Relationship between vertical hyoid bone position and swallowing function in older adults.

Purpose: The purpose of this study was to investigate swallowing function of older adults with lowered hyoid bone position.

Methods: A total of 60 older adults (23 males and 37 females, mean age: 70.1 years) with no diagnosed dysphagia participated in the study.

Evaluation of the effect of reducing metal artifacts in multi-detector CT imaging of zirconia and titanium implants.

Objectives: Zirconia oral implants produce larger artifacts on computed tomography (CT) compared to titanium oral implants. This study aimed to compare the effectiveness of metal artifact reduction (MAR) software and dual-energy (DE) methods, which are used in multi-detector CT (MDCT) to reduce the artifacts produced by titanium and zirconia oral implants.

Methods: Oral implants were placed in the lower right second premolar and second molar regions of an acrylic mandible model and evaluated using MDCT.
