众所周知,牙周病是危害人类牙齿最严重和发病率最高的口腔疾病,是成年人特别是老年人失牙的主要原因。随着人类平均寿命的延长,牙周病将越来越被医学界所重视。造成人类丧失咀嚼功能两大疾患之一的龋病,经过人们几个世纪的探索,已经有了许多治疗方法。但是相对来说,迄今为止,在治疗牙周病的进展方面,则要缓慢得多,这不能不引起我们口腔医务工作者的焦虑。 It is well-known that periodontal disease is the most serious and morbid oral disease that endangers human teeth and is the main cause of tooth loss in adults, especially the elderly. With the extension of human life expectancy, periodontal disease will be more and more attention by the medical profession. Caries, one of the two major disorders that cause loss of human chewing, has been treated by people for centuries. However, relatively speaking, the progress made in the treatment of periodontal disease has so far been much slower, which can not but cause the anxiety of our stomatological workers.
