  2. Enamel hypocalcification - Wikipedia

    en.wikipedia.org/wiki/Enamel_hypocalcification

    Enamel hypocalcification is a defect of tooth enamel in which normal amounts of enamel are produced but are hypomineralized. [ 1 ] [ 2 ] In this defect the enamel is softer than normal. Some areas in enamel are hypocalcified: enamel spindles, enamel tufts, and enamel lamellae.

  3. Enamel hypoplasia - Wikipedia

    en.wikipedia.org/wiki/Enamel_hypoplasia

    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 ...

  4. Tooth enamel - Wikipedia

    en.wikipedia.org/wiki/Tooth_enamel

    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]

  5. Enamel organ - Wikipedia

    en.wikipedia.org/wiki/Enamel_organ

    Tooth development begins at week 6 in utero, in the oral epithelium. The process is divided into three stages: Initiation; Morphogenesis and; Histogenesis [2]; At the end of week 7 i.u., localised proliferations of cells in the dental laminae form round and oval swellings known as tooth buds, which will eventually develop into mesenchymal cells and surround the enamel organ.

  6. Linear enamel hypoplasia - Wikipedia

    en.wikipedia.org/wiki/Linear_enamel_hypoplasia

    ] It is the most common type of enamel hypoplasia reported in clinical and archaeological samples, with other types including plane-form enamel hypoplasia and pitting enamel hypoplasia. [12] Linear enamel hypoplasia can be caused by a variety of factors, from genetic conditions to malnutrition and illnesses during childhood.

  7. Dental fluorosis - Wikipedia

    en.wikipedia.org/wiki/Dental_fluorosis

    Dental fluorosis is a common [2] disorder, characterized by hypocalcification of tooth enamel caused by ingestion of excessive fluoride during enamel formation. [ 3 ] [ needs update ] Dental fluorosis appears as a range of visual changes in enamel [ 4 ] causing degrees of intrinsic tooth discoloration , and, in some cases, physical damage to ...

  9. Tooth discoloration - Wikipedia

    en.wikipedia.org/wiki/Tooth_discoloration

    Enamel hypoplasia and enamel hypocalcification are examples of defective enamel that potentially gives a discolored appearance to the tooth. Teeth affected in this way are also usually more susceptible to further staining acquired throughout life. Amelogenesis imperfecta is a rare condition that affects the formation of enamel (amelogenesis ...
