This flashcard set is designed for university-level medical students focusing on dental anatomy. It covers key aspects of primary and permanent teeth, including eruption sequences, anatomical features like the primate and leeway spaces, and the functions of primary dentition. The flashcards also address the development timeline of primary teeth, from calcification in utero to crown completion. Dental professionals and students will find this set particularly useful for understanding the growth and structural nuances of teeth, aiding in both academic studies and clinical practice.

Flashcards

Primary denttion is also known as?

  • Primary
  • Deciduous
  • Milk teeth
  • Baby teeth

What is the function of primary dentition?

  • Masication
  • Support for lips and cheeks
  • Speech
  • Maintain arch space for secondary teeth

When does calcification of primary teeth begin?

4-6 months in utero

When is the crown complete on primary teeth?

Within the 1st year after birth

What is a general rule of thumb for determining if a child has the proper amount of teeth for their age?

Take the child's age in months and subtract 4 this will tell you how many teeth the child should have at that age. (give or take 1-2 teeth)

This is the combined mesial/distal arch space of primary canines and molars that is greater then the permanent canines and premolar space. It is a difference in arch space.

Leeway space

This is the spaces that occur on the mesial and distal of primary teeth that allow for adult teeth to erupt.

Primate space

What is the order of permanent eruption?

  1. 1st Molars
  2. Mandibular Central Incisors
  3. Other incisors
  4. Mandibular Canine
  5. Premolars **Maxillary 2nd before Mandibular 2nd only maxillary to proceed mandibular)
  6. Maxillary Canines
  7. 2nd Molars
  8. 3rd Molars

True/False:

  • Primary crowns are tapered at the CEJ.
  • The enamel is less mineralized
  • They have smaller root canals
  • They have more anomalies than the permanent
  • The 2nd molars are larger than the 1st

  • True
  • True
  • False: larger root canals
  • False: less anomalies
  • True

True/False:

When a primary incisor erupts there are no mamelons.

True
