Xanthic calculus is a term used in the field of dentistry to describe yellow or brown calculus buildup on teeth. The word xanthic is pronounced /ˈzænθɪk/ with a voiceless dental fricative /θ/ and a voiced palato-alveolar fricative /ʒ/ in the final syllable. The spelling of the word is derived from the Greek word "xanthos" meaning yellow. The term calculus refers to hardened mineral deposits that form on teeth, and the combination of these words precisely describes the specific condition.
Xanthic calculus, also known as xanthodontous calculus or yellow calculus, refers to a type of dental calculus that appears as a yellowish or brownish deposit on the teeth. Dental calculus, otherwise known as tartar, is a hardened form of dental plaque that accumulates on the teeth due to inadequate oral hygiene and the mineralization of plaque. Xanthic calculus specifically derives its color from the presence of pigmented substances and pigmented bacteria.
This type of calculus carries certain characteristics and implications for dental health. Xanthic calculus is often more noticeable and visually unattractive than regular, lighter-colored tartar. It tends to form in areas with poor oral hygiene, such as areas affected by gum disease or other oral health issues. The pigmented deposits of xanthic calculus can also serve as a breeding ground for bacteria, potentially increasing the risk of dental infections and inflammations.
The removal of xanthic calculus is typically performed by a dental professional through a process known as scaling. Scaling involves the use of specialized instruments to scrape the calculus off the teeth, both above and below the gum line. This procedure is usually carried out during dental cleaning appointments to prevent the accumulation of calculus from progressing to more severe dental conditions.
Overall, xanthic calculus is a type of dental calculus that exhibits a distinct yellow or brownish color due to the presence of pigmented substances. Identifying and effectively removing this type of calculus is necessary for maintaining good oral health and preventing potential dental complications.

The term "xanthic calculus" is derived from two primary sources:
1. Xanthic: The word "xanthic" originates from the Greek word "xanthos", which means "yellow". It pertains to the yellow color of certain substances.
2. Calculus: The term "calculus" is derived from the Latin word "calculi", which means "pebble". Initially, it referred to small stones that formed in the body, such as kidney stones. Over time, it came to encompass any mineral deposit that forms in biological systems.
Therefore, "xanthic calculus" refers to a yellow-colored mineral deposit or stone that forms in the body. It is typically used in the context of dental or oral health to describe yellowish dental plaque or tartar.
