Objective: The purpose of this study was to evaluate the antimicrobial effectiveness of intracanal medicaments on infected dentin of deciduous and permanent teeth. Methods: Dentin blocks were inoculated with Entero-coccus faecalis every 72 h for 60 days; then they were irrigated, dried and completely filled with one of the following mixtures: 1) Calcium hydroxide powder, propolis and propylene glycol; 2) calcium hydroxide powder and propylene glycol; 3) calcium hydroxide powder and sterilized water; 4) propolis and propylene glycol; 5) propolis and sterilized water. After 30 days, the samples were washed with sterilized water, immersed in Letheen Broth and incubated for 48 hours at 37 oC. Results and Conclusion: The hypothesis that the association of calcium hydroxide with propolis would be more effective than the medicaments themselves was not confirmed, as the results indicated that all the mixtures tested were not able to inhibit E. faecalis biofilm, either in dentin blocks of deciduous or permanent teeth.
