牙周病是一种极为普遍的疾病,已成为成年人失牙的主要原因。它的病因是十分错综复杂的,迄今仍未能完全明了,治疗效果也常不能令人满意,特别是象青少年牙周炎(牙周变性)这样破坏广泛,进展迅速的牙周病,一直被认为是难治之症。从近几年国际动向来看,关于牙周病病因研究,由于在方法上采用了无菌隔离装置技术,连续无氧技术,免疫荧光技术,组织培养和电镜观察等手段,致使牙周病细菌病因及其机制的研究方面,取得了较大的进展,本文择要介绍了这方面的情况。 Periodontal disease is a very common disease that has become the leading cause of tooth loss in adults. Its etiology is very complex and has so far not been fully understood and its efficacy is often unsatisfactory. Periodontal diseases, such as juvenile periodontitis (periodontal degeneration), which are both widespread and rapidly progressing, have long been considered Is refractory disease. In recent years, international trends, the study on the etiology of periodontal disease, due to the methods used in aseptic isolation device technology, continuous anaerobic technology, immunofluorescence, tissue culture and electron microscopy and other means, resulting in periodontal disease bacteria Etiology and its mechanism of research, made great progress, this paper choose to introduce the situation in this area.
