25. Cytotoxicity evaluation of two root canal sealers and a commercial calcium hydroxide paste on THP1 cell line by Trypan Blue assay
OBJECTIVE: The aim of this investigation was to evaluate the cytotoxicity of two brands of root canal sealers, epoxy-resin based and zinc oxide-eugenol based, and one commercial calcium hydroxide paste on a monocyte cell line THP-1. MATERIAL AND METHODS: Undiluted (crude extract) and diluted extracts to 10%, 1%, 0.1%, 0.01%, 0.001% and 0.0001% of the sealers

26. Analysis of inorganic composition and release of formaldehyde after manipulation of endodontic sealers / Analise da composição inorganica e da liberação de formaldeido apos a manipulação de cimentos endonticos
This study evaluated chemical composition (inorganic) and formaldehyde presence in root-canal sealers. Seven root-canal sealers were chosen: four based-zinc-oxide-eugenol (ZOE) (Targer Canal Sealer, Konne; Endo Fill, Dentsply; Endométhasone N, Septodont and; Pulp Canal Sealer, Kerr); two based-mineral trioxide aggregate (MTA) (Endo CPM Sealer, EGEO Dental a

27. Influência da aplicação de selantes de superfície na rugosidade de resinas compostas / Surface sealant application influence on the resin composite roughness.
This in vitro study evaluated the influence of the application of four surface sealers on the surface roughness of composite resins. Fifty specimens were divided into ten groups according to different patterns of composite resin and surface sealers, as follows: G1. Control with Concept resin; G2. Concept + Fortify; G3. Concept + Biscover; G4. Concept + Lasti

28. Evaluation of periapical inflammation response from coronal leakage in dog´s teeth obturated using different resin-based sealers and different obturation techniques / Avaliação da resposta inflamatória periapical resultante da infiltração coronária em dentes de cães obturados com diferentes cimentos resinosos e técnicas obturadoras
Considering the need for three-dimensional obturations and adequate marginal sealing of the radicular canal system as being decisive factors for successful endodontic therapy, this study had as its objective the evaluation of periapical inflammatory responses resulting from coronary infiltration in dogs teeth obturated using different resin sealers (AH Plus,

29. 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

30. 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

31. 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

32. Avaliação da retenção de pinos intra-radiculares fixados com cimento resinoso e de fosfato de zinco, em dentes obturados com cimento à base de óxido de zinco e eugenol, em diferentes períodos entre a obturação e preparo protético/ cimentação dos pinos / Evaluation of intra-radicular posts fixed with resin cement and zinc phosphate cement, in teeth sealed with zinc oxide and eugenol-based sealers, at different periods between the obturation and prosthetic preparation/post cementation
In this study, it was evaluated in vitro the retention of intraradicular posts cemented with resinous sealer and zinc phosphate sealer, in teeth obtured with zinc oxide eugenol-based cement, in different periods between the obturation, preparation procedure of the prosthetic space and posts cementation, by means of tensile test. Sixty superior canines had th
