Molars

max molar

6 molar - 3 in reach quadrant

Maxillary molar have 3 roots

• 2 b

• 1 p

Lobes

exception of the third. Max have at least 4 cusp

max. 1st molar = 5 cusp

max 2nd molar = 4 cusp

cusp = lobes

mandibular 2nd molar antagonist

Max 1 + 2nd molar

mandibular 2nd molar features

4 cusp

2 root

2 pulp

mesial cusp are larger

tooth is small than mand. 1st molar

Max + Mand 3rd molar

Show developmental variation

no standard structural

teeth are likely to be anomalies

roots are often fused or malformed

Max 3rd molar number

R.1

Max 3rd molar eruption

17-21

Max 3rd molar antagonist

Mand 3 molar

Max 3rd molar features

crown often heart shape

3 fused root

developed from 4 lobes

may resemble 1st or 2nd molar if developed properly

Mand 3rd molar number

R. 32

L.17

Mand 3rd molar eruption

17-21

Mand 3rd molar antagonist

Max 2nd + 3rd molar

Mand 3rd molar feature

crown do not conform to normal size

root often fused

if well developed looks like 1 or 2nd molar

developed from 4 lobes

often atypical
