Objectives: Commercial photocurable polymers used in dental additive manufacturing still have mechanical limitations. The incorporation of graphene may provide interesting advantages in this field. This study aimed to evaluate in vitro the effect of adding graphene nanoparticles to a 3D-printed polymethylmethacrylat...

Objectives: To evaluate the microhardness and flexural strength of printed and conventionally produced denture base acrylic resins. Methods: A total of 32 parallelepiped specimens (64×10×3.3 mm) were manufactured using two light-cured resins suitable for 3D printing (V-Print Dentbase and Denture 3D+) and ...

Objectives: The purpose of this study was to evaluate the effect of mouthwashes on com- posite Knoop microhardness, and to assess the influence of the contact with mouthwashes and mechanical surface treatment on the shear bond strength of repaired composite resins. Methods: One hundred twenty composite resin (Gran...

Objectives: To evaluate the effect of chlorhexidine incorporation on the microhardness and flexural strength of three reline acrylic resins, after a 28-day chemical aging process. Methods: Forty-eight specimens were fabricated according to the several possible combinations of acrylic reline resin and concentrations ...

Objectives: To evaluate the effect of chlorhexidine loading in microhardness and flexural strength of acrylic reline resins, after thermal aging. Methods: Several concentrations of chlorhexidine were selected to load three acrylic reline resins: 1%, 2.5%, 5%, and 7.5% in Kooliner, 1%, 2.5%, 5%, 7.5% and 10% in Ufi G...
