Assessment Design in the Era of Large Language Models: Evidence From Japanese Health Professions Licensing Examinations

Toshitsugu Sakurai, Daichi Aizawa, Kazuyoshi Ôkawa, Ryo Kofuchi et autres

Background: The rapid development of large language models (LLMs) has raised questions about the continued educational value of conventional assessment formats in health professions education. This study evaluated how examination type, search access, image-based question characteristics, and item format influenced LLM accuracy …

Changes in polymerization stress of self-adhesive resin composites during water storage

Kazuyoshi Ôkawa, Daichi Aizawa, Hiro Matsumoto, Masao Hanabusa et autres

BackgroundResin composite restorations exhibit dimensional changes in the oral environment due to polymerization reaction and/or water sorption, which generates stresses in the surrounding tooth structures. The state of stress may differ between self-adhesive resin composites (SARCs) and conventional resin composites because only …

Effect of thiol compound on the dentin bond strength when using experimental one-bottle self-etch adhesive system

Masao Hanabusa, Kazuyoshi Ôkawa, Nana Sakaeda-Naito, Takatsugu Yamamoto

This study evaluated improvements in the micro-tensile bond strength of a one-bottle adhesive to dentin upon incorporating a thiol compound. Formulations containing 0, 0.1, 0.3 or 0.5% of the thiol were prepared (TH78-0, TH78-0.1, TH78-0.3 and TH78-0.5). Flat dentin surfaces were produced …

Comparison of polymerization stresses of dental resin composites evaluated by two indentation fracture methods

Masao Hanabusa, Saori Kimura, Nana Sakaeda, Kazuyoshi Ôkawa et autres

BACKGROUND: Polymerization stress is a major problem in dental resin composite restorations. Two indentation fracture methods can be applied to evaluate the stress, however, they often calculate different values. OBJECTIVE: To compare polymerization stresses of dental composites determined by the two methods. …

Correlation Between Choroidal Structure and Smoking in Eyes With Central Serous Chorioretinopathy

Tatsuya Inoue, Kazuyoshi Ôkawa, Ryo Asaoka, Keiko Azuma et autres

Abstract A smoking habit is associated with central serous chorioretinopathy (CSC). Although CSC is caused by an abnormal circulation of the choroid, how smoking habit affects the choroid remains elusive. Therefore, to investigate the effect of smoking on the choroidal structure in …
