The antibacterial activity of three endodontic sealers against Enterococcus faecalis in vitro [PDF]

open access: yes, 2014
Conventional root canal therapy consists of chemo-mechanical treatment of the root canal to eliminate the microbial infection. The root canal is obturated with a root filling, which normally consists of a core and an endodontic sealer. The purpose of the

Overexpression of Class III β-tubulin, Sox2, and nuclear Survivin is predictive of taxane resistance in patients with stage III ovarian epithelial cancer [PDF]

open access: yes, 2014
Failed root canal treatment is best addressed primarily with the provision of repeat endodontic treatment with thorough irrigation under isolation. If a post is present in the root of the tooth it needs to be removed first.
