Aetiology of root canal treatment failure: why well-treated teeth can fail.
LITERATURE REVIEW Root canal treatment usually fails when the treatment is carried out inadequately. However, there are some cases in which the treatment has followed the highest standards yet stillExpand

Chemomechanical reduction of the bacterial population in the root canal after instrumentation and irrigation with 1%, 2.5%, and 5.25% sodium hypochlorite.
Given the importance of bacteria in the development of periradicular lesions, the eradication of the root canal infection is paramount in endodontic treatment. This study evaluated the in vitroExpand

Antibacterial effects of endodontic irrigants on black-pigmented gram-negative anaerobes and facultative bacteria.
The antibacterial effect of endodontic irrigants was evaluated against four black-pigmented Gram-negative anaerobes and four facultative anaerobic bacteria by means of the agar diffusion test. AllExpand
