Deep radicular grooves can predispose to pulp necrosis and the establishment of combined periodontal-endodontic lesions.

With the exception of Roth 601, which retained its antimicrobial activity, the AH-Plus, TopSeal, and AH-26 sealers all demonstrated antimicrobial properties against Enterococcus feacalis and Proteus vulgaris that diminished when set. TopSeal significantly affected Enterococcus feacalis when compared with AH-Plus. GuttaFlow and EndoREZ expressed no antimicrobial activity.
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.
