Restoration of human tooth enamel

BMEMat, EarlyView.
Human tooth enamel has remarkable properties but lacks self‐repair ability. Existing restorative materials cannot fully replicate enamel's microstructure and function, resulting in low restorative efficiency. This review summarizes the formation process and characteristics of enamel, and current restorative materials and future research directions are ...

Classifying the Natural Tooth Color Spaces of Different Ethnic Groups

Color Research &Application, EarlyView.
ABSTRACT This study aimed to classify the natural tooth color spaces of various ethnic groups and assess the coverage error (CE) of the Vita 3D‐Master shade guide. A sample of 490 volunteers from five ethnic backgrounds participated, with inclusion criteria set for adults aged 20– to 45 with healthy, correctly aligned natural teeth free of restorations.

Acoustic Features of Airway Protective Maneuvers as Biomarkers of Radiation‐Associated Dysphagia and Penetration/Aspiration in Head and Neck Cancer Patients

Head &Neck, EarlyView.
ABSTRACT Background This study aimed at identifying acoustic features of airway protective maneuvers as biomarkers of radiation‐associated dysphagia, involving penetration/aspiration and pharyngeal residue. Methods Temporal and spectral acoustical analyses were carried out on voluntary coughs, voluntary throat clearings, and reflexive coughs.

Full‐Field Assessment of Geometry and Collagenous Architecture of Porcine Valve Leaflets via Laser Micrometry and Quantitative Polarized Light Imaging

Journal of Biophotonics, EarlyView.
Despite the frequent failure of aortic valves and pediatric usage of pulmonary valves as a replacement, comparative studies on their collagenous architecture and macroscale geometries are limited. We non‐destructively compared thickness and anisotropy in aortic and pulmonary valve leaflets to better understand the differences between valve types ...

App‐Supported Assessment of Clinical Courses for Dental Students: Discrepancies between Self‐Assessment and Instructor Assessment

Journal of Dental Education, EarlyView.
ABSTRACT Introduction From a student's perspective, assessment plays a central role in education and is essential in a university setting. Developing accurate self‐assessment, without over‐ or underestimating one's abilities, requires practice and is often misaligned with actual skills.
