  2. Tooth enamel - Wikipedia

    en.wikipedia.org/wiki/Tooth_enamel

    Parts of a tooth, including the enamel (cross section). Tooth enamel is one of the four major tissues that make up the tooth in humans and many animals, including some species of fish. It makes up the normally visible part of the tooth, covering the crown. The other major tissues are dentin, cementum, and dental pulp.

  3. Molybdenum - Wikipedia

    en.wikipedia.org/wiki/Molybdenum

    Molybdenum is also present within human tooth enamel and may help prevent its decay. [96] Acute toxicity has not been seen in humans, and the toxicity depends strongly on the chemical state. Studies on rats show a median lethal dose (LD 50) as low as 180 mg/kg for some Mo compounds. [97]

  4. Enamel organ - Wikipedia

    en.wikipedia.org/wiki/Enamel_organ

    The enamel organ, also known as the dental organ, is a cellular aggregation seen in a developing tooth and it lies above the dental papilla. [1] The enamel organ which is differentiated from the primitive oral epithelium lining the stomodeum. The enamel organ is responsible for the formation of enamel, initiation of dentine formation ...

  5. Human tooth development - Wikipedia

    en.wikipedia.org/wiki/Human_tooth_development

    Human tooth development. Tooth development or odontogenesis is the complex process by which teeth form from embryonic cells, grow, and erupt into the mouth. For human teeth to have a healthy oral environment, all parts of the tooth must develop during appropriate stages of fetal development.

  6. Molybdenum in biology - Wikipedia

    en.wikipedia.org/wiki/Molybdenum_in_biology

    The molybdenum cofactor (pictured) is composed of a molybdenum-free organic complex called molybdopterin, which has bound an oxidized molybdenum (VI) atom through adjacent sulfur (or occasionally selenium) atoms. Except for the ancient nitrogenases, all known Mo-using enzymes use this cofactor. Molybdate is transported in the body as MoO 42−.

  7. Enamel hypoplasia - Wikipedia

    en.wikipedia.org/wiki/Enamel_hypoplasia

    Enamel hypoplasia. Enamel hypoplasia is a defect of the teeth in which the enamel is deficient in quantity, [1] caused by defective enamel matrix formation during enamel development, as a result of inherited and acquired systemic condition (s). It can be identified as missing tooth structure and may manifest as pits or grooves in the crown of ...

  8. Remineralisation of teeth - Wikipedia

    en.wikipedia.org/wiki/Remineralisation_of_teeth

    Remineralization is a natural process and does not have to involve fluoride. Tooth remineralization is the natural repair process for non-cavitated tooth lesions, [1][2] in which calcium, phosphate and sometimes fluoride ions are deposited into crystal voids in demineralised enamel. Remineralization can contribute towards restoring strength and ...

  9. Human tooth - Wikipedia

    en.wikipedia.org/wiki/Human_tooth

    Since enamel is semitranslucent, the color of dentin and any restorative dental material underneath the enamel strongly affects the appearance of a tooth. Enamel varies in thickness over the surface of the tooth and is often thickest at the cusp, up to 2.5mm, and thinnest at its border, which is seen clinically as the CEJ. [10]
