[Clinical evaluation of the paste of erythromycin ethylsuccinate-metronidazole CP for root canal sterilization].
OBJECTIVE
The infected root canal was sterilized by anti-bacteria compound paste and the efficacy was compared with FC.


METHODS
According to the mixed infection in infected root canal of anaerobic bacteria and obligate anaerobe, the paste made of erythromycin ethylsuccinate, metronidazole and CP was selected to seal and sterilize the root canal.


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.


CONCLUSIONS
The root canal sterilization drug of erythromycin ethylsuccinate metronidazole-CP was a safe and effective method to promote the restoration of root apex diseases.
