Question 1

Upper central incisor

Answer 1

• Larger than upper lateral incisor
• Mesioincisal angle is sharp and the distoincisal angle is rounded
• Incisal edge is straight
• Cingulum is centralised
• Conical and round root

Question 2

Upper lateral incisor

Answer 2

• Incisal edge is sloping distally
• Cingulum is twisted distally
• Root apex curved distally
• Presence of palatal pit
• Both incisal angles are rounded

Question 3

Lower central incisor

Answer 3

• Most symmetrical teeth
• Smallest teeth in the oral cavity
• Lingually inclined
• Incisal edge and cingulum – centralised
• Mesioincisal and distoincisal angles are sharp

Question 4

Lower lateral incisor

Answer 4

• Larger than lower central incisor
• Has sharp mesioincisal angle and round distoincisal angle
• Incisal edge sloping distally
• Cingulum twisted distally
• Root apex curved distally

Question 5

Upper Canine

Answer 5

• The Crown is shorter and broader
• Lingual ridge is very prominent
• The lingual ridge runs from the cusp tip to the cingulum – divides lingual
  fossae into two
• Longest root in the oral cavity
• Cusp tip is pointed
• The mesial cusp slope is shorter than the distal cusp slope
• Root is curved distally

Question 6

Lower canine

Answer 6

Crown is longer and narrower
- Lingual ridge is present only on the incisal third
- Crown is lingually inclined
- Cusp tip is less pointed than the upper canine
- Mesial cusp slope is shorter than distal cusp slope
- Root is shorter than upper canine
- Root is curved distally
