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.
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.
It begins at the surface, and may progress into either cavitation (tooth decay) or erosion (tooth wear). Tooth decay demineralization is caused by acids from bacteria in the dental plaque biofilm whilst tooth wear is caused by acids from non-bacterial sources. These can be extrinsic in source, such as carbonated drinks, or intrinsic acids ...
Remineralisation of tooth enamel involves the reintroduction of mineral ions into demineralised enamel. [21] Hydroxyapatite is the main mineral component of enamel in teeth. [22] During demineralisation, calcium and phosphorus ions are drawn out from the hydroxyapatite.
Turner's hypoplasia or Turner's tooth is a presentation of enamel hypoplasia that normally affects only a single tooth. Its causes can be the same as other forms of enamel hypoplasia, but it is most commonly associated with trauma to a primary maxillary central incisor and the subsequent developmental disturbance of the underlying permanent ...
According to a recent study, baby teeth contain an abundance of stem cells, a very special type of cell that can potentially grow replacement tissue in the body and cure a number of diseases.
These deposits are commonly found on teeth or dental appliances such as orthodontic brackets. The most common way dental plaque is assessed is through dental assessment in the dental clinic where dental instruments are able to scrape up some plaque. The most common areas where patients find plaque are between the teeth and along the cervical ...
Calcification of soft tissue (arteries, cartilage, heart valves, [1] [2] etc.) can be caused by vitamin K 2 deficiency or by poor calcium absorption due to a high calcium/vitamin D ratio. This can occur with or without a mineral imbalance. A common misconception is that calcification is caused by excess amount of calcium in diet. Dietary ...
