  2. The smooth elevated area between the eyebrows is the
  3. The prominence of the forehead
    the frontal eminence
  4. thin membrane lining the inside of the eyelids and the front of the eyeball
  5. The nares are separated by the midline
    nasal septum
  6. The nares are bounded laterally on each side by a winglike cartilaginous structure
    the ala
  7. One of the muscles in the upper cheek is the
    masseter muscle
  8. The lips are outlined from the surrounding skin by the transition of
    ˜mucocutaneous junction
  9. The upper and lower lips meet at each corner of the mouth or
    labial commissure
  10. An inflammatory lesion at the labial commissure
    Angular cheilitis
  11. A tissue-covered elevation of bone on the posterior aspects of the maxilla just posterior to the most distal maxillary molar
    maxillary tuberosity
  12. A similar feature on the mandible just posterior to the most distal mandibular molar is a dense pad of tissue
    the retromolar pad
  13. The __________  is the prominence of the chin
    mental protuberance
  14. Between the lower lip and the chin
    The labiomental groove
  15. Sublingual fold
    • A ridge of tissue also exists on each side of the floor of the mouth
    • Together these folds are arranged in a “V”-shaped configuration from the lingual frenum to the base of the tongue
  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
  18. Primary dentition period occurs between
    ˜between approximately 6 months and 6 years of age.
  19. The mixed dentition period occurs between
    6 and 12 years of age
  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
    cementoenamel junction (CEJ)
  26. All roots of the teeth are widest at the
  27. Roots have more bulk on the ______ surface than the ______ surface
    • facial
    • lingual
  28. Many surfaces of the roots have
    root concavities
  29. Root concavities occur on the
    • Mesial/Distal of anterior and posteriors
    • Buccal/Lingual surface of molars
  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
  31. A line angle is formed by
    the lines created at the junction of two crown surfaces
  32. How many line angles does the posterior teeth have
    8 line angles
  33. How many line angles does the anterior teeth have
    6 line angles
  34. A point angle is
    The junction of three surfaces of the crown
  35. Each tooth has how many point angles
  36. The incisors function as instruments for
    biting and cutting food
  37. The canines function as instruments for
    pierce or tear food
  38. The premolars function as instruments for
    • assisting the canines in piercing and tearing food
    • assisting the molars in grinding food
  39. The molars function as instruments for
    grinding food during mastication
