Cementum enamel Junction
What is the difference between the Anatomical vs Clinical root and crown ?
•Crown and root: Anatomical vs Clinical
•Anatomical crown: covered by enamel
•Anatomical root: covered by cementum
•Clinical crown: visible
•Clinical root: not visible

What are the following ?
Periodontal ligament , Gingiva , Alveolar process , Alveolus
•Alveolar process: bone which supports teeth
•Alveolus: tooth socket
- ligament (PDL): fibers supporting tooth in alveolus
- •Gingiva: soft tissue
- covering alveolar process (“gums”)

What shape do the /maxillary posterior teeth have , proximal view and then facial view ?
What about Mandibular posterior teeth proximal view and facial view?
- Facial = trapezoidal , long edge up
- proximal - trapezoidal , long edge down
- Proximal = rhomboidal
- facial = trapezoidal long edge up
What are the difference between incisal and cervical embrasures from anterior to posterior ?
