In this in vitro study, the antibacterial efficacy of three test materials – calcium hydroxide mixed with distilled water, mixed with camphorated mono- chlorphenol (CMCP) and an iodoform paste (Walkoff s paste) were tested against three anaerobic organisms i.e. B. melaninogenicus, B. fragilisand CI. perfringens. It was found that all the three had equal antibacterial potency and at the end of 24 hr. and 72 hrs testing, no organisms could be grown. In view of the similar bactericidal potency of the three medicaments, it was felt, that calcium hydroxide alone, mixed with distilled water should be preferred over the other two drugs. Since no additional benefits are to be derived by using either CMCP or iodoform with a liquid containing parachlorphenol, camphor, menthol, and since each of them are potential irritants, their use as an antibacterial dressing in the root canals along with calcium hydroxide, remains of questionable utility.
