13. 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

14. Sealability of MTA and calcium hydroxidecontaining sealers
OBJECTIVES: The aim of this study was to evaluate the apical sealability of Fillapex®, endo-CPM-Sealer® and Sealapex®. Material and Methods: Ninety-four freshly extracted single-rooted teeth were selected and decoronated. All teeth were radiographed to confirm the existence of a single and straight root canal, which was prepared using Protaper Universal a

15. Avaliação in vitro da ação antimicrobiana de três cimentos endodônticos modificados com nanopartículas de prata
One of the functions of the filling of root canals is complete it as airtight as possible, stimulating the repair of periapical tissues and preventing microorganisms able to reinfect the root canal system. So it is necessary that the sealer has some desirable properties. Among these, there is the need to be bactericidal, or at least, be detrimental to bacter

16. Infiltração bacteriana em canais radiculares obturados com diferentes cimentos endodônticos e duas técnicas obturadoras / Bacterial leakage in root canals filled with different endodontic sealers and two techniques
O objetivo deste estudo foi avaliar ex vivo a infiltração do Enterococcus faecalis em canais radiculares obturados com os cimentos endodônticos AHPlus, RealSeal e o cimento experimental Sealepox, pelas técnicas da condensação lateral e compactação vertical. Cem dentes humanos unirradiculados, com canais únicos e retos, tiveram os mesmos instrumentad

17. Bond strength of different endodontic sealers to dentin: push-out test
OBJECTIVE: The aim of this in vitro study was to evaluate the bond strength of different root canal sealers to dentin. MATERIAL AND METHODS: Forty extracted single-rooted human teeth were examined and the coronal and middle thirds of the canals were prepared with a 1.50 mm post drill (FibreKor Post System, Pentron). The teeth were allocated in two experiment

18. The effect of irrigation solutions on the apical sealing ability in different root canal sealers
The aim of this study was to assess the effect of three root canal irrigation solutions on the apical sealing ability of three root canal obturation materials: gutta-percha/AH plus or MM-seal and Resilon/Epiphany SE. A total of 100 teeth with single straight root canals were randomly divided into three equal groups of 30 samples each, with the other 10 teeth

19. Effect of immediate and delayed post space preparation on the apical seal of root canals obturated with different sealers and techniques
During mechanical preparation of the post space, the root canal filling may be twisted or vibrated, depending on several factors associated with the preparation technique and quality of filling. OBJECTIVE: The purpose of this study was to investigate the effect of immediate and delayed post space preparation on the integrity of the apical seal. MATERIAL AND

20. Quality analysis of the apical seal of root canals irradiated with Nd: YAG, diode or Er: YAG lasers and filled with AH Plus, EndoREZ®, Epiphany® or Epiphany SE® resin based sealers / Análise da qualidade do selamento apical de canais radiculares irradiados com os lasers de Nd:YAG, diodo ou ER:YAG e obturados com os cimentos resinosos AH Plus, EndoREZ®, Epiphany® ou Epiphany SE®
O objetivo deste estudo foi analisar a influência da irradiação com lasers de alta intensidade antes da obturação de canais radiculares com cimentos endodônticos resinosos no selamento apical. Raízes permanentes humanas (n=168) foram endodonticamente tratadas e, então, divididas aleatoriamente em quatro grupos experimentais (n=42), de acordo com o tr

21. Influência da radiopacidade dos materiais obturadores sobre a sensibilidade, especificidade e confiabilidade da análise radiográfica de obturações endodônticas / Influence of root canal sealing materials radiopacity on sensitivity, specificity, and reliability of radiographic root canal fillings exam
The aim of this study was to investigate the effect of different radiopaque sealers in the sensitivity, specificity and realiability of radiographic root canal filling exam. After radiopacity distinction of root canal sealing materials, a total of 80 extracted single-rooted upper canines had their canals prepared with classic technique before being divided i

22. Influence of different biomechanical preparation auxiliary substances on the adhesion of AH Plus and Epiphany cements to intra-radicular dentine / Influência de diferentes substâncias auxiliares do preparo biomecânico na adesividade dos cimentos AH Plus e Epiphany à dentina intraradicular
The present study evaluated in vitro, using the push-out test, the bond strength of AH Plus and Epiphany sealers to root canal dentine treated with aqueous and gel auxiliary substances used biomechanical preparation. Roots of 100 canines were sectioned transversally at the cemento-enamel junction and at 4 mm below this section in the apical direction, provid

23. Microbial leakage and apical inflammatory response in dog's teeth after root canal filling with different sealers, post space preparation and exposure to the oral environment
Coronal leakage is an important factor affecting the outcome of endodontic therapy. This study evaluated the microbial leakage (ML) and the apical inflammatory response (AIR) in dog's teeth after root canal filling with three endodontic sealers, post preparation and exposure to the oral environment, testing the hypothesis that there is a positive correlation

24. Cimentos resinosos endodônticos: selamento apical, aspectos micromorfológicos, características físicas e resistência de união à dentina / Resin-based root canal sealers: apical sealing, micromorphological aspects, physical characteristics and bond strength to dentin
Resin-based root canal sealers had their apical sealing, micromorphological aspects, physical characteristics and bond strength to dentin evaluated in this study. For this purpose, seventy-two single-rooted human premolars were endodontically treated. Thirty-three teeth were randomly divided into three groups, externally coated with nail varnish and obturate
