Effect of MTA-based sealer on the healing of periapical lesions
(2013-05-01)
Some manufacturers have recently added specific components to improve the ease of handling and insertion material properties of MTA in order to create MTA-based sealers. Objective: The aim of this study was to evaluate the ...
Stress distribution on dentin-cement-post interface varying root canal and glass fiber post diameters. A three-dimensional finite element analysis based on micro-C data
(Universidade de São Paulo (USP), Faculdade de Odontologia de Bauru, 2014)
Cementation of fiber post: influence of the cement insertion techniques on the bond strength of the fiber post-root dentin and the quality of the cement layer.
(2010-11-01)
The aim of this study was to assess the influence of resin cement insertion methods on the bond strength of a fiber post to root dentin and quality of the cement layer. Forty bovine single-roots (length =16 mm) were randomly ...
Temperature Changes in Gutta-Percha and Resilon Cones Induced by a Thermomechanical Compaction Technique
(Elsevier B.V., 2009-06-01)
Introduction: The aim of this study was to assess temperature changes in conventional gutta-percha, thermoplastic gutta-percha, and Resilon cones by using thermomechanical compaction technique. Methods: The root canals of ...
Functional and esthetic rehabilitation with In-Ceram alumina and zirconia system: A multidisciplinary approach
(2011-01-01)
The development of all-ceramic systems following metalceramics restorations allowed simulation of natural dentition due to favorable esthetics and resistance. In-Ceram is an alternative when esthetics is primordial as well ...
A comparison of one versus two appointment endodontic therapy in dogs' teeth with apical periodontitis
(Lippincott Williams & Wilkins, 2003-02-01)
This study was conducted to observe the healing process in dogs' teeth with apical periodontitis after root canal treatment in one or two appointments. Premolars and anterior dogs' teeth had their root canals opened to the ...
Apical seal of root canals with gutta-percha points with calcium hydroxide
(Fundação Odontológica de Ribeirão Preto, 2004-01-01)
Foi propósito deste trabalho observar se o uso de cones de guta-percha contendo Ca(OH)2, promove melhora no selamento marginal apical e, também, se apenas o cone principal contendo essa droga produz esse efeito. Assim, ...
Influência de diferentes sistemas adesivos na resistência de união de pinos de fibra à dentina intrarradicular
(2011-07-01)
Objective: To evaluate the influence of three adhesive systems on the bond strength of fiber post luted to root dentine. The hypothesis was that the bond strength is influenced by the adhesive system. Method: The canals ...
