|
|
Mandibular Incisors (general)

|
1st perm. tooth to erupt AFTER 1st molars; smallest; single antagonist; bilaterally symmetrical
|
|
Mand. Central Incisor (facial)
|
M&D nearly straight; root is thin, may curve distally; contact areas m&d at incisal 3rd.
|
|
Mand. Central Incisor (lingual)
|
no pits; surface is narrower than facial
|
|
Mand. Central Incisor (proximal)
|

#23,26
|
|
Mand. Lateral Incisor eruption
|
7-8
|
|
Mand. Lateral Incisor general
|
larger in all dimensions including root length than mand. centrals; 2nd smallest perm. tooth; cingulum shift distally; surfaces of crown more rounded.
|
|
Mand. Lateral Incisor (facial)
|
smooth facial surface, labial developmental depressons more pronounced; distal more curved. root long and thin; may curve distal. Line angle: MI 90 degrees; DI more rounded. Contact area Mesial: MI line angle; Distal: toward middle (still in incisal 3rd)
|
|
Mand. Lateral Incisor (lingual)
|
all structures more prononuced than mand. centrals
|
|
Mand. Lateral Incisor (proximal)
|
same general shape as mand. centrals; incisal edge curves lingually. Root wider and has concavities, which are more pronounced on distal
|
|
Mand. Lateral Incisor (incisal)
|
cingulum shifted distal; DI line angle visibly more lingual than MI angle
|
|

#6,11
|
|
Max. Canines general
|
Middle lobe forms cusp; largest cingulum of any anterior. If erupt incorrectly, can shift midline. Can be impacted sideways.
|
|
Max. Canines (facial)

|
|
Max. Canines (lingual)
|
lingual convergance because crown and root are narrower. large cingulum offset to distal. Vertical line ridge separates fossa. May have lingual pit.

|
|
Mand. Canines (lingual)
|
similar to maxillary, EXCEPT structures aren't as noticable.
|
|
Mand. Canines (proximal)
|
cusp tip more lingual, CEJ curves more on mesial, root is wide facial-lingual, developmental depression (root concavity) more pronounced on distal; MOST likely to have bifurcated root on apical 3rd
