Heavy staining and calculus deposits exhibited on the lingual surface of the mandibular anterior teeth, along the gumline Calculus deposit (indicated with a red arrow) on x-ray image In dentistry , calculus or tartar is a form of hardened dental plaque .
Calcification can manifest itself in many ways in the body depending on the location. In the pulpal structure of a tooth, calcification often presents asymptomatically, and is diagnosed as an incidental finding during radiographic interpretation. Individual teeth with calcified pulp will typically respond negatively to vitality testing; te
A cementicle is a small, spherical or ovoid calcified mass embedded within or attached to the cementum layer on the root surface of a tooth, or lying free within the periodontal ligament. [1] [2] They tend to occur in elderly individuals. [3] [4] There are 3 types: [5] [6] Free cementicle – not attached to cementum [5]
Pulp stones are discrete calcifications found in the pulp chamber of the tooth which may undergo changes to become diffuse pulp calcifications such as dystrophic calcification. [2] They are usually noticed by radiographic examination and appeared as round or ovoid radiopaque lesions. [ 3 ]
Essential nutrients for a healthy tooth include calcium, phosphorus, and vitamins A, C, and D. [54] Calcium and phosphorus are needed to properly form the hydroxyapatite crystals, and their levels in the blood are maintained by Vitamin D. Vitamin A is necessary for the formation of keratin, as Vitamin C is for collagen. Fluoride, although not a ...
Some experts also agree on a third type of cementum, afibrillar cementum, which sometimes extends onto the enamel of the tooth. The excessive buildup of cementum on the roots of a tooth is a pathological condition known as hypercementosis. Cementum thickness can increase on the root end to compensate for attritional wear of the occlusal/incisal ...
Calcifying odontogenic cyst (COC) is a rare developmental lesion that comes from odontogenic epithelium. [2] It is also known as a calcifying cystic odontogenic tumor, which is a proliferation of odontogenic epithelium and scattered nest of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass.
The enamel on primary teeth has a more opaque crystalline form and thus appears whiter than on permanent teeth. The large amount of mineral in enamel accounts not only for its strength but also for its brittleness. [6] Tooth enamel ranks 5 on Mohs hardness scale (between steel and titanium) and has a Young's modulus of 83 GPa. [4]
