical efficacy of desensitizer to provide an objective and quantitative method for detecting tooth sensitivity, the authors performed a series of 212 tooth-sensitive teeth using self-developed pressure-sensitive probes and cold air stimulation methods The results showed that: (1) 94.8% of the affected teeth were sensitive to exploration and the average sensitivity threshold was 22.79g; 89.6% of the affected teeth were sensitive to the cold air stimulation, and exploration and cold air detection were highly correlated (P <0.001). Both exploration and cold air tests showed that the sensitivity of the surface is lower than that of the buccal surface, the difference was significant (p <0.05). ③ single detection method is not reliable, there are some missed cases, at least two or more methods of examination in clinical studies. ④ pressure-sensitive probe is a simple and objective quantitative detection of tooth sensitivity method.
