cal·cu·lus (klky-ls)
n. pl. cal·cu·lus·es or cal·cu·li (-l)
1. An abnormal concretion in the body, usually formed of mineral salts and most commonly found in the gallbladder, kidney, or urinary bladder. Also called stone.
2. Dental tartar.

Calculus
Any type of hard concretion (stone) in the body, but usually found in the gallbladder, pancreas and kidneys. They are formed by the accumulation of excess mineral salts and other organic material such as blood or mucous. Calculi (pl.) can cause problems by lodging in and obstructing the proper flow of fluids, such as bile to the intestines or urine to the bladder.

calculus
[kal′kyələs] pl. calculi
Etymology: L, little stone
1 also called stone. an abnormal stone formed in body tissues by an accumulation of mineral salts. Calculi are usually found in biliary and urinary tracts. Kinds of calculi include biliary calculus and renal calculus.
2 (in dentistry) also called tartar. A deposit of calcium phosphate, calcium carbonate, and organic matter that accumulates on the teeth or a dental prosthesis. Calculus that forms coronal to the gingival crest, called supragingival calculus, is chalky and cream-colored but may be stained by tobacco and food. Calculus that forms in the gingival pocket, or the periodontal pocket, called serumal calculus, subgingival calculus, or veneer, is usually denser and darker than supragingival calculus; it harbors bacteria, thus contributing to periodontal disease.

calculus (dental) (kal´kyls),
n a hard deposit on the exposed surfaces of the teeth and any oral prosthesis within the oral cavity. It is composed of calcium phosphate, calcium carbonate, magnesium phosphate, and other elements within an organic matrix composed of plaque, desquamated epithelium, mucin, microorganisms, and other debris. Factor in the initiation and continuation of periodontal disease. The colloquial term is tartar.

Advanced calculus.
calculus, identification of, by air application,
n the use of compressed air to dry the periodontium and visualize minimal amounts of calculus, which are otherwise difficult to see, especially subgingivally.
calculus record,
n a written accounting of the number and distribution of calculus deposits on tooth surfaces that becomes part of the patient's permanent chart and is used to monitor progress and plan treatment.
calculus, subgingival,
n the calculus deposited on the tooth structure and found apical to the gingival margin within the periodontal pocket. Usually darker and denser than supragingival calculus. Older term is
serumal calculus.
calculus, supragingival,
n the calculus deposited on the teeth coronal to the gingival margin. Usually lighter in color (unless stained) and less dense than subgingival calculus. Older term is
salivary calculus.

calculus
pl. calculi [L.] an abnormal concretion, usually composed of mineral salts, occurring within the animal body, chiefly in the hollow organs or their passages. Called also stones, as in kidney stones (urolithiasis) and gallstones. See also hippomanes.

biliary calculus
a gallstone.
bronchial calculus
see bronchial calculus.
dental calculus
mineralized deposits of calcium phosphate and carbonate, with organic matter, deposited on tooth surfaces. Found commonly in dogs and cats, sometimes in horses, rarely in sheep. May initiate caries and peridontal disease.
lung calculus
a concretion formed in the bronchi. See also bronchial calculus.
pancreatic calculus
very small (4 to 5 mm) calculi in pancreatic ducts, rare and of no pathogenic importance.
prostatic calculus
concretions of calcium phosphates and carbonates in the prostatic ducts are rare and of no clinical significance.
renal calculus
salivary calculus
white, hard, laminated concretions in the salivary duct; a sialolith. Occurs most commonly in horses.
urethral calculus
a calculus lodged in the urethra causes obstruction of the urethra with a potential for causing rupture of the bladder or perforation of the urethra and leaking of urine into subcutaneous or retroperitoneal sites. See also urolith, urolithiasis.
urinary calculus
a calculus in any part of the urinary tract. See urolithiasis.
vesical calculus
a urolith in the urinary bladder.

calculus
Plural, calculi Dentistry Tartar Indurated, yellow–brown/black deposits on teeth formed by bacteria in dental plaques from mineralized calcium salts in saliva and subgingival transudates Kidneys A stone in the urinary tract. See Mulberry calculus, Staghorn calculus.

Patient discussion about Differential and Integral Calculus.

Q. Would kidney stones affect a PSA reading? Would drinking lots of grapefruit juice affect a PSA reading? My husband's PSA reading jumped from a 4.2 to a 17 in @ 2 years' time. How can that be? This man takes all sorts of supplements and really watches his diet. He also takes good care of his body, and does NOT look or act 68.

A. You should get your parathyroid gland checked out. Your calcium level might be causing the kidney stones.

Q. how do i cure tonsil stones (tonsiloth)?

A. There are very little literature about this subject, but I heard about treatment in which the crypts (deep and narrow grooves on the tongue in which the stones form) are burned with laser.

As far as I know these stones don't cause damage by themselves so it's not such a common treatment.

Q. How can i overcome kidney ache? in the morning it appears.after wake up.

A. First of all, it is important to distinguish kidney ache from lower back ache. If you have ever suffered from kidney problems or infections, it might be advisable to see a doctor, and rule out an infection. However, if you are otherwise healthy, and have been experiencing back pain after you wake up, it is very much possible your pain is not from the kidneys, but from the muscles of your back. In this case, some exercise on a daily basis to help strengthen your lower back can very much ease the pain you're experiencing.
