Orofacial Anatomy

  1. True or False

    A healthy tooth will exhibit a slight mobility when pressure is applied?
    True
  2. NUMBER OF PULP CANALS

    Maxillary first premolar
    Two Canals
  3. NUMBER OF PULP CANALS

    Mandibular first premolar
    One canal
  4. NUMBER OF PULP CANALS

    Mandibular third molar
    Unpredictable
  5. NUMBER OF PULP CANALS

    Maxillary first molar
    Three Canals
  6. Which incisor is most likely to have two pulp canals?
    Mandibular lateral
  7. Canines usually have how many root canals?
    One
  8. What does Anoxia mean?
    lack of oxygen
  9. TRUE OF FALSE

    If there is an infection within a tooth, harmful gases can cause the root canal to expand.
    • False
    • The gases expand but the root canal remains the same size.
  10. What does furcation mean?
    • The region of division of tooth root.
    • It is a bifurcation if there are two roots or a trifurcation if there are three roots.
  11. TRUE OR FALSE

    Furcations are closer to the CEJ on mandibular molars than on maxillary molars.
    TRUE
  12. TRUE OR FALSE

    All anterior teeth have a ridge-like biting edge.
    • FALSE
    • Incisors do have an incical ridge, but canines have a cone shaped cusp point.
  13. TRUE OR FALSE

    A central incisor is better able to resist displacement from forces than a canine.
    • False
    • Canines have longer roots than central incisors.
  14. TRUE OR FALSE

    Mandibular incisors show a slight attrition (or wearing down) on the labioincisal surface.
    TRUE
  15. TRUE OR FALSE

    Tertiary anatomy refers to the numerous grooves, pits, and lines that third molars often have.
    TRUE
  16. TRUE OR FALSE

    Because of their longer roots, maxillary lateral incisors have a greater crown-to-root ratio than maxillary centrals.
    • FASLE
    • They have a lesser crown to root ratio.
  17. TRUE OR FALSE

    The more posterior a molar is located, the closer together the roots will be.
    TRUE
  18. TRUE OR FALSE

    Maxillary centrals and laterals are wider labiolingually than mesiodistally.
    • Fasle
    • Mandibular incisors are wider labiolingually.
  19. TRUE OR FALSE

    The Mandibular Lateral is most likely to have a proximal groove in its root.
    TRUE
  20. When does the mandibular lateral incisor erupt?
    7-8 years
