我科自1979年以来,用硝酸钾饱和溶液冶疗牙本质过敏70例,效果满意,报道如下。一、治疗方法用化学试剂结晶体硝酸钾(市场有售),按饱和量加入蒸馏水,水浴法加热使结晶溶解成饱和液。将患牙擦干,用小棉球蘸硝酸钾饱和液涂擦过敏部位,反复摩擦1分钟即可。偶尔咽下,无毒性,无副作用。二、效果观察本组70例,咬(牙合)面牙本质过敏34例,颈部过敏36例。全部病例治疗均得到显著的缓解,一般在涂药后酸痛即消失或明显减轻,进食时不再酸痛或明显改善。涂药1次脱敏作用最短维持1周,最长可达1年半,多数能维持1～3个月。
Since 1979, our department, with saturated potassium nitrate solution of dentin hypersensitivity in 70 cases, the results are satisfactory, are reported below. First, the treatment of chemical reagents using potassium nitrate (commercially available), according to the amount of saturated added to distilled water, water bath heating to dissolve the crystals into a saturated solution. The affected teeth dry, with a small cotton ball dipped in saturated potassium nitrate rubbed the allergy site, repeated friction for 1 minute. Occasional swallow, non-toxic, no side effects. Second, the effect of observation The group of 70 cases, bite (occlusal) facial dentin hypersensitivity in 34 cases, neck allergy in 36 cases. All cases were treated with significant relief, usually after the application of pain disappeared or significantly reduced, no longer sore when eating or significantly improved. Application of a desensitization effect for a minimum of 1 week, up to 1 year and a half, most can be maintained for 1 to 3 months.
