13. Avaliação da retenção de pinos de fibra de vidro reembasados (pinos anatomicos) e não reembasados cimentados em diferentes condições / Evaluation of relined (anatomic post) and non relined fiber glass posts retention cemented in different conditions
This study evaluated the effect of the relining (anatomic posts), of type cements and the length of the luting on the retention of fiber glass posts. One hundred and eighty bovine incisors were selected, their coronary portion removed, and the canals endodontically treated. After endodontic treatment, the canals were extended with diamonds burs nº 4138 and

14. Self-adhesive resin luting : effect of curing mode on degree of conversion, biaxial flexure strength and bond strength to dentin / Cimentos resinosos autoadesivos : efeito do modo de polimerização no grau de conversão, na resistencia flexural biaxial e na resistencia de união a dentina
The use of materials that enable excellence in esthetics, coupled with a reduction in the number of steps in the adhesive luting protocol, have aroused the interest of professionals in the use of self-adhesive resin luting. As these materials have appeared only recently, it is necessary to study the physical and chemical properties as well as the mechanism o

15. Propriedades ópticas e microestrutura de materiais cerâmicos de restauração dentária / Optical properties and microstructure of ceramic materials for dental restoration
The aim of this work was to advance in the understanding of the mechanisms related to the optical behavior of different ceramic materials as a function of thickness, used for dental restoration, to determine the absorption and scattering coefficients and to correlate them to the microstructural characteristics of each material. The masking ability and the co

16. Avaliação ultramorfológica em microscopia eletrônica de transmissão e varredura da interface de união compósito-dentina produzida por diferentes cimentos resinosos convencionais e auto-adesivos
The aim of this study was to evaluate the ultramorphology of the resindentin interfaces produced by different self-adhesive cements submitted to a nanoleakage protocol by means of Transmission (TEM) and Scanning Electron Microscopy (SEM), and to compare them with conventional resin cements. Materials and Methods: Six self-adhesive cements were used in the pr

17. The effect of enamel etching on the in vivo marginal adaptation of indirect composite resin restorations luted with a self-adhesive material / Efeito do condicionamento acido do esmalte na adptação marginal in vivo de restaurações indiretas em resina composta cimentadas com material autoadesivo
In vitro studies have suggested enamel-etching before luting indirect restorations with the self-adhesive cement RelyX Unicem. However, there is no scientific proof that this procedure has any clinical relevance. The aim of this in vivo study was to evaluate the effect of enamel etching on the marginal quality of indirect composite resin restorations (inlay/

18. Resistencia e morfologia da união de cimentos resinosos dual, autopolimerizavel e auto-adesivo a dentina / Bond strength and interface morphology of dual-cure, auto-cure and self-adhesive resin cement to dentin
The aim of this study was to evaluate bond strength and the interface morphology between human dentin and resin cements. Oclusal surfaces of 20 third molars were removed and middle dentin was finished with #600 grit SiC. Circular, 2mm thick, indirect composite resin restorations (Sinfony) were made and sandblasted with aluminum oxide and then silanized. Teet

19. Materiais para cimentação de restaurações protéticas: resposta no tecido subcutâneo de camundongos isogênicos e na polpa de dentes de cães / Luting materials for prosthetic restorations: Response in the subcutaneous tissue of isogenic mice and dogs pulp tissue
The purpose of this study was to evaluate the biocompatibility of different luting agents (Ketac Cem Easy Mix 3M ESPE and RelyX Unicem 3M ESPE), microscopically, by means of implants in the subcutaneous connective tissue of isogenic mice; microscopically and radiographically, after application to deep cavities, close to the pulp, in dogs teeth. In the study

20. Bis-EMA addition influence on physical properties of experimental Bis-GMA/TEGDMA-based resin luting agents / Influencia da adição de bis-ema sobre propriedades fisicas de cimentos resinosos experimentais baseados em bis-GMA e TEGDMA
O objetivo deste estudo foi investigar a influência da adição de Bis-EMA sobre propriedades físicas e mecânicas de cimentos resinosos experimentais à base de Bis- GMA/TEGDMA. A partir da mistura de Bis-GMA e TEGDMA na proporção de 50:50 em peso (R01), o monômero Bis-EMA foi gradualmente incorporado à mistura, 10% em peso por vez, definindo onze for

21. Dental ceramics and the molar crown testing ground
All ceramic crowns are highly esthetic restorations and their popularity has risen with the demand for life-like and cosmetic dentistry. Recent ceramic research has concentrated on developing a fundamental understanding of ceramic damage modes as influenced by microstructure. Dental investigations have elucidated three damage modes for ceramic layers in the

22. Resin cements wear resistance evaluation under brushing abrasion preceded by pH cycling simulations / Resistência ao desgate de cimentos resinosos submetidos à ciclagem de pH e escovação simulada
Indirect aesthetic restorations have been found to have a wide variation on its adaptation, subjecting consequently, the luting material to the oral environment degradation provided by physical, mechanical or chemical processes. Thus, theirwear resistances still worry researchers. In this context, the objective of this work was to evaluate the wear resistanc

23. Avaliação do Desgaste e Rugosidade Superficial de Materiais Utilizados para Selante, Submetidos à Escovação com Dois Diferentes Dentifrícios / WEAR AND SUPERFICIAL ROUGHNESS OF MATERIALS USED AS FISSURES SEALANTS, SUBMITTED TO TOOTHBRUSHING TEST WITH TWO DIFFERENTS DENTIFRICES
The purpose of this study was to evaluate, in vitro, some properties (wear and roughness) of glass ionomers ciment that could influence its indication as pit and fissures sealants. Simultaneously it was evaluated the abrasion of two dentifrices (Tandy and Sorriso) and its influence on the roughness surface. The materials used were Fuji Plus (luting cement),

24. Influencia do tratamento de superficie em uma liga de paladio-prata na resistencia de união de agentes cimentantes
The purpose of this study was to evaluate the influence of four metal surface treatments on the shear bond strength of three luting agents. Cast samples in a disk shape (5 mm in diameter) were made with palladium-silver alloy and grouped in pairs afier ultrasonic cleaning. The pairs were assigned into four groups of 30 each and submitted to the following tre
