牙本质过敏症,是口腔科的常见病、多发病。主要表现是当牙齿遇到酸、甜、冷、热及碰触时,产生一过性酸痛感觉。常发生在接触“酸”作业和糖果业工人,以及老年牙根暴露者和某些不正确刷牙——横刷法的人。多年来口腔医药工作者,曾进行了大量工作,探索了不少方法,但迄今为止,效果仍不理想。 Dentin allergy, is a common disease in dentistry, frequently-occurring disease. The main performance is when the teeth encounter acid, sweet, cold, heat and touch, resulting in a transient sore feeling. Often happens when people are exposed to “sour” jobs and confectionery workers, as well as elderly root-exposed people and certain incorrect brushing-cross-brushing methods. Over the years, stomatological workers have done a great deal of work and explored many methods, but so far the results have not been satisfactory.
