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.
Dental veneers are wafer-thin, translucent ceramic shells that are placed over the tooth and applied with a special glue. Veneers are predominantly used on the frontal teeth. With the help of veneers aesthetic flaws such as simple tooth misalignments, tooth gaps, unsatisfactory tooth coloration and local discolorations can all be corrected. With veneers, visible tooth surfaces receive an optimized look and even the tooth color is individually corrected through this method.
