Study Notes
Incisors
- Maxillary central incisor: Facial trapezoidal, mesial triangular, incisal triangular.
- Mandibular central incisor: Facial trapezoidal, mesial triangular, incisal ovoid.
- Maxillary lateral incisor: Facial trapezoidal, mesial triangular, incisal triangular.
- Mandibular lateral incisor: Facial rectangular, mesial triangular, incisal ovoid; cingulum offset from center; distolingual twist from incisal view; least square disto-incisal line angle.
Canines
- Maxillary canine: Facial pentagonal, mesial triangular, incisal rhomboidal, large cingulum, 2 deep fossae.
- Mandibular canine: Facial pentagonal, mesial triangular, incisal rhomboidal, narrower than maxillary, 2 fossa, cingulum may be off center.
Maxillary Premolars
- First premolar: Buccal trapezoid, mesial trapezoid, occlusal hexagonal, buccal cusp larger than lingual; long, defined central groove; mesial-marginal ridge passes marginal ridge; lingual cusp tilted towards mesial.
- Second premolar: Buccal trapezoid, mesial trapezoid, occlusal ovoid, cusp shorter than 1st; mesial marginal groove does not cross marginal ridge; central groove shorter than 1st.
Mandibular Premolars
- First premolar: Buccal trapezoid, mesial rhomboidal, occlusal diamond, 2 cusps, buccal cusps visible, 1 root, transverse ridge/ML groove.
- Second premolar: Buccal trapezoid, mesial rhomboidal, occlusal square, 2-3 cusps, no transverse ridge/ML groove, buccal cusps not visible from lingual.
Maxillary Molars
- First molar: Widest, buccal trapezoidal, occlusal rhomboidal, 3 roots (curved distally + flared), cusp of carabelli (lingual aspect).
- Second molar: Buccal trapezoidal, occlusal rhomboidal, 3 roots, buccal cervical ridge more prominent than 1st, more supplementary roots than 1st.
- Third molar: Buccal trapezoidal, occlusal heart-shaped, root trunk height longest + tallest, roots usually fused (buccal aspect), lingual lobe largest, many accidental grooves (unless worn).
Mandibular Molars
- First molar: Widest, buccal trapezoidal, occlusal hexagonal, 2 roots widely separated, nearly vertical, distal cusp = 5th cusp, narrow cervical dimension.
- Second molar: Buccal trapezoidal, occlusal rectangular, mesial rhomboidal, roots shorter but trunk height longer, cusps nearly equal.
- Third molar: Smallest and varies the most, buccal trapezoid, occlusal ovoid, mesial rhomboid, roots fused or separate; similar to second molar; cervical dim least narrow.
Maxillary Premolars
- First Premolar: Buccal cusp slightly longer; mesial marginal developmental groove; crosses marginal ridges; mesial developmental depression; 2 roots (buccal + lingual); lingual cusp tilted toward mesial; H-shaped grooves.
- Second Premolar: Single root; buccal lingual cusps equal; marginal ridge lower on distal.
Mandibular Premolars
- First premolar: Large buccal cusp; small lingual cusp, more pointed; mesiolingual developmental groove; prominent buccal triangular ridges.
- Second premolar: Larger than 1st; only premolar with 3 cusps (ML>DL); could have central pit; Y-shaped central groove.
Maxillary Molars
- First molar: Largest crown in dentition; buccal = trapezoidal; occlusal = rhomboidal; three roots, curved distally + flared; cusp of carabelli (lingual aspect); large buccal cervical ridge more prominent than first molar; supplementary roots more prevalent than first molar.
- Second molar: Buccal-trapezoidal; Occlusal = rhomboidal; 3 roots; buccal cervical ridge more prominent than 1st; more supplementary roots than 1st.
- Third molar: Buccal-trapezoidal; occlusal = heart-shaped; root trunk height longest + tallest; roots usually fused; lingual lobe largest; many accidental grooves (unless worn).
Mandibular Molars
- First molar: Widest; buccal = trapezoidal; occlusal = hexagonal; 2 roots widely separated, nearly vertical; distal cusp = 5th cusp; narrow cervical dimension.
- Second molar: Buccal = trapezoidal; occlusal = rectangular; mesial = rhomboidal; roots shorter but trunk height longer; cusps nearly equal
- Third molar: Smallest + varies the most; buccal = trapezoidal; occlusal = ovoid; mesial = rhomboid; roots fused or separate; similar to second molar; cervical dim least narrow.
