What is supragingival calculus?

Supragingival calculus refers to the hardened deposit of mineralized dental plaque that accumulates above the gum line, often on the surfaces of teeth. This type of calculus is commonly found on the facial surfaces of the upper anterior teeth and on the lingual surfaces of the lower posterior teeth, where salivary flow is more prevalent.

Understanding the characteristics of supragingival calculus is important for dental nursing practice, as its presence can contribute to periodontal disease and may necessitate professional cleaning to maintain oral health. It contrasts with other deposits, such as subgingival calculus, which is found beneath the gum line, or the soft deposits that may not be mineralized. Recognizing supragingival calculus aids in correctly assessing a patient's oral hygiene status and providing appropriate care recommendations.
