Permanent Maxillary And Mandibular Canines Question And Answers

The Permanent Canines Canines Maxillary And Mandibular

Question 1. Describe in detail about permanent maxillary canine.
Answer:

Labial aspect:

• The cervical line is convex labially
• The mesial outline is convex while the distal outline is concave.
• The distal contact area is at the center of the middle third of the crown.
• The cusp tip is on a line with the center of the root.

• The cusp has a shorter mesial slope and a distinct distal slope.
• The labial surface is smooth.
• There are shallow depressions dividing the labial surfaces into 3 labial lobes.
• The middle lobe is well-developed.
• The root appeas slender with a bluntly pointed apex.
• The labial surface of the root is smooth and convex at all points.

Lingual aspect:

• The cingulum is large and pointed like a small cusp.
• Definite ridges are found below the cingulum and between marginal ridges.
• Shallow concavities called mesial and distal lingual fossae are present between the ridge and the marginal ridges.
• The lingual portion of the root is narrower.
• The lingual ridge of the root is smooth and convex at all points from the cervical line to the apical end.

Mesial aspect:

• The outline is wedge-shaped.
• The labial and lingual outline are convex.
• The cervical line curves towards the cusp.
• The root outline is conical, with a tapered or bluntly pointed apex.
• The apical third of the root curve labially.
• The mesial surface of the crown is convex at all points except the above contact area.
• The mesial surface of the root appears broad.

Distal aspect:

• The cervical line shows less curvature towards the cusp ridge.
• The distal marginal ridge is irregular.
• The surface is more concave above the contact area.

Incisal aspect:

• The cusp tip is labial to the center of the crown labio-lingually and mesial to the center mesiodistally.
• The ridge of the middle labial lobe is more pronounced labially.
• It attains its greatest convexity at the cervical third.

Chronology:

• The first evidence of calcification – 4-5 months
• Enamel completed -6-7 years
• Eruption -11-12 years
• Root completed – 13-15 years

Measurements:

Question 2. Describe in detail about permanent mandibular canine.
Answer:

Labial aspects:

• The crowns appear longer
• The mesial outline of the crown is nearly straight
• The mesial cusp ridge is shorter.
• The distal contact area is more towards the incisal aspect. The cervical line has a semicircular curvature apically.
• The apical end of the root is more sharply pointed. Root curvature if present, it is in the mesial direction.

Lingual aspect:

• It is flatter, smooth, and regular
• The cingulum is smooth and poorly developed
• The marginal ridges are less distinct.
• The lingual portion of the root is narrower.

Mesial aspect:

• The cusp ridge appears more slender.
• The cusp tip is more nearly centered over the root.
• The cervical line curves towards the incisal portion.
• The developmental depression at the root is deeper and more pronounced.

Distal aspect:

• The distal marginal ridge is irregular
• The developmental depression on the root is more pronounced.
• The surface displays more concave above the contact area.

Incisal aspect:

• The mesial outline is less curved.
• The cusp tip and mesial cusp ridge are more inclined in a lingual direction.
• The distal cusp ridge and the contact area are more distinct.

Question 5. Canines.
Answer:

• They are four in number, and present at the corners of the mouth.
• So, they are referred to as the cornerstone of the dental arch.
• They are the longest & stable teeth in the mouth and the last teeth to be lost.
• It supports incisors & premolars.
• Single, long, strongly developed root help in anchorage.
• The shape of the crown promotes self-cleansing.
• They stabilize replacements of lost teeth.
• Its position in the mouth ensures normal facial expression.
