Acquired cuticle
A layer of salivary products, bacteria, and food debris on the surface of the teeth; not a true cuticle.
-
Cutaneous radiation syndrome
The damaging effects of radiation exposure on the skin. In limited exposures, CRS may be limited to mild sun-burning. Blistering, hair loss, necrosis, or permanent scarring may occur with more extensive exposures.
-
Cutaneous nerves
Nerves that provide sensory pathways for stimuli to the skin.

Wheelchair cushion
A padded surface for wheelchair seats designed to prevent pressure sores. There are several static varieties, including air-filled, polyurethane foam, and flotation, the latter filled with water or gel. Dynamic surfaces, which require an external power source, protect pressure points by alternating high and low air pressures through a system of valves and pumps.
-
Cushing response
A reflex due to cerebral ischemia that causes an increase in systemic blood pressure. This maintains cerebral perfusion during increased intracranial pressure.

Curve of carus
An arc corresponding to the pelvic axis. At the end of the second stage of labor, when the fetal head reaches the curve of Carus, it is directed upward toward the vaginal introitus and forced into extension by the resistance of the pelvic floor.
-
Time-temperature cooling curve
The mathematical relation that plots the physical and chemical behaviors of dental (and other) materials as their temperature decreases over time.
-
Sensitometric curve
In radiographic film analysis, the curve derived by graphing the exposure to the film versus the film density. Analysis yields information about the contrast, speed, latitude, and maximum and minimum densities of the film or film-screen system. Digital radiography systems exhibit linear curves.
-
Epidemic curve
A chart or graph in which the number of new cases of an illness is plotted over time.
