Severe fluorosis is characterized by brown discoloration and discrete or confluent pitting; brown stains are widespread and teeth often present a corroded-looking appearance. [ 1 ] People with fluorosis are relatively resistant to dental caries (tooth decay caused by bacteria), [ 2 ] although there may be cosmetic concern. [ 2 ]
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 ...
One of the most common types, pitting enamel hypoplasia (PEH), ranges from small circular pinpricks to larger irregular depressions. [2] Pits also vary in how they occur on a tooth surface, some forming rows and others more randomly scattered. [3] PEH can be associated with other types of hypoplasia, but it is often the only defect observed. [4]
Discoloured teeth - teeth may be amber, brown, blue or opalescent; Bulbous shape to the tooth crown due to cervical constriction; Tooth wear/Non-carious tooth surface loss (NCTSL) - due to the poorly mineralised dentine, the enamel of the tooth is unsupported and subsequently shears or chips off as it is subjected to biting forces. This exposes ...
(A) A small spot of decay visible on the surface of a tooth. (B) The radiograph reveals an extensive region of demineralization within the dentin (arrows). (C) A hole is discovered on the side of the tooth at the beginning of decay removal. (D) All decay removed; ready for a filling. A person experiencing caries may not be aware of the disease ...
Dental plaque is a biofilm of microorganisms (mostly bacteria, but also fungi) that grows on surfaces within the mouth.It is a sticky colorless deposit at first, but when it forms tartar, it is often brown or pale yellow.
Molar incisor hypomineralisation (MIH) is a type of enamel defect affecting, as the name suggests, the first molars and incisors in the permanent dentition. [1] MIH is considered a worldwide problem with a global prevalence of 12.9% and is usually identified in children under 10 years old. [2]
