拔出的人牙的器械根管接种已知的牙髓细菌分离株。将接种的牙齿浸入适当的培养基中并在37 ℃下培养。C、不同时期链球菌在根管内大量繁殖并侵入根管牙本质小管。细菌侵入的程度是时间依赖性的。该实验模型可用于研究根管内药物对牙髓牙本质壁微生物的影响。
Instrumented root canals of extracted human teeth were inoculated with known pulpal bacterial isolates. The inoculated teeth were immersed in the appropriate culture media and incubated at 37.degree. C for varying periods. Streptococci multiplied in the root canals and invaded the radicular dentinal tubules. The extent of bacterial invasion was time-dependent. This experimental model may be useful in investigating the effect of intra-canal medicaments on microorganisms lodged in the pulpal dentin wall.
