摘要
目的:检测氢氧化钙封药前后尖周病患牙根管内细菌内毒素的变化。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。结果:根管内封氢氧化钙2周后,内毒素含量明显降低(P<0.01)。结论:氢氧化钙可以明显降低感染根管中的内毒素含量。
AIM ：To study the content alteration of bacterial endotoxin in the exudant from the root canals of periapical diseases treated with calcium hydroxide as intracanal medicament. 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. RESULTS. Contents of bacterial endotoxin in the root canals sealed with calcium hydroxide decreased significantly after 2 weeks（P 〈0.01 ）. CONCLUSION： Contents of bacterial endotoxin in the infectious root canals can be cut down obviously with calcium hydroxide treatment.
