TL;DR: The purpose of this paper is to discuss the aetiology of the failure of root canal treatment, particularly in cases of well-treated root canals, and indications for the treatment of endodontic failures.
Abstract: Siqueira JF, Jr. Aetiology of root canal treatment failure: why well-treated teeth can fail (Literature review). International Endodontic Journal , 34 , 1‐10, 2001. 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 still results in failure. In most of the cases, the endodontic failure results from persistent or secondary intraradicular infection. Extraradicular infections may also be implicated in the failure of some cases. In addition, it has been claimed that a few cases can fail because of intrinsic or extrinsic nonmicrobial factors. The purpose of this paper is to discuss the aetiology of the failure of root canal treatment, particularly in cases of well-treated root canals. Indications for the treatment of endodontic failures are also discussed.

TL;DR: Calcium hydroxide is not effective against all bacterial species found in root canal infections, but association with other medicaments may enhance the efficacy of the intracanal medication in eliminating residual bacteria in the root canal system.
Abstract: Literature review The primary function of calcium hydroxide as a routine intracanal medicament is to provide antimicrobial activity. However, the mechanisms of antimicrobial activity of calcium hydroxide are not well known. Physicochemical properties of this substance may limit its effectiveness in disinfecting the entire root canal system. In addition, calcium hydroxide is not effective against all bacterial species found in root canal infections. Association with other medicaments may enhance the efficacy of the intracanal medication in eliminating residual bacteria in the root canal system.

TL;DR: Diverse aspects of bacterial persistence after treatment are discussed, including the microbiology, bacterial strategies to persist, the requisites for persisting bacteria to affect the outcome, and future directions of research in this field are discussed.
756 citations
TL;DR: Investigation of the prevalence of E. faecalis in endodontic infections and whether this species is associated with particular forms of periradicular diseases indicated that it is significantly more associated with asymptomatic cases of primary endodentic infections than with symptomatic ones.
589 citations
TL;DR: The overall findings are consistent with acceptable criteria to include apical periodontitis in the set of biofilm-induced diseases.

TL;DR: Based on the actions and interactions of currently available solutions, a clinical irrigating regimen is proposed and some technical aspects of irrigating the root canal system are discussed, and recent trends are critically inspected.

TL;DR: This review attempts to identify factors that influence shaping outcomes with nickel-titanium rotary instruments, such as preoperative root-canal anatomy and instrument tip design, and implications of various working length definitions and desired apical widths.

TL;DR: Using good aseptic technique, increased apical preparation sizes, and inclusion of 2% chlorhexidine in combination with sodium hypochlorite are currently the most effective methods to combat E. faecalis within the root canal systems of teeth.
