a state of unconsciousness from which the patient cannot be aroused, even by powerful stimuli. Traumatic brain injuries are the most frequent cause; other causes include severe uncontrolled diabetes mellitus, liver disease, kidney disease, and neurologic conditions.

Dental Care. A veneer is a thin shield of porcelain that is used to cover the front surface of a tooth. Veneers are designed as a permanent way to change or enhance the look of stained, chipped, broken, or undesired teeth. To get a veneer, you'll very likely need to see your dentist at least two times.
Porcelain veneers are ultra-thin shells of ceramic material which are bonded to the front of the teeth. This procedure can be an ideal choice for improving the appearance of the front teeth by masking discolorations, whitening teeth and/or reshaping a smile.
