Objective: To evaluate the transmittance (%T) and color difference (ΔE*) of six zirconia core materials compared to alumina, over eight colored substrates before and after ceramic application. Methods: Experimental groups (n=5) of standardized disk-shaped cores of alumina, white zirconia, medium-colored zircon...

Objectives: Considering the need for intraoral polishing of zirconia restorations, this in vitro study aimed to 1) evaluate the 2D and 3D surface roughness of different types of ceramic after their finishing and polishing and 2) compare three polishing techniques using three different polishing kits. Methods: Seven...

Objective: To evaluate the influence of the type of cement on the fracture resistance of full-contour resin nanoceramic crowns cemented over preparations with knife-edge margins. Methods: A right lower premolar typodont model was prepared with a 1.5-mm axial reduction, a 2.0-mm occlusal reduction, and a knife-edge v...

Objetivos: Estudar a influência do tipo de bracket estético sobre a resistência ficcional de arcos de aço inoxidável; determinar o efeito da alteração na angulação de segunda ordem entre bracket e fio ortodôntico sobre a fricção produzid...

Objetivo: Comparação da adaptação marginal da obturação com técnica de cone único, utilizando 2 cimentos endodônticos (AH Plus e EndoSequence BC Sealer) e 2 tipos de cones de guta-percha (Protaper F4 e EndoSequence BC Points). Métodos: Vinte e um dent...
