Anterior Teeth Indentification Flashcards
Anterior teeth are composed of how many developmental lobes?
Four
How many developmental lobes are in the labial of anterior teeth?
3
Name the three labial developmental lobes.
Mesiolabial lobe
Distolabial lobe
Middle labial lobe
The developmental depressions separating the three labial lobes are
The mesiolabial developmental depression and the distolabial developmental depression
How many developmental lobes are in the lingual of anterior teeth?
1
The biting surface or edge of the anterior teeth is called the
Incisal edge, incisal ridge or incisal surface
What are succedaneous teeth?
The permanent teeth that come to replace primary teeth.
The succedaneous anterior teeth replace
The primary teeth of the same type
How many of the anterior teeth are succedaneous?
All of them
How many permanent anterior teeth are in the mouth?
12
How many permanent incisors are in the mouth?
8
How many permanent central incisors are in the mouth?
4
How many permanent lateral incisors are in the mouth?
4
How many permanent canines are in the mouth?
4
What are the three types of permanent anterior teeth?
Central incisors, lateral incisors and canines
If viewed from the proximal, the shape of all anterior teeth would be what shape?
Triangular
If the shape of all anteriors from a proximal view would be triangular, where would be the base of the triangle and where would be the apex of the triangle.
At the cervical third/cervix (base)
At the incisal third/incisal ridge (apex)
The incisors function in chewing is
Biting and cutting
The canines’ function in chewing is
Tearing, ripping, cutting
From the labial view (mesial and distal), the height of contour of all anterior teeth is
Incisal third
If viewed proximally or labial-lingually, the height of contour of all anterior teeth is
Cervical third
What is a contact area?
The area where crowns of adjacent teeth in the same arch physically touch each other
In comparison to posterior teeth, is the contact area between anterior teeth larger or smaller?
Smaller
What is the CEJ?
Cementoenamal junction
