Tooth Morphology

Question 1

During lateral movement of the jaw, this tooth acts as a guidepost with its antagonist

Answer 1

Upper Canine

Question 2

In this tooth the distal fossa is generally larger than the mesial fossa

Answer 2

Lower second premolar

Question 3

This tooth has a pit on its buccal surface whihc is at increased risk of caries

Answer 3

Lower First Premolar

Question 4

This too has the mesial surface more deeply gooved than the distal and shows a concavity in the cervical region

Answer 4

Upper First Premolar

Question 5

Crown set an angle to root, producing convex labial profile drom cusp to apex. Often has enamel exteding furhter apically on labial side than on lingual side

Answer 5

Lower Canine

Question 6

In this tooth, the lingual cusp is displaced distally. A small groove often runs from the mesial pit on to the mesiolingal surface

Answer 6

Lower First Premolar

Question 7

The crown is by far the largest of the 4 incisors. Being almost as wide as it is long

Answer 7

Upper Central

Question 8

Usually, this tooth only has four cusps of similar size, The occlusal surface is almost square

Answer 8

Lower Second Permanent Molar

Question 9

This tooth is diamond shaped, with the longer diagonal extednign from the mesio-buccal to the disto-palatal cusp

Answer 9

Upper First Permanent Molar

Question 10

The cusps are similar in width and height, due to reduction in size of the buccal cusp

Answer 10

Upper First Premolar

Question 11

The lingual surface has two pronounced marginal ridges. Sometimes, where the ridges meet at the cervix, they enclose a depression or fossa

Answer 11

Upper Lateral Incisor

Question 12

Looking at the crown from the mesial and distal aspects, it appears as wedged shaped and leans lingually. There are faint marginal ridges and a small cingulum

Answer 12

Lower Lateral Incisor

Question 13

The disto-palatal cusp is greatly reduced, and may be asbent. Thus making the shape of the crown more triangular

Answer 13

Upper Second Permanent Molar
