Emericid is a new polyether polycyclic ionophore antibiotic excreted by Streptomyces hygroscopicus (DS 24 367). Active in vitro against Gram-positive bacteria, it is ineffective in vivo. At a 0.006-0.02% level in the diet it protects chickens and rabbits against coccidiosis.
Introduction:Strong acid electrolysed water (SAEW), a root canal irrigant, has shown promise against resistant microorganisms like Enterococcus faecalis (E. faecalis) and Porphyromonas gingivalis (P. gingivalis).Objective: To compare in vivo antimicrobial efficacy of 3% sodium hypochlorite and SAEW against E. faecalis and P. gingivalis in primary teeth.Method: Seventy primary maxillary and mandibular posterior teeth of 4-10 year old children were irrigated either with 3% sodium hypochlorite (n=35) or SAEW (n=35). Paper point samples were collected at baseline, after chemo-mechanical preparation and 48 hours after irrigation during pulpectomy. Presence of E. faecalis and P. gingivalis in the three samples were evaluated using culture.Results: When compared to SAEW, the antimicrobial efficacy of 3% sodium hypochlorite was not significantly different (p>0.05).Conclusions: SAEW and 3% sodium hypochlorite are equally efficient irrigants against E. faecalis and P. gingivalis in necrotic primary molar teeth.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
