Question 1

How do you identify a permanent maxillary central incisor?

(and if it’s from the R/L)

Answer 1

• Large wedge-shaped tooth with 1 root

-The mesial surface is straighter than the distal surface

Question 2

How do you identify a permanent maxillary lateral incisor?

(and if its R/L)

Answer 2

-Shorter, narrower and rounder than central max
-More pronounced cingulum
-Foremen caecum incisvium (palatal pit)

-Root curves distally (e.g. if it curves to the right then it’s on the left hand side of the patients mouth)

Question 3

How do you identify a permanent mandibular central incisor?

(and if it’s R/L)

Answer 3

-Smallest of any tooth
-Least developed cingulum

-Root curves distally
-Bilaterally Symmetric crown

Question 4

How do you identify a permanent mandibular lateral incisor?

(and if it’s R/L)

Answer 4

-Slightly larger than central
-Crown twisted distally on root in the lingual direction

-Mesial edge is slightly longer
-Crown twisted distally

Question 5

How do you identify a permanent maxillary canine?

Answer 5

• 1 root (max)
  -Distal bulge than the mandibular

-Distal slope of cusp tip is longer
-Distally inclined root

Question 6

How do you identify a permanent mandibular canine?

Answer 6

-May have 2 roots (mand)
-Distally tilted on root

-Distal side is convex (curved)

Question 7

How do you identify a permanent maxillary 1st pre-molar?

(and if it’s R/L)

Answer 7

• 1/2 roots (Max)
  -Occlusally wider buccally

Question 8

How do you identify a permanent mandibular 1st premolar?

(and if it’s R/L)

Answer 8

• 1 root (Mand)
  -2 cusps joined by a central ridge (sloth eyes)

-Distal slope of buccal cusp is longer

Question 9

How do you identify a permanent maxillary 2nd pre-molar?

(and if it’s R/L)

Answer 9

-1/2 roots (Max)

(and if it’s R/L)

Answer 10

-1 root (mand)
-3 cusps (rose)

-Mesial marginal ridge is higher than the distal

Question 11

How do you identify a permanent maxillary 1st molar?

(and if it’s R/L)

Answer 11

-3 roots (max) divergent (6)
-4 main cusps and a cusp of carabelli may be present

-Mesiobuccal cusp is the highest

Question 12

How do you identify a permanent maxillary 2nd molar?

(and if it’s R/L)

Answer 12

-3 roots (max) less divergent (7)
-Smaller than 6
-Oblique ridge

-Very small distopalatal cusp
-Distally inclined roots
