What is the color of subgingival calculus?

What is the color of subgingival calculus?

Subgingival calculus is most often brown, black or green in color from its chronic exposure to gingival crevicular fluid, blood and blood breakdown products. It is frequently associated with the development of the pyogenic granuloma, an epulis-like lesion on the gingiva.

What tooth surface does subgingival calculus most frequently occur?

For the lingual surfaces of the teeth, the lower first molars have the most subgingival calculus. For the buccal surfaces of the teeth, the mandibular anterior teeth and maxillary molar teeth have the greatest amount of subgingival calculus.

Can you see subgingival calculus?

Characteristics of Subgingival Calculus But the tartar that forms below the gumline — and is therefore not immediately visible — is known as subgingival calculus. This type of calculus is usually dark brown to greenish black in color and can be detected with a dental instrument called an explorer.

What is the difference between supra and subgingival 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).

What does calculus look like on teeth?

Dental plaque forms on your teeth from food debris and bacteria and looks like a yellow pale substance that is first visible in between your teeth and then around the surface as it grows. When dental plaque continues to build, something called tartar, or dental calculus starts to appear.

Which clinical characteristic indicates the presence of subgingival calculus?

Terms in this set (12) Which clinical characteristic indicates the presence of subgingival calculus? Radiographically what is the radiopaque structure posterior to tooth #31?

What is subgingival calculus quizlet?

Terms in this set (24) Subgingival deposits. calculus deposits located apical to the gingival margin and can also be called submarginal or serumal calculus.

Can calculus be seen on radiograph?

Evaluation of calculus by conventional radiography showed low sensitivity: radiographic deposits were detected on only 44% of surfaces that demonstrated calculus microscopically. Specificity was high and the rate of false positives was only 7.5%.

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

[3,4] The reason for the increase in damage is that the calculus facilitates further bacterial involvement by forming a rough surface for colonization, and therefore serves as a predisposing factor in pocket development. …

What is Supragingival and subgingival 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.

What is subgingival tartar?

Subgingival tartar is located at the root of the tooth below the gum and is not visible to the naked eye. This subgingival tartar is the most dangerous, since it is one of the causes of periodontal disease. In order to detect this tartar, it is important to perform x-rays and a periodontal probing.

What is subgingival and supragingival calculus?

What is the source of minerals for subgingival calculus formation?

Saliva is the mineral source for calcification of supragingival calculus, while the gingival crevicular fluid provides minerals for the mineralization of sub- gingival deposits.

What is subgingival scaling?

Subgingival scaling involves the removal of subgingival calculus from the tooth surface. This can be from the enamel (crown) or from the root cementum surface, in which case it is termed root planing.

What is the color of supragingival calculus?

Unlike subgingival calculus, supragingival calculus can be easily identified during clinical examinations: its color ranges from creamywhite to yellow or brown, distinguishing it from the surface of the enamel (7).

What is the composition of subgingival calculus?

By contrast, subgingival calculus is mainly found on the interproximal and lingual tooth surfaces, being randomly distributed throughout the mouth. 36 Composition Approximately 80% (dry weight) of calculus is mineralized material (hydroxyapatite) and 20% comprise organic compounds.
