Maxillary Second Molar

Mostly 4 cusp
Rhomboidal or heart shaped
DL cusp is absent or very small
3 Roots: 2B (often fused) and 1L
Right/Left: Large ML cusp, small DL cusp, and 3 roots make it easy to distinguish
Maxillary First Molar
5 cusp (cusp of carabelli non-fnxal)
Rhomboidal shape
Seperated by B developmental groove
Cusp size: ML>MB>DB>DL
3 Roots: 2 B and 1L
Right/Left: Large ML cusp, Large L root, and cusp of carabelli
Maxillary Second Premolar
2 Cusp - usually equal in length
Lingual cusp usually tilts toward Mesial
No mesial marginal ridge
Occlusal table is more rounded than first premolar
Root: 1 Root, it may tilt toward distal
Right/Left: Tilt of Lingual cusp
Maxillary First Premolar
2 Cusp - Buccal cusp is longest
Prominent buccal ridge
Both cusp tips are shifted toward the mesial
Right/Left: Mesial developmental depression and ligual cusp is tilted mesially
Roots: 80% of max. first premolars have 2 roots
Maxillary Canine
Distal cusp ridge is longer than mesial cusp ridge
Cusp tip points toward mesial
Maillary Lateral
More narrow M-D
Distal incisal angle is more rounded
Ingual anatomy is more prominent and sometimes a pit
Root is longer than central's root
Maxillary Central
3 developmental ridges
Larger M-D than C-I
Mandibular Central
Smallest tooth in arch
No definite marginal ridges
Very symetrical
Mandibular Lateral
Resembles mandibular central but larger proportions
Incisal edge is "twisted" from the 90 degree angel with a line passing labiolingually through the tooth
Mandibular Canine
More narrow than upper canine
Opposite from upper canine the cups tilts toward distal and has lingual inclination
Has nearly straight mesial line angle
Cingulum is less prominent than maxillary canine
Mandibular First Premolar
"Snake eyes"
Most ill-defined lingual cusp
Distinct feature: ML developmental groove
Large buccal cusp centered over root tip
Right/Left: Distal fossa is more developed and distal surface has a longer radius of curvature
Mandibular Second Premolar
Can have 2 lingual cusp and mesial is larger of the two
With only one ligual cusp, the cusp is tilted toward mesial
Lingual cusp is more prominent than the first premolar's lingual cusp
Y-shape has central pit
U and H-shape have developmental groove that crosses transverse ridge
Mandibular First Molar
5 cusps: 3B 2 L
MB cusp is usually widest and generally largest of all 5 cusp
Pentagonal occlusal outline
2 Root: 1D 1M
Mandibular Second Molar
4 Cusp
2 Roots: Mesial root is thicker than the distal root
Occlusal table: Mesial is more narrow than distal
Maxillary Right First Premolar
Maxillary Right Second Premolar
Mandibular Right First Premolar
Mandibular Right Second Premolar
Maxillary Right First Molar
Maxillary Right Second Molar
Mandibular Right First Molar
Mandibular Right Second Molar
Maxillary Canine
Mandibular Canine
