The aim of this study was to evaluate antibacterial activity of the canphorated paramonochorophenol (PMCC) by direct contact and vapor against Enterococcus faecalis and Staphylococcus aureus. The test of agar difusion was the method used. It were used human extracted teeth (maxillary and mandibulary canines and maxillary and mandibulary pre-molars) that were fixed on Petri slabs by acrylic resin in order to keep the tooth crown above of the slab cover. A glass cylinder (5 mm of diameter and 1,5 cm of height) was fixed around the root apex was fixed. The direct contact test was realized by papers disks were soaked with PMCC (3 µL) that put directly in contact with the agar. For the steam test, we put a paper point into canal root soaked with PMCC (3µL) that remained per 24 hours. The results showed that the PMCC was effective against micoorganisms when in direct contact with them, with zones of bacterial inhibition. Regarding the release of vapor by PMCC into de canal root, there was no any reaction, because there was bacterial growth.
