LDL cholesterol sometimes is called âbadâ cholesterol. A high LDL level leads to a buildup of cholesterol in your arteries. (Arteries are blood vessels that carry blood from your heart to your body.) HDL cholesterol sometimes is called âgoodâ cholesterol. This is because it carries cholesterol from other parts of your body back to your liver.
Spacers are usually used to put spaces in between teeth before braces are established. It can be agitating or painful, but patients are often warned not to pick at them or they will fall out. They are usually rubber, but sometimes they can be metal. They can be used when a patient's teeth are too close together.
The premolar teeth, or bicuspids, are transitional teeth located between the canine and molar teeth. In humans, there are two premolars per quadrant in the permanent set of teeth, making eight premolars total in the mouth. They have at least two cusps. Premolars can be considered as 'transitional teeth' during chewing, or mastication.
