Permanent Anterior Teeth

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 (narrow) and round root

Question 2

Upper lateral Incisor

Answer 2

• Incisal edge is sloping distally (from distal down to mesial)
• 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 are 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
• Lingual Ridge runs from 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
