[Antibacterial activity of endodontic medications].
BACKGROUND
The successful outcome of endodontic treatment depends on the elimination of bacteria present inside the root canal system. In the pulpal chronic infection, intracanal medicaments are necessary to obtain the sterilization. This study evaluated the antibacterial activities of some intracanal medicaments.


METHODS
The bacteria used were: Staphylococcus aureus, Streptococcus viridans, Escherichia coli, Bacteroides fragilis and Candida albicans; the medicaments used were: Stomidros, Stomilex, Endoidros and Cresatina. Wells were punched in plates and filled with the medicaments to be tested. The diameters of the areas of bacterial inhibition were measured and recorded after 24.48 hours and 7 days.


CONCLUSIONS
The most important result of this study is the demonstration of the inefficiency of medicaments like calcium hydroxide against Candida albicans. The Cresatina showed antibacterial activity against all bacteria used.
