A stone, as in the urinary tract, or calcium salt deposits on the teeth. In Latin, the word calculus means 'a pebble.' Pebbles were once used for counting, from which came the mathematical field of calculus.

A stone in the kidney (or lower down in the urinary tract). Also called a kidney stone. The stones themselves are called renal caluli.

  A stone formed in any part of the body, composed of salts of calcium or other materials such as cholesterol.

A small, hard mass or stone formed in the body, as in a kidney or gallbladder, or a hard coating on the surface of the teeth.

N M |counter; small weight; live coal (Def)

Hardened plaque on teeth, requiring scaling to remove.

Commonly referred to as 'the stone', most often found in the bladder (Calculus vesica) (19thC)

the hardened plaque that can form on neglected or prone teeth, commonly known as tartar

Hard deposits of mineralized dental plaque that is attached to crowns and/or roots of teeth.

Hard deposit of mineralized material, or calcified plaque, that adheres to teeth or crowns. (also known as tarter)

n. cálculo

An abnormal concretion occurring mostly in the urinary and biliary tracts, usually composed of mineral Salts. Also called stones.

Abnormal concretion or calcified deposit that Forms around the Teeth or Dental Prostheses.

Stones in the Kidney, usually formed in the urine-collecting area of the Kidney (Kidney Pelvis). Their sizes vary and most contains Calcium Oxalate.

The presence of Calculi in a Salivary Duct or gland.

Presence of small Calculi in the terminal Salivary Ducts (salivary Sand), or stones (larger Calculi) found in the larger ducts.

Calculi occurring in a Salivary Gland. Most Salivary Gland Calculi occur in the Submandibular Gland, but can also occur in the Parotid Gland and in the sublingual and Minor Salivary Glands.

Low-density crystals or stones in any part of the URINARY TRACT. Their chemical compositions often include Calcium Oxalate, Magnesium ammonium phosphate (struvite), Cystine, or Uric Acid.

Stones in the Urinary Bladder; also known as vesical Calculi, Bladder stones, or cystoliths.

If left untreated, plaque can begin to mineralize and harden into calculus or tartar.

Plaque on the surface of the tooth that has mineralised to produce a hard, brown coloured deposit; it's similar to tartar that can build up on human teeth.

Another term for tartar that accumulates on teeth. Calculus is made up of plaque that has become mineralised; is hard and yellow-brown in colour.

 Hard substance that forms on teeth from plaque.

also known as “tartar”

A hard deposit of mineralized substance adhering to crowns and/or roots of teeth or prosthetic devices. Canal

the hardened plaque that can form on neglected or prone teeth, commonly known as tartar

The scientific term for tartar, which is a hard deposit that typically forms due to poor oral hygiene. When plaque mineralizes and hardens it forms calculus. Canal
