Effect of Glazing Dwell Time and Cooling Duration on Flexural Strength and Surface Microhardness of 3 mol% Yttria‐Stabilized Tetragonal Zirconia: An In Vitro Study

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of glazing dwell time and cooling duration on the flexural strength and surface microhardness of high‐translucency 3 mol% yttria‐stabilized tetragonal zirconia polycrystal (3Y‐TZP). Materials and Methods Total of 108 rectangular zirconia specimens (20 × 4 × 2 mm) were fabricated from preshaded monolithic blocks

Improving classifier decision boundaries and interpretability using nearest neighbors

Discover Artificial Intelligence
Neural networks often fail to learn optimal decision boundaries. In this study, we show that these boundaries are typically situated in regions with low training data density, making them highly sensitive to a small number of samples, which, in turn ...

Influence of Universal Adhesives With or Without Silane Compared to One‐Step and Two‐Step Silane Agents on Bond Strength to Lithium Disilicate

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the microshear bond strength (μSBS) to lithium disilicate achieved with universal adhesives (with and without silane) compared with one‐step and two‐step silanes, immediately (IM) and after thermocycling (TC). Chemical interaction (CI) was also assessed.

Air‐Abrasion With Aluminum Oxide Particles in Non‐Carious Cervical Lesions: Impact on Sclerotic Superficial Layer, Surface Topography, and Restorative Adhesive Performance

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of airborne‐particle abrasion (APA) with aluminum oxide on superficial dentin sclerosis, surface topography, and bonding performance of a universal adhesive in natural non‐carious cervical lesions (NCCLs), using dentin classification by the North Carolina Index (NCI) and Optical Coherence Tomography Index (OCT).
