  2. Human tooth - Wikipedia

    en.wikipedia.org/wiki/Human_tooth

    Dental anatomy is dedicated to the study of tooth structure. The development, appearance, and classification of teeth fall within its field of study, though dental occlusion, or contact between teeth, does not. Dental anatomy is also a taxonomic science as it is concerned with the naming of teeth and their structures. This information serves a ...

  3. Cementoenamel junction - Wikipedia

    en.wikipedia.org/wiki/Cementoenamel_junction

    In about 60–65% of teeth, the cementum overlaps the enamel at the CEJ, while in about 30% of teeth, the cementum and enamel abut each other with no overlap. In only 5–10% of teeth, there is a space between the enamel and the cementum at which the underlying dentin is exposed. [3]

  4. Universal Numbering System - Wikipedia

    en.wikipedia.org/wiki/Universal_Numbering_System

    The uppercase letters A through T are used for primary teeth and the numbers 1 - 32 are used for permanent teeth. The tooth designated "1" is the maxillary right third molar ("wisdom tooth") and the count continues along the upper teeth to the left side. Then the count begins at the mandibular left third molar, designated number 17, and ...

  5. Periodontal fiber - Wikipedia

    en.wikipedia.org/wiki/Periodontal_fiber

    The main principal fiber group is the alveolodental ligament, which consists of five fiber subgroups: alveolar crest, horizontal, oblique, apical, and interradicular on multirooted teeth. Principal fibers other than the alveolodental ligament are the transseptal fibers.

  6. Molar (tooth) - Wikipedia

    en.wikipedia.org/wiki/Molar_(tooth)

    The molars or molar teeth are large, flat teeth at the back of the mouth. They are more developed in mammals. They are used primarily to grind food during chewing. The name molar derives from Latin, molaris dens, meaning "millstone tooth", from mola, millstone and dens, tooth. Molars show a great deal of diversity in size and shape across the ...

  7. Periodontium - Wikipedia

    en.wikipedia.org/wiki/Periodontium

    Each of these components is distinct in location, architecture, and biochemical properties, which adapt during the life of the structure. For example, as teeth respond to forces or migrate medially, bone resorbs on the pressure side and is added on the tension side. Cementum similarly adapts to wear on the occlusal surfaces of the teeth by ...

  9. 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.
