Abstract
In vitro root canal dentinal tubule invasion by selected anaerobic bacteria commonly isolated from endodontic infections was evaluated. Dentinal cylinders obtained from bovine incisors were inoculated with bacteria, and microbial penetration into tubules was demonstrated by scanning electron microscopy. The results indicated that all bacterial strains tested were able to penetrate into dentinal tubules, but to different extents.
摘要
评估了从牙髓感染中常见分离出的特定厌氧菌在体外对根管牙本质小管的侵袭情况。将从牛切牙获得的牙本质圆柱体接种细菌，通过扫描电子显微镜观察微生物向小管内的渗透情况。结果表明，所有测试的细菌菌株都能够渗透到牙本质小管中，但程度不同。
