In situ evaluation of the bleaching efficacy of experimental hydrogen peroxide hydrogel with MnO‐doped Biosilicate activated by violet LED light

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract Hydrogen peroxide (HP) at 35% is effective for dental bleaching but may reduce enamel mineral content and induce structural changes. This study developed a bleaching‐hydrogel containing 6%HP and manganese‐oxide–doped Biosilicate (MnO_BioS), activated by violet LED, under in situ conditions.

Effect of Occlusal Adjustment and Subsequent Repolishing on the Translucency Parameter, Contact Angle, and Flexural Strength of Different Types of Glazed Monolithic Zirconia

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives This study evaluated the effects of material and surface condition (glazed vs. polished after simulated occlusal adjustment) on translucency parameter, contact angle, and flexural strength of four monolithic zirconia. Materials and Methods Disk‐shaped specimens (n = 80, Ø12 × 1 mm) were fabricated from four monolithic zirconia ...

Fracture Resistance of Extensively Compromised Anterior Teeth Restored With Fiberglass Posts and Biomimetic Protocols: An In Vitro Study

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective Polyethylene fiber (PF) and fiberglass (FG) posts have been recommended for intraradicular anchorage when there is a significant loss of coronal structure. However, few studies have evaluated their performance in anterior teeth combined with direct restorations as an alternative to single crowns.

Method and device for detection of surface discontinuities or defects [PDF]

open access: yes, 1974
Surface discontinuities of defects such as cracks and orifices are detected by applying a penetrating fluid, preferably a liquid, to a test surface so as to cause the liquid to penetrate any minute cracks or opening in the surface, removing the excess ...

Effects of Substructure Color and Restoration Thickness on the Final Color of Ultra‐Translucent Zirconia Ceramics

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study aimed to evaluate the effects of substructure color and restoration thickness on the final color of shade‐gradient ultra‐translucent zirconia ceramics. Material and Methods A total of 180 flat‐shaped ultra‐translucent zirconia specimens (5Y‐PSZ) with thicknesses of 0.4, 0.6, and 0.8 mm (n = 60) were fabricated and
