Permanent Maxillary and Mandibular Canines Lecture

These flashcards cover key vocabulary and concepts from the lecture on permanent maxillary and mandibular canines, including identifying features, developmental timelines, and anatomical aspects.

Permanent Maxillary Canine

The main identifying features include being the third tooth from the midline, the longest root of any tooth in the mouth, and serving a tearing function.

Timeline of Development for Maxillary Canine

First evidence of calcification at 4-5 months, enamel completed at 6-7 years, eruption at 11-12 years, and root completed by 13-15 years.

Labial Aspect of Permanent Maxillary Canine

Crown and root narrow mesiodistally compared to central incisor, with various convex and concave outlines.

Lingual Aspect of Permanent Maxillary Canine

Crown and root are narrower lingually, with a large cingulum and strongly developed marginal ridges.

Mesial Aspect of Permanent Maxillary Canine

The outline is wedge-shaped with a conical root and a bluntly pointed apex.

Incisal Aspect of Permanent Maxillary Canine

Has a greater labiolingual dimension compared to mesiodistal; the ridge of the middle labial lobe is pronounced.

Permanent Mandibular Canine

Identifiable as being the third tooth from the midline and 1-2 mm shorter than maxillary canines, with a similar tearing function.

Timeline of Development for Mandibular Canine

First calcification evidence at 4-5 months, enamel completed at 6-7 years, eruption at 9-10 years, root completed by 12-14 years.

Labial Aspect of Permanent Mandibular Canine

Mesiodistal dimension is less than that of maxillary canines, with a somewhat straight mesial outline and a sharply pointed root.

Lingual Aspect of Permanent Mandibular Canine

Flatter crown surface with less prominent marginal ridges and a smooth, poorly defined cingulum.

Incisal Aspect of Permanent Mandibular Canine

Mesiodistal dimension is less than the labiolingual dimension with an inclined cusp tip.

Canine Anomalies

Includes bifurcated roots and impacted canines, often due to space closure after premolar eruption.

Function of Canines

Primary function includes tearing and holding food.
