What is a Supragingival calculus?

Tartar that accumulates on your teeth above the gumline and is easily seen by your dentist or dental hygienist is called supragingival calculus, according to the IJDHS article. But the tartar that forms below the gumline — and is therefore not immediately visible — is known as subgingival calculus.

How are Calcular deposits formed?

Calculus formation is the result of petrification of dental plaque biofilm, with mineral ions provided by bathing saliva or crevicular fluids. Supragingival calculus formation can be controlled by chemical mineralization inhibitors, applied in toothpastes or mouthrinses.

Where are subgingival calculus deposits located?

Clinically, calculus is described according to its location: the most common is supragingival, occurring just at or above the gum margins opposite the openings of major salivary ducts. Subgingival calculus forms below the gum line on the surfaces of the tooth root, at sites of periodontitis.

Does calculus directly cause gingival inflammation?

Plaque accumulation causes the gingiva to become irritated and inflamed, and this is referred to as gingivitis. When the gingiva become so irritated that there is a loss of the connective tissue fibers that attach the gums to the teeth and bone that surrounds the tooth, this is known as periodontitis.

What is the difference between subgingival and supragingival calculus?

Types of Calculus The parts of your hand and wrist that extend visibly outside the sleeve would be considered supragingival (above the gumline), whereas anything unseen below the sleeve would be considered subgingival (below the gumline). Calculus above the gumline can appear whitish or yellowish in color.

What does subgingival mean?

Subgingival means below the gum line (sub = below, gingival = of or relating to the gums). Calculus is a form of hardened dental plaque. It is caused by the condensation of saliva minerals and the fluid produced in the crevices of our gums.

What are Calcular deposits?

Calcular Deposits, also known as Tartar or Dental Calculus, are usually hard yellow or brown deposits that collect at the neck area of the teeth at the gum line, and between the teeth. Calcular deposits cause gums to inflame and bleed in a condition known as Gingivitis (gum disease).

Why is subgingival calculus a problem?

Lacking good oral hygiene, plaque will not only build up but calcify into dental calculus, which is often called tartar. Calculus can be either supragingival—above the gumline—or subgingival—below the gumline. Subgingival calculus can result in gum disease and eventually tooth loss.

Why is subgingival calculus considered a predisposing factor in pocket development?

-subgingival biofilm contains pathogenic bacteria that cause inflammation and destruction in the soft tissue and lead to loss of attachment to the tooth surface and development and deepening of the pocket.

How do you do subgingival scaling?

For subgingival scaling with hand instruments, use a subgingival curette (e.g. Gracey curette SG 11/12 or 13/14). Place the blade at 45°-90° to the root surface and pull firmly against the tissue to remove as much debris and chronically inflamed tissue as possible.

What’s the difference between subgingival and Supragingival calculus?

The parts of your hand and wrist that extend visibly outside the sleeve would be considered supragingival (above the gumline), whereas anything unseen below the sleeve would be considered subgingival (below the gumline). Calculus above the gumline can appear whitish or yellowish in color.

What’s the difference between supragingival and sub gingival crystal forms?

Differences in Composition of Crystals between Supra Gingival and Sub Gingival calculus: The inorganic composition of subgingival calculus is similar to that of supragingival calculus, with some differences.

What are the different types of dental calculus?

According to the IJDHS review, there are two types of dental calculus: supragingival and subgingival. The difference between the two types is the location of the calculus relative to the edge of the gum tissue.

Which is the most common crystal form in supragingival calculus?

Generally, 2 or more crystal forms are typically in a sample of calculus. Hydroxyapatite and Octacalcium Phosphate are detected most frequently i.e 97% to 100% of all supragingival calculus. Differences in Composition of Crystals between Supra Gingival and Sub Gingival calculus:
