[peg lateral]

Abnormally small maxillary lateral incisors

Question 20

Talon Cusp

Answer 20

Claw shaped extra cusp on lingual
Risk of pulp horn exposure
(maxillary incisors)

Screwdriver shaped crown
Due to congenital syphilis [treponema pallidum]
(maxillary incisors)

Question 22

Mesiolabial
Middle labial
Distolabial
Lingual

Question 24

Cingulum

Answer 24

Raised, rounded area on cervical 3rd of lingual

Lingual mesial/distal border ridges

Question 26

Fossa(e)

Answer 26

Shallow, wide lingual depression

Question 27

Developmental Groove

Answer 27

Sharp,deep,V-shaped lingual linear depression; marks junction of developmental lobes

Question 28

Supplemental Groove

Answer 28

Shallower, irregular branch from developmental groove

Question 29

Features: Central Maxillary Incisors

Answer 29

Largest, widest crown, most prominent, Imbrication lines

Round root, No concavities

Question 30

Distinguish R from L: Incisors

Answer 30

mesioincisal angle is sharp, distoincisal is more round.

CEJ greater curvature on mesial

Question 31

Features: Maxillary Lateral Incisors

Answer 31

Greatest degree of crown variation, root sharp/curves distal, Distolingual marginal groove-makes tooth more prone to perio disease, Lingual Pit more common

Question 32

Linguogingival groove

Answer 32

Separates cingulum from lingual fossae - Max lateral incisors

Anadontia

Answer 33

Absence of a single tooth or multiple teeth, congenitally missing
Most common in Max Lateral Incisors

Question 34

Distolingual marginal groove

Answer 34

Extends to root - makes periodontial disease common

Max Lat Incisors

Question 35

One antagonists, smallest/simplest, root concavities, centered cingulum
Mesial/Distal contact: incisal 3rd

Question 36

Features: mandibular Lateral Incisors

Answer 36

Mesial/Distal contact: incisal 3rd

Appears twisted distally, bigger than centrals. Root concavities
