2. Do different strains of E. faecalis have the same behavior towards intracanal medications in in vitro research?
Abstract: The aim of this study was to evaluate the antimicrobial action of different endodontic pastes against Enterococcus faecalis ATCC 29212, isolated from the urinary tract, and compare the action with E. faecalis ATCC 4083, isolated from the root canal. For this purpose, dentin blocks were infected for 21 days with both bacteria at different time-inter

4. Effect of irrigation technique for removal of triple antibiotic paste on bond strength of MTA to root dentin
Abstract This study evaluated the bond strength of mineral trioxide aggregate (MTA) to root canal dentin after the performance of various irrigation procedures to remove triple antibiotic paste (TAP). A total of 56 single-rooted human mandibular premolars were instrumented using a rotary system to size 40 and divided randomly into a control group (no intraca

5. Analysis of the reaction of subcutaneous tissues in rats and the antimicrobial activity of calcium hydroxide paste used in association with different substances
The aim of this study was to evaluate the subcutaneous tissue response in rats and the antimicrobial activity of intracanal calcium hydroxide dressings mixed with different substances against E. faecalis. Fifty four rats were divided into three experimental groups according to the vehicle in the calcium hydroxide treatment: 0.4% chlorohexidine in propylene g

6. A titration model for evaluating calcium hydroxide removal techniques
Objective Calcium hydroxide (Ca(OH)2) has been used in endodontics as an intracanal medicament due to its antimicrobial effects and its ability to inactivate bacterial endotoxin. The inability to totally remove this intracanal medicament from the root canal system, however, may interfere with the setting of eugenol-based sealers or inhibit bonding of resin

7. In vitro effectiveness of Brazilian brown propolis against Enterococcus faecalis
The aim of this study was to evaluate the in vitro antimicrobial activity of Brazilian brown propolis as an intracanal medication against Enterococcus faecalis. Thirty dentin discs prepared from intact freshly extracted bovine maxillary central incisors were infected with E. faecalis for 21 days. The specimens were distributed into six groups according to th

8. Effect of calcium hydroxide dressing on push-out bond strength of endodontic sealers to root canal dentin
The aim of the present study was to evaluate the effect of calcium hydroxide dressing on the bond strength of three commercially available endodontic sealers (MTA Fillapex, Sealapex, and AH Plus) to root canal dentin. Sixty slices of extracted human canines were obtained from cervical, middle, and apical root thirds. Root canals were standardized and specime

9. Chemical treatment of the intra-canal dentin surface: a new approach to modify dentin hydrophobicity
Objective This study evaluated the hydrophobicity of dentin surfaces that were modified through chemical silanization with octadecyltrichlorosilane (OTS). Material and Methods An in vitro experimental study was performed using 40 human permanent incisors that were divided into the following two groups: non-silanized and silanized. The specimens were pretre

10. Influência de materiais obturadores e agentes de limpeza na resistência da união e interface adesiva de pinos de fibra de vidro à dentina intrarradicular / Influence of filling materials and cleaning agents on bond strength and adhesion interface of glass fiber post to radicular dentin
The aim of this in vitro study was to evaluate the post-cement-dentin adhesive interface quality and the effect of different filling materials and cleaning agents on the bond strength of glass fiber posts to primary root dentin. This study included 156 roots of bovine primary teeth which were endodontically treated and assigned to four groups (39 teeth each

12. Influence of prior 810-nm-diode intracanal laser irradiation on hydrophilic resin-based sealer obturation
Dentin wall structural changes caused by 810-nm-diode laser irradiation can influence the sealing ability of endodontic sealers. The objective of this study was to evaluate the apical leakage of AH Plus and RealSeal resin-based sealers with and without prior diode laser irradiation. Fifty-two single-rooted mandibular premolars were prepared and divided into
