Despite the widespread use of ultrasonography (US) in medical diagnostics, there is no similar US device available for visualizing jawbone density. This study is a narrative review of the possible applications of US in dentistry. This review is divided as follows: (a) Pulse-echo ultrasonography: the applications offer new perspectives for periodontal and peri-implant assessment.

Differentiating intraparotid facial nerve schwannoma from other parotid tumors, particularly pleomorphic adenoma, is clinically crucial due to significant differences in treatment approaches. We report a case of a male patient in his 70s presenting with a left parotid mass. Magnetic Resonance Imaging (MRI) revealed a mass within the left parotid gland exhibiting the characteristic ``target sign''.

Regeneration of oral soft tissue defects, including mucogingival defects associated with the recession or loss of gingival and/or mucosal tissues around teeth and implants, is crucial for restoring oral tissue form, function, and health. This study presents a novel approach using three-dimensional (3D) bioprinting to fabricate individualized grafts with precise size, shape, and layer-by-layer cellular organization. A multicomponent polysaccharide/fibrinogen-based bioink is developed, and bioprinting parameters are optimized to create shape-controlled oral soft tissue (gingival) constructs.

Article Synopsis
- The study aimed to explore the use of time-dependent diffusion MRI (dMRI) to differentiate between functioning and nonfunctioning pituitary adenomas (PAs).
- It involved 54 participants, measuring the apparent diffusion coefficients (ADCs) of various types of PAs and finding that the cADC values were significantly higher in functioning PAs compared to nonfunctioning ones.
- The results suggest that cADC is an effective diagnostic tool, particularly for distinguishing growth hormone-producing PAs from nonfunctioning PAs.
Cardiac Arrest during Temporary Clipping for Ruptured Internal Carotid Artery Aneurysm: A Case Report.

Department of Neurosurgery, Matsuyama Shimin Hospital, Matsuyama-city, Ehime, Japan.
Article Synopsis
- Mechanical stimulation of the trigeminal nerve during certain surgeries can lead to serious cardiac events, known as the trigeminal cardiac reflex (TCR), including bradycardia and cardiac arrest.
- A rare case involved a man in his 30s who experienced sinus arrest during surgical clipping of a ruptured aneurysm after stimulation of the trigeminal nerve associated with the internal carotid artery.
- Although cardiac assessments post-surgery showed no abnormalities and no cardiac events occurred over a year and a half, this case highlights the need for further research into the underlying mechanisms and risk factors associated with TCR during such procedures.
