牙髓病、尖周病中细菌的作用是无可置疑的。随着微生物学的发展,特别是厌氧培养技术的进步,人们对厌氧菌在感染根管中的生态特点愈来愈感兴趣。 本文就感染根管的厌氧菌种类,厌氧菌的药敏试验等问题进行初步探讨。 材料和方法 患者系连续两个月内就诊之牙髓坏疽或尖周炎者,共40例。 Endodontic, periapical disease in the role of bacteria is beyond doubt. With the development of microbiology, especially the progress of anaerobic culture technology, people are more and more interested in the ecological characteristics of anaerobic bacteria in infected root canal. In this paper, the type of anaerobic bacteria infected root canal, anaerobic bacteria susceptibility testing issues such as preliminary study. Materials and Methods Patients were diagnosed with pulp gangrene or periapicalis in two consecutive months, a total of 40 cases.
