牙本质过敏症是口腔常见病之一。由于牙体组织受到磨损、酸蚀、外伤、楔状缺损、牙周萎缩等因素的影响,而致牙本质或牙颈区暴露,暴露的部位受到外界温度的、化学的、机械的刺激时,便会产生一种酸痛的感觉,而这种酸痛的感觉常随着刺激的解除而症状消失。过去曾报道过治疗的药物和方法很多,都有不同程度的效果。我们早在1962年即开始研制牙面涂料正钛酸丁酯(T.B.T)与硬脂酸铵,通过实验室和临床实践,实验病例185例656个牙,获得较好疗效。近年来我们又进一步筛选了正钛酸异丙酯(T.P.T),对硬脂酸铵作了改进,在临床脱敏治疗病例的实验中,发现上述涂料脱敏作用较强,即时疗效牙颈部有效率在90％
Dentinal hypersensitivity is one of the common oral diseases. As the tooth tissue is subject to wear and tear, acid erosion, trauma, wedge-shaped defects, periodontal atrophy and other factors, which leads to dentin or cervical area exposure, exposure to external temperature, chemical and mechanical stimuli Will produce a sore feeling, and this feeling of soreness often disappears with the release of the stimulus. In the past have reported treatment of many drugs and methods, have varying degrees of effect. As early as 1962, we started to develop toothpaste titanium tetrabutyl titanate (T.B.T) and ammonium stearate. Through laboratory and clinical practice, 185 cases of 656 teeth were tested, and we got good results. In recent years, we further screening of isopropyl titanate (TPT), ammonium stearate was improved in clinical desensitization treatment of the case of the experiment and found that the paint desensitization stronger, immediate effect of the dental neck Effective at 90%
