title: Antimicrobial effect of camphorated chloroxylenol (ED 84) in the treatment of infected root canals.
abstract: During and after chemomechanical preparation, particularly before the definitive filling of an infected root canal, a temporary intracanal dressing with an antimicrobial activity is generally indicated. Therefore, the aim of this study was to investigate the antimicrobial effect of ED 84, a liquid root canal disinfectant containing chloroxylenol (10%) and camphor (15%), against selected test organisms (Staphylococcus aureus, Streptococcus faecalis, Escherichia coli, and Candida albicans) both in vitro and under clinical conditions, using extracted teeth. With a contact time of 180 min between undiluted ED 84 and the four bacterial suspensions in the canal, there was a 2 to 3 log reduction in the number of organisms. Under in vitro conditions, the reduction was even greater than 3 logs. When using a liquid medication as a temporary root canal dressing for a duration of approximately 2 days, ED 84 can definitely be used.
