High‐Concentration Hydrogen Peroxide Gels Containing Calcium Polyphosphate Associated With Violet Led Light: Bleaching Efficacy and Effects on Enamel Properties

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate the effect of violet LED light (VL) and hydrogen peroxide (HP) in‐office bleaching gels supplemented with calcium polyphosphate (CaPP) or calcium gluconate (GU): Materials and Methods Bovine enamel blocks (n = 10) were randomly assigned: commercial HP gel, commercial HP gel with GU, or experimental 35% HP with or without

Color stability of precolored and extrinsically colored monolithic multilayered polychromatic zirconia: Effects of surface finishing and aging

Journal of Prosthodontics, EarlyView.
Abstract Purpose To explore the impact of zirconia types, coloring methods, and surface finishing on the color stability of monolithic multilayered polychromatic zirconia after artificial aging, including thermocycling and simulated toothbrushing. Materials and Methods Eighty square‐shaped zirconia samples were divided into 2 types (M3Y‐TZP and M6Y‐PSZ)

Effect of sintering cycle on the strength and translucency of multilayered zirconia

Journal of Prosthodontics, EarlyView.
Abstract Purpose A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated.

Optical stability of 3D‐printed and milled zirconia after artificial aging and immersion in liquids: An in vitro study

Journal of Prosthodontics, EarlyView.
ABSTRACT Purpose To assess the impact of artificial aging and immersion in common liquids on the optical properties of 3D‐printed and milled zirconia. Materials and Methods Monolithic zirconia discs (N = 100) were fabricated using two methods: 3Y‐TZP for milling (e.max ZirCAD LT BL, Ivoclar Vivadent) and printable 3Y‐TZP material (LithaCon 3Y 230) for ...
