Results The clinical observation of 180 patients with entirely developed root apex of acute and chronic apical periodontitis shown that there was no significant difference comparing erythromycin ethylsuccinate-metronidazole-CP with FC in root canal sterilization, therefore, the irritability and poisonousness of the paste can be reduced by using erythromycin ethylsuccinate-metronidazole-CP instead of FC.

为了清除髓腔病源刺激物，促进根尖病变愈合，目前国内大多用甲醛甲酚进行根管消毒。甲醛甲酚属化学制剂，虽具有强烈的杀菌作用，但亦具有刺激性、毒性和抗原性等，而琥珀酸红霉素和甲硝唑在临床上已被证明对厌氧菌有明显疗效，对于根管内的消毒杀菌作用如何，研究报道不多。
