Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),

Application of Baicalein Solution as a Novel Antioxidant After Bleaching: Analysis of Its Effects on Immediate Color Stability and the Reestablishment of Bond Strength in Bleached Enamel

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the antioxidant capacity of the baicalein solution (BA), as well as its effect when applied for different times to the surface of bleached dental enamel, considering immediate color stability and bond strength. Materials and Methods Bovine enamel/dentin specimens (4 × 4 × 3 mm) were randomly divided into five groups (n ...
