    ˜mucocutaneous junction
  9. The upper and lower lips meet at each corner of the mouth or
    labial commissure

  16. The small papilla at the anterior end of each sublingual fold contains openings of the submandibular duct and sublingual duct
    sublingual caruncle
  17. Primary dentition period begins with the eruption of the
    primary mandibular central incisors

  20. The crown of the tooth is made up of
    dentin covered by enamel
  21. The root of the tooth is made up of
    dentin covered by cementum
  22. The bone underlying the maxillary and mandibular arch is called
    Alveolar process
  23. The anatomic crown
    Is the whole crown covered by enamel
  24. The clinical crown
    is that part of the anatomic crown that is visible and not covered by the gingiva
  25. The enamel of the crown and cementum of the root usually meet close to the

  30. Height of contour
    • is the greatest elevation of the tooth either incisocervically or occlusocervically on a specific surface of the crown when viewing its profile from the labial or buccal and the lingual
    • Part of the tooth that it sticking out the farthest
