traits of all incisors
mamelon, developmental depression, distal slopes more rounded, roots wider faciolingually, roots longer than crowns, roots curve slightly distally, CEJ curves more on mesial, triangular shape from proximal
Maxillary Central Incisor numbers
Maxillary Central Incisor eruption ages
average 7-8
Maxillary Central Incisor size
longest crown of all the teeth; widest of the incisors
Max. Cent. Incisor (labial view)
mamelons, imbrication lines, labial depressions. Almost symmetrical. Contact area Mesial MI line; Distal: incisal 3rd
Max. Cent. Incisor (lingual view)
cingulum off-center distal; chance of lingual pit
Max. Cent. Incisor (proximal view)
CEJ curvature more prounounced on mesial than any other tooth
Max. Cent. Incisor (incisal view)
"distolingual twist"
Max. Cent. Incisor (root)
straight, conical; up to 1 1/2x longer than crown; apex blunt; 3 pulp horns; large pulp chamber; sensitive; accidents can damage
Max. Cent. Incisor (anomolies)
supernuerary (mesiodens); diastema (middle of 8&9); avulsion (lost tooth); attrition (bruxing or loss of tooth structure)
Max. Lateral Incisor numbers
Max. Lateral Incisor eruption
Max. Lateral Incisor
extreme variability in anatomy with peg laterals (congenital); 2nd most frequently missing (3rd molars are most)
Max. Lateral Incisor
often confused with small mand. canine
Max. Lateral Incisor (facial view)
imbrication lines and depressons NOT as pronounced; m & d sides more rounded than central, with distal more rounded than mesial. Contact area mesial: junction of incisial & middle 3rds. Distal: middle of middle 3rd
Max. Lateral Incisor (lingual view)
LINGUAL PIT; groove, may be "shovel-shaped"
Max. Lateral Incisor (proximal view)
CEJ curvature greater on Mesial
Max. Lateral Incisor (incisal view)
cingulum centered
Max. Lateral Incisor (root)
1 1/2x longer than crown (longer than centrals), conical, but narrower, development depresson on mesial surface, single root canal; NO pulp horns
Max. Lateral Incisor (anomolies)
microdontia (peg lateral); anodontia (congenitally missing), dilacerations, curved root
Mandibular Incisors (general)
smallest perm. teeth, laterals larger, developmental grooves on root. Root is hourglass shape. Lingual fairly smooth. Wider F-D. Wear (attrition) makes incisal edge straight. single root canal, 3 pulp horns.
Mand. Incisor (anomolies)
bifurcated or accessory root, attrition, calculus
Mand. Central Incisor number
Mand. Central Incisor eruption
Mand. Central Incisor 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)
incisal edge pints more lingual. very wide f-l
Mand. Central Incisor (incisal)
cingulum is in center
Mand. Lateral Incisor number
Mand. Lateral Incisor eruption
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
Max. Canines general
longest roots; sharp pointed cusp; lingual vertical ridge divides lingual fossa; most stable; form corners of arch; alveolar bone forms canine eminence; more yellow; root concavities on both proximal surfaces
Max. Canines eruption
Max. Canines number
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)
contact areas: mesial: junction of incisial and middle 3rd, Distal: middle of middle 3rd. Crown and root not as wide. Shortest distance from MI line angle to cusp tip. pentagonal.
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.
Max. Canines (proximal)
Wider from facial to lingual than other anteriors. Develop. depression deeper on distal.
Max. Canines (root)
conical; may curve distal. Large pulp chamber; single root canal; no pulp horns, chamber is rounded.
Mand. Canines eruption
Mand. Canines general
Different from maxillary by: crown is narrower, anatomical crown longer, root is shorter, lingual is smoother (less developed cingulum), cusp tip curved lingual.
Mand. Canines (facial)
distance from MI to cusp is SHORTER than DI to cusp, mesial is straight; distal slightly convex
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
Mand. Canines (incisal)
cingulum offest to distal
Mand. Canines (root)
One pulp chamber and root canal (unless bifurcated). Sometimes 2 RC with only 1 root; root may have slight MESIAL inclination
