  2. Tooth mobility - Wikipedia

    en.wikipedia.org/wiki/Tooth_mobility

    Tooth mobility is the horizontal or vertical displacement of a tooth beyond its normal physiological boundaries [1] around the gingival (gum) area, i.e. the medical term for a loose tooth. Tooth loss implies in loss of several orofacial structures, such as bone tissues, nerves, receptors and muscles and consequently, most orofacial functions ...

  3. Dental avulsion - Wikipedia

    en.wikipedia.org/wiki/Dental_avulsion

    Dental avulsion is the complete displacement of a tooth from its socket in alveolar bone owing to trauma, such as can be caused by a fall, road traffic accident, assault, sports, or occupational injury. [1] [2] Typically, a tooth is held in place by the periodontal ligament, which becomes torn when the tooth is knocked out. [3]

  4. Dental subluxation - Wikipedia

    en.wikipedia.org/wiki/Dental_subluxation

    It is most commonly seen in school children. Dental subluxation is one of the most common traumatic injuries in primary dentition. Maxillary central incisors are the most commonly affected teeth. [10] [11] Some studies have proposed that the resilience nature of periodontium favours dislocation than fracture of the tooth itself. [12]

  5. Dental anatomy - Wikipedia

    en.wikipedia.org/wiki/Dental_anatomy

    Diagram of tooth anatomy. Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.)

  6. Human tooth - Wikipedia

    en.wikipedia.org/wiki/Human_tooth

    Bottom teeth of a seven-year-old, showing primary teeth (left), a lost primary tooth (middle), and a permanent tooth (right) Tooth eruption in humans is a process in tooth development in which the teeth enter the mouth and become visible. Current research indicates that the periodontal ligaments play an important role in tooth eruption.

  7. Dental intrusion - Wikipedia

    en.wikipedia.org/wiki/Dental_intrusion

    Dental intrusion is an apical displacement of the tooth into the alveolar bone.This injury is accompanied by extensive damage to periodontal ligament, cementum, disruption of the neurovascular supply to the pulp, and communication or fracture of the alveolar socket.

  8. Taurodontism - Wikipedia

    en.wikipedia.org/wiki/Taurodontism

    Taurodontism is defined as the enlargement of pulp chambers with the furcation area being displaced toward the apex of the root of a tooth. It cannot be diagnosed clinically and requires radiographic visualization since the crown of a taurodontic tooth appears normal and its distinguishing features are present below the alveolar margin.

  9. Maxillary central incisor - Wikipedia

    en.wikipedia.org/wiki/Maxillary_central_incisor

    There are some minor differences between the deciduous maxillary central incisor and that of the permanent maxillary central incisor. The deciduous tooth appears in the mouth at 8–12 months of age and shed at 6–7 years, and is replaced by the permanent tooth around 7–8 years of age. The permanent tooth is larger and is longer than it is ...
