Study Notes

Dental Calculus Definition

Dental calculus is a hard, calcified deposit that forms on teeth.

Dental Calculus Locations

Dental calculus can be found on both the tooth's crown (supragingival calculus) and the root (subgingival calculus).

Dental Calculus Composition

Dental calculus is primarily made up of inorganic materials, including calcium phosphates, calcium carbonates, and magnesium phosphates.
It also contains organic components like proteins, carbohydrates, and lipids.

Dental Calculus Crystalline Structure

Dental calculus has a crystalline structure, with the primary form being hydroxyapatite.
The crystals in dental calculus are very small, and they are arranged in a random, non-uniform pattern.
