Dental Students’ Perceptions of Standardized Patient Experiences Conducted Virtually: A Multi‐Year Qualitative Study

Journal of Dental Education, EarlyView.
ABSTRACT Purpose As teledentistry becomes more common, it is important for students to develop skills in communicating with patients virtually. This study investigated students’ individual communication perceptions and preferences compared to in‐person sessions of participating in standardized patient (SP) exercises in a virtual medium. Methods Between

Augmented Reality of Anatomical Structures of the Maxillomandibular Complex for Learning Dental Radiographic Techniques

Journal of Dental Education, EarlyView.
ABSTRACT Introduction Augmented reality (AR) enables interactive learning in real‐world environments. In dental radiography education, AR offers a promising tool to enhance students' clinical skills by allowing them to simulate and practice procedures before engaging with actual patients. Repeated practice in an AR environment can reinforce theoretical

Exploiting Scattering‐Based Point Spread Functions for Snapshot 5D and Modality‐Switchable Lensless Imaging

Laser &Photonics Reviews, EarlyView.
This paper demonstrates a snapshot 5D and modality‐switchable lensless camera (Diffuser‐mCam), which can encode 2D intensity, multi‐spectral, polarization, and time information into a monochromatic raw data, and subsequently decode it using the compressed sensing algorithm at the sampling rate of 2.5% per channel.
