Resumo

Objectives: To assess in vitro the antimicrobial action of intracanal medicaments in the external root surface, with or without of cementum. Methods: After the placement of intracanal medicaments, the coronal and apical openings were sealed. The antimicrobial action of 2% chlorhexidine gel (2%CHX); calcium hydroxide + 2% chlorhexidine gel (CH + 2%CHX); calcium hydroxide + 2% chlorhexidine gel + zinc oxide (CH + 2%CHX + ZnO); calcium hydroxide + saline solution (CH + SS) was evaluated against Enterococcus faecalis, Candida albicans, Actinomyces viscosus and Porphyromonas gingivalis. The samples were placed over the agar, and the zones of inhibition of microbial growth were measured after the incubation period. Results: The antimicrobial effects of the medicaments could be ranked from strongest to weakest as follows: 2%CHX, CH + 2%CHX, CH + 2%CHX + ZnO, CH + SS. No differences among groups were verified in the presence or absence of cementum. Conclusions: 2%CHX containing medicaments diffused into the dentin and reached the outer surface, exerting antimicrobial action. (C) 2008 Elsevier Ltd. All rights reserved. (AU)
