1. Radiopacidade de materiais restauradores estéticos / Radiopacity of esthetic restorative materials
A radiopacidade é um requisito essencial para a boa qualidade de um material restaurador estético, pois está diretamente relacionada à adaptação marginal. Nosso objetivo foi avaliar a radiopacidade de 28 marcas de resinas fotopolimerizáveis de uso direto existentes no mercado e compará-las com a radiopacidade do esmalte, da dentina e com a espessura

2. Efeito da escovação e do envelhecimento artificial acelerado sobre a alteração superficial de materiais restauradores estéticos / Effect of simulated toothbrushing and accelerated artificial aging on surface degradation of aesthetic restorative materials
O objetivo desse estudo foi avaliar sistematicamente o efeito da escovação simulada e do envelhecimento artificial acelerado (EAA) sobre estabilidade de cor e rugosidade de superfície de compósitos odontológicos de nanopartículas (Z350 - 3M ESPE) e híbrido (Tetric N-Ceram - Ivoclar Vivadent). Foram confeccionados 24 corpos-de-prova (12mm de diâmetro

3. Effects of air-polishing powders on color stability of composite resins
OBJECTIVES: The purpose of this study was to investigate the effect of different air-polishing powders on the color stability of different types of composite resin restorative materials. MATERIAL AND METHODS: Thirty cylindrical specimens (15×2 mm) were prepared for each of 7 composite resin restorative materials. All specimens were polished with a series of

4. Alterações nas caracteristicas da superficie de compositos restauradores sumetidas a diferentes tecnicas de acabamento e polimento / Changes in surface characteristics of restorative composites subjected to different techniques for finishing and polishing
Several changes were made in the light-cured composites resins manufacture, especially trying to obtain better color stability, adequate wear resistance and clinically acceptable surface smoothness. About this, manufacturers have predominantly reduced the diameter of charged particles, promoting changes in its geometry and also incorporating a bigger amount

5. Analysis of data from digital intraoral spectrophotometer of two dental porcelain after different surface treatments / Análise dos dados obtidos com o uso do espectrofotômetro digital intraoral de duas porcelanas dentais após diferentes tratamento de superfície
Considering the current aesthetic aspect, the harmony between the color of the tooth and dental restorative materials is one of the issues of greatest importance and technical difficulty. The use of apparatus for the selection of color by digital method proposes to reduce the subjective aspect of the vision of colors, thus minimizing possible failures of the

6. Color stability evaluation of aesthetic restorative materials
Color match is one of the most important characteristics of aesthetic restorative materials. Maintenance of color throughout the functional lifetime of restorations is important for the durability of treatment. This characteristic is not constant among dental materials. The purpose of this research was to assess the color stability of five aesthetic restorat

7. Influência do envelhecimento artificial acelerada sobre a estabilidade de cor, opacidade e densidade das ligações cruzadas de compósitos odontológicos armazenados em diferentes ambientes e tempos de armazenagem / Influence of artificial accelerated aging on color stability, opacity and cross-link density of dental composites stored in different environment and over different times
The evolution of composite resins, allied to their characteristic of restoring the natural appearance of teeth regarding color and opacity, makes them one of the main materials of choice among the restorative materials used in dentistry. Color and opacity stability assume a crucial role in a successful aesthetic restoration treatment, since changes in these

8. New monomers obtained from glycidyl methacrylate, bisphenol A and 4,4-isopropylidenedicyclohexanol: synthesis, structural characterization and properties of composites for use as dental composite resins / Novos monômeros obtidos a partir do metacrilato de glicidila, bisfenol A e 4, 4 isopropilidenodicicloexanol : síntese, caracterização estrutural e propriedades de compósitos para utilização em resinas de restauração dental
Nowadays, composite resins are the direct restorative materials more important in dental clinical performance, due to their versatility and aesthetic excellence. Bis-GMA (2,2-bis[4(2-hydroxy-3-metacryloxypropoxy)phenil]propane) is the base monomer more frequently used in restorative composite resins. However, this monomer presents some disadvantages, such as

9. Avaliação espectrofotométrica da estabilidade de cor de materiais restauradores estéticos
Color match is one of the most important characteristics of the aesthetics restorative materials. Color stability is a demanding characteristic of the restorative material as though as it indicates its chemical stability. The purpose of this research is to verify the color stability of five aesthetic restorative materials when immersed in coffee solution and

10. 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
