pitting

 [pit´ing]
1. the formation, usually by scarring, of a small depression.
2. the removal from erythrocytes, by the spleen, of such structures as iron granules, without destruction of the cells.
3. remaining indented for a few minutes after removal of firm finger pressure, distinguishing fluid edema (pitting edema) from myxedema. The amount of pitting serves as an assessment of severity and is graded on a numerical scale (see accompanying table).

pit·ting

(pit'ing),
In dentistry, the formation of well defined, relatively deep depressions in a surface, usually used in describing defects in surfaces (often golds, solder joints, or amalgam). It may arise from a variety of causes, although the clinical occurrence is often associated with corrosion.
See also: pitting edema, nail pits.

2 an indentation that remains for a short time after pressing edematous skin with a finger.
3 small depressed scars in the skin or other organ of the body.
4 the removal by the spleen of material from within erythrocytes without damage to the cells.

Patient discussion about pitting

Q. What are the dentists going to do if I have Pit and fissure caries? I look at my teeth and i see tiny black stuff on the fissures of my molars. I am so freakin scared. Are the dentists going to do something painful?

A. Well you will have to see a dentist if you want an answer on what kind of treatment they will offer you. Today dentists use good anesthesia so anything they will do is not supposed to be painful.

Q. tender protuding lymph node lump rt. arm pit aprox. 1/2" dia. any concerns or recommend treatment necessary?

A. lymph nodes can flare up any time you get infected in the armpit and all the area that it drains. i had it several times and it went away in the same manner that it came. i think that sometimes it caused because of a blockade done by deodorant. so i try to use this Chinese salt stone that doesn't contain aluminum.
