In dentistry, calculus or tartar is a form of hardened dental plaque. It is caused by precipitation of minerals from saliva and gingival crevicular fluid (GCF) in plaque on the teeth . This process of precipitation kills the bacterial cells within dental plaque, but the rough and hardened surface that is formed provides an ideal surface for ...
Dental cavity, also known as tooth decay, [a] is the breakdown of teeth due to acids produced by bacteria. [6] The resulting cavities may be a number of different colors, from yellow to black. [ 1 ] Symptoms may include pain and difficulty eating.
Dental plaque is a microbial biofilm which forms on teeth. This biofilm may calcify and harden, termed calculus (tartar). Plaque tends to build up around the gingival margin (the gumline) and in gingival crevices or periodontal pocket (below the gumline). The release of waste products from the bacteria living in the biofilm causes an ...
Congenital erythropoietic porphyria (Gunther disease) is a rare congenital form of porphyria, and may be associated with red or brown discolored teeth. [ 1 ] [ 12 ] Hyperbilirubinemia during the years of tooth formation may make bilirubin incorporate into the dental hard tissues, causing yellow-green or blue-green discoloration. [ 1 ]
There are two main methods of detecting dental plaque in the oral cavity: through the application of a disclosing gel or tablet, and/or visually through observation. Plaque detection is usually detected clinically by plaque disclosing agents. Disclosing agents contain dye which turns bright red to indicate plaque build-up. [1]
Congenital erythropoietic porphyria causes porphyrins to be deposited in teeth, causing a red-brown coloration. Blue discoloration may occur with alkaptonuria and rarely with Parkinson's disease . Erythroblastosis fetalis and biliary atresia are diseases which may cause teeth to appear green from the deposition of biliverdin .
The body cavity search Christina Cardenas was subjected to at a correctional facility and hospital in Tehachapi amounted to "state sanctioned torture," famed attorney Gloria Allred said.
Oral and maxillofacial pathology refers to the diseases of the mouth ("oral cavity" or "stoma"), jaws ("maxillae" or "gnath") and related structures such as salivary glands, temporomandibular joints, facial muscles and perioral skin (the skin around the mouth). [1] [2] The mouth is an important organ with many different functions. It is also ...
