13. Bond strength durability of self-etching adhesives and resin cements to dentin
OBJECTIVES: To evaluate the microtensile bond strength (µTBS) of one- (Xeno III, Dentsply) and two-step (Tyrian-One Step Plus, Bisco) self-etching adhesive systems bonded to dentin and cemented to chemically cured (C&B Metabond) or light-cured paste of a dual-cure resin cement (Variolink II, Ivoclar) within a short (24 h) and long period of evaluation (90 d

14. Comparison of the time required for removal of intraradicular cast posts using two Brazilian ultrasound devices
The aim of this in vitro study was to compare the time required for removal of intraradicular cast posts cemented with zinc phosphate (ZF) or glass ionomer cement (GIC), using two Brazilian ultrasound devices (BUD). Seventy two human inferior premolars with single root canals were sectioned transversally at the cementoenamel junction. In each specimen, the r

15. Estudo ex vivo da resistência de união de pinos de fibra às paredes do canal radicular utilizando diferentes cimentos / Ex vivo study of bond strength of fiber posts to root canal using different cements
O objetivo deste estudo foi avaliar ex vivo a resistência de união de pinos de fibra de vidro (FV) e pinos de fibra de carbono (FC) nos terços cervical, médio e apical do canal radicular, cimentados com dois tipos de cimentos resinosos: auto-adesivo (RX) e convencionais (CP). Quarenta caninos superiores foram separados em 4 grupos (n = 10) de acordo com

16. Correlation between margin fit and microleakage in complete crowns cemented with three luting agents
Microleakage can be related to margin misfit. Also, traditional microleakage techniques are time-consuming. This study evaluated the existence of correlation between in vitro margin fit and a new microleakage technique for complete crowns cemented with 3 different luting agents. Thirty human premolars were prepared for full-coverage crowns with a convergence

17. Estudo de variaveis que atuam no processo de cimentação de restaurações ceramicas : atenuação da luz, modos de ativação e tratamento superficial / Study of variables that act in the luting process of ceramic restorations : light attenuation, activation mode, and surface treatment
The durability of ceramic restoration depends of factors like the conversion degree of a luting agent and the interaction of this luting agent with the ceramic internal surface. These in vitro studies evaluate: (1) the influence of different ceramics and the effect of different activation modes on Knoop Hardness Number (KHN) of a dual agent luting, immediate

18. Tensile strenght of NiCr crowns cemented upon usinated titanium alloy abutments, LASER irradiated or not / Resistência à remoção por tração de coroas NiCr cimentadas sobre munhões usinados em liga de titânio, irradiados ou não por LASER
By means of tensile essays, NiCr total crowns were removed from usinated tronco-conical abutments composed by an Ti-6Al-4V alloy; the performance of 4 cementig agents (S. S. White zinc phoshate, Ketac Cem Easymix glass ionomer, RelayX Luting 2 composite resin and Panavia 21 TC special acrylic resin) was evaluated. Among a total of 50 abutments, 40 were used

19. Influência do padrão de evaporação do silano sobre a resistência de união entre uma cerâmica à base de dissilicato de lítio e um cimento resinoso quimicamente ativado: avaliação in vitro através de um ensaio mecânico de microtração
Ceramic-bonded restoration longevity and durability are related with the quality and stability of the bond between the ceramic surface and the luting agent. Microtensile bond strength values have been used to predict the clinical success of these restorations. With the aim to evaluating the influence of silane heat treatment on the bond strength between a ce

20. Avaliação in vitro de restaurações indiretas de composito em dentes deciduos : estudo do tratamento do substrato e agentes de fixação
The indirect restorations are an interesting restoration procedure in the pediatric dentistry clinic, because this leads to a reduced chairside time, besides would decrease polymerization shrinkage due to the resin luting agent lower volume. To endodontically treated teeth, the performance of adhesive restorations has already not been established, and this i

21. Influencia da covergencia axial e do alivio interno na adaptação e resistencia a remoção por tração de coroas totais cimentadas com cimentos resinosos
The objective of this study was to evaluate the influence of axial convergence and relief on the marginal adaptation and retention of cemented complete crowns with Scothbond resin cement (3M) and Enforce resin cement (Dentsply). Sixteen hundred recently extracted bovine incisors were prepared to receive full cast crows, standardized preparations were made an
