摘　　要：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。AbstractTwo methods were tested for measuring the sensi-tivity of dentin to mechanical (force-sensitive probe)and cold air stimuli. Of the 212 sensitive teeth in 71 pa-tients, 94. 8% were sensitive to probe, with a meanthreshold of 22. 799; 89. 6% were sensitive to cold air.These two methods were significantly correlated(P<0. 001). The occlusal sites were less sensitive thanthe buccal sites measured by probe and cold air. It sug-gests that force-sensitive probe is a simple, quantitativemethod for measuring tooth hypersensitivity.
