1. Effect of rewetting solutions on micropush-out dentin bond strength of new bioceramic endodontic material
Abstract To evaluate the influence of rewetting solutions on bond strength to root dentin of conventional gutta-percha (GP) or niobium phosphate glass-based gutta-percha (GNb) associated with a bioceramic sealer. The root canals of 80 human mandibular premolars were prepared using nickel-titanium instruments and irrigation with sodium hypochlorite and EDTA.

2. COMPARAÇÃO DE DIFERENTES ENSAIOS MECÂNICOS PARA AVALIAR A RESISTÊNCIA ADESIVA A UMA CERÂMICA Y-TZP / COMPARISON OF DIFFERENTS MECHANICAL TESTS TO EVALUATE THE BOND STRENGTH TO A Y-TZP CERAMIC
This study aimed to evaluate the bond strength using different test types for bonding evaluation, between a yttrium tetragonal zirconia polycrystals (Y-TZP) ceramic and composite resin, considering two types of Y-TZP surface treatments. Three hundred and sixty Y-TZP blocks, received one of the two surface treatments (N= 180): UT- control (untreated) and SS-

3. Análise mecânica de retentores intra-radiculares / Mechanical analysis of endodontic post
The fiber-reinforcement composite (FRC) posts introduced the new concept of restorative system, in which the various components of the reconstruction: post, cement, filling material and dentin have now become a complex mechanically homogeneous. The knowledge of the structure, composition and physical properties of these fiber posts systems is important in or

4. Avaliação comparativa pelos testes micropush-out e micro-cisalhamento da resistência adesiva de restaurações diretas de resina composta usando diferentes sistemas adesivos
The bond strength may be influenced by the different composition and manipulation of the adhesive systems, the dentin structure and the method of evaluation. After exposure of the occlusal dentin surface 160 third human molars were divided in 2 groups (n=80) for the micropush-out (μPBS) and microshear (μSBS) bond strength tests. For the μPBS,

5. Efeito do tipo de cimento de fixação e configurações de retentores intra-radiculares na adesão à dentina radicular em diferentes profundidades
Este estudo avaliou o efeito do tipo de cimento de fixação e da configuração de retentores intra-radiculares na adesão à dentina intra-radicular em diferentes profundidades. Cento e vinte raízes receberam tratamento endodôntico e foram aliviadas para fixação de retentores intra-radiculares de fibra de vidro nas configurações: serrilhado/paralelo
