DAM Lecture 1 - Tooth ID systems and basic tooth structures

Dentition and types and amount

All the teeth together in the mouth

- primary/ decidious: baby teeth (20)

- secondary: permenant (32)

Incisors

- Central and lateral

- Cutting and shearing food

Canines

longest roots

Premolars

- first and second

- tearing food (like canines and molars)

Molars

- first, second, third

- fulcrum, closest to TMJ

Universal Secondary teeth

Upper: (1-> 16)

Lower: (32->17)

NOTES:

- canines: 6, 11 & 22, 27

- front: 8, 9 & 24, 25

Universal Primary teeth

Upper: (A-J)

Lower: (T-K)

NOTES:

- canines: C, H & M, R

- front: E, F & O, P

Dental formula decidious teeth and what everything stands for

*note: this formula only represents one side (L or R) of mouth

I 2/2 C 1/1 M 2/2

I= incisor (2 top 2 bottom)

C= canine (1 top 1 bottom)

M= molar (2 top 2 bottom)

*no premolars for primary

Dental formula secondary teeth and what everything stands for

*note: this formula only represents one side (L or R) of mouth

I 2/2 C 1/1 PM 2/2 M 3/3

I= incisor (2 top 2 bottom)

C= canine (1 top 1 bottom)

PM= pre molar (2 top 2 bottom)

M= molar (3 top 3 bottom)

Anatomical vs Clinical (root and crown)

Anatomical: expected root and crown

Clinical: crown is whatever is exposed, root is what is not exposed
