13. Apical adaptation, sealing ability and push-out bond strength of five root-end filling materials
This study compared the fluid filtration, adaptation to the root canal walls, and the push-out bond strength of two resin-based sealers and three calcium silicate-based retrograde filling materials. Fifty maxillary canines were shaped using manual instruments and the apical portion was sectioned. Retrograde cavities of 3-mm depth were prepared. The specimens

14. A microleakage study of gutta-percha/AH Plus and Resilon/Real self-etch systems after different irrigation protocols
The development and maintenance of the sealing of the root canal system is the key to the success of root canal treatment. The resin-based adhesive material has the potential to reduce the microleakage of the root canal because of its adhesive properties and penetration into dentinal walls. Moreover, the irrigation protocols may have an influence on the adhe

15. Comparison of different retreatment techniques and root canal sealers: a scanning electron microscopic study
The aim of this study was to evaluate the effectiveness of two retreatment techniques, in terms of the operating time and scanning electron microscopy (SEM) results, in removing three different root canal sealers from root canals that were previously filled with gutta-percha. Sixty extracted single-rooted human premolars were divided into three groups and fi

16. Comparative evaluation of push-out bond strength of a MTA-based root canal sealer
AIM: To evaluate the bond strength to root dentin of three root canal sealers: a mineral trioxide aggregate (MTA)-based sealer (MTA Fillapex(r)), an epoxy resin-based sealer (AH Plus(r)), and a zinc oxide eugenol-based sealer (EndoFill(r)). METHODS: Thirty extracted single-root human teeth of similar sizes and circular canals were prepared using #3 and

17. Influence of radiopaque fillers on physicochemical properties of a model epoxy resin-based root canal sealer
Objective: To verify the influence of radiopaque fillers on an epoxy resin-based sealer. Material and Methods: Experimental sealers were formulated by adding 20%, 40%, 60%, 80%, 100% and 120% of calcium tungstate, ytterbium trifluoride or barium sulphate by weight to an epoxy-resin-base. Setting time, flow, film thickness, radiopacity, sorption, solubi

18. Etidronate from Medicine to Endodontics: effects of different irrigation regimes on root dentin roughness
An increase in dentin roughness, associated with surface composition, contributes to bacterial adherence in recontaminations. Surface roughness is also important for micromechanical interlocking of dental materials to dentin, and understanding the characteristics of the surface is essential to obtain the adhesion of root canal sealers that have different phy

19. Human tooth germ stem cell response to calcium-silicate based endodontic cements
OBJECTIVE: The aim of this study was to compare the cytotoxic effects of endodontic cements on human tooth germ stem cells (hTGSCs). MTA Fillapex, a mineral trioxide aggregate (MTA)-based, salicylate resin containing root canal sealer, was compared with iRoot SP, a bioceramic sealer, and AH Plus Jet, an epoxy resin-based root canal sealer. MATERIAL AND M

20. Bismuth subcarbonate as filler particle for an Epoxy-based root canal sealer
Introduction: The aim of this study was to evaluate the addition of bismuth subcarbonate with different concentrations regarding the rheological properties of an experimental epoxy-based root canal sealer. Materials and Methods: Endodontic sealers were prepared with epoxy resin-based sealer with bismuth subcarbonate additions of 20%, 40%, 60%, 80%, 100%, and

22. Influence of root canal sealer on the radiographic appearance of filling voids in maxillary single-rooted teeth
OBJECTIVE: This study compared the influence of three epoxy resin-based sealers with distinct radiopacities on the observers' ability to detect root canal filling voids during radiographic analysis. MATERIAL AND METHODS: The root canals of 48 extracted maxillary canines were prepared and divided into three groups. Each group was laterally condensed with one

23. 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

24. Influência de irrigantes na resistência de união de cimentos endodônticos resinosos à dentina radicular
Avanços na tecnologia adesiva reforçam a busca por recursos para minimizar a infiltração marginal coronária e apical através do aumento da adesão entre o material obturador e as paredes do canal radicular. Neste sentido, diversos cimentos obturadores resinosos foram desenvolvidos. O uso de irrigantes pode influenciar na adesão destes materiais à den
