Abstract:
This video article presents a case study of a 70-year-old male with medically refractory essential tremor treated with magnetic resonance-guided focused ultrasound (MRgFUS). Following an initial successful ablation of the right thalamus, the patient underwent left-sided thalamotomy. After two tractography-guided sonications, the authors observed a significant reduction in his right-hand tremor with no immediate side effects. Postprocedure evaluation revealed sustained tremor reduction with minimal side effects, showcasing bilateral MRgFUS as an effective, noninvasive option for essential tremor management.

Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
