The efectivity against the bacterias was determinated using diffusion method in agar o disc-plaque. Comparing oil of the pinhead and the camphorated parachlorophenol, during experimental time at the 24 hours and 72 hours. Its observated essential oil presented bigger inhibition halo at the 24 hours but without statical. significance however at the 72 hours present statical significance in favor of essential oil of the pinhead it also show us that the essential of the pinhead and camphorated parachlorophenol presented amoderate sensibility in front of the bacterias facultative anerobias (Enterococcus Faecalis) and strict anaerobia (Fusobacterium SP.)
The essential oil of the pinhead present bigger antibacterial efectivity and significative increase of the halos of inhibition at the 72 hours than 24 hours in two bacterias evaluated in comparation a camphorated parachlorophenol.
