Which term is another name for calculus?

• A. Tartar
• B. Radiograph
• C. Space Maintainer
• D. Periodontal

Answer: (A)

Calculus, in dentistry, is another name for tartar—the hard, mineralized layer that forms when dental plaque isn’t removed and minerals from saliva crystallize on tooth surfaces. This buildup can occur above the gum line (supragingival) or below it (subgingival) and is what cleaners and scaling aim to remove. The other terms refer to different concepts: a radiograph is an X-ray image of the teeth and jaw; a space maintainer is an appliance used to keep a space open for a erupting tooth; and periodontal relates to the supporting structures around the teeth, like gums and bone.
