B. gingivalis and F. nucleatum probably were related to acute periapical inflammation of deciduous teeth. 牙龈类杆菌、具核梭杆菌可能与乳牙根尖周炎的急性症状有关。
Bacteriodes and eusobacterium especially B. gingivalis and F. nucleatum have been more frequently isolated from root canals with acute periapical inflammation than that with chronic ones (P<0.05). 急性炎症组类杆菌、梭杆菌的检出率明显高于慢性组(P<0.
METHODS: Standard curve of endotoxin was established and the exudant from root canals of 20 cases with acute periapical diseases was used to detect the contents of bacterial endotoxin by AOL method. 方法:取20个急性尖周病患牙根管渗出液,建立内毒素标准曲线,鲎试剂检测内毒素含量。
