Permanent Canines Flashcards

Flashcards covering the anatomy, function, and characteristics of permanent canines, including differences between maxillary and mandibular canines.

Permanent Canines

The 'cornerstone' of the dental arches.

Permanent Canines

The longest teeth in the mouth.

Permanent Canines

The only anterior tooth that has a cusp

Canine Eminence

Bone ridge over the labial portion of the roots of both maxillary and mandibular canines.

Functions of Canines

Support the lips and the facial muscles.

Functions of Canines

To cut, pierce, or shear food morsels.

Canine Guidance

A function of canines related to occlusion.

Functions of Canines

Good anchor teeth (abutments) to attach replacements for lost teeth.

Maxillary Canine Cusp Angle

Sharper, more acute

Mandibular Canine Cusp Angle

More blunt

Maxillary Canine Crown Width (Labial View)

Crown wider mesiodistally

Mandibular Canine Crown Width (Labial View)

Crown narrower mesiodistally

Maxillary Canine Mesial Cusp Ridge (Labial View)

Shorter than distal

Mandibular Canine Mesial Cusp Ridge (Labial View)

Mesial cusp ridge almost horizontal

Maxillary Canine Proximal Contacts (Labial)

Mesial, distal proximal contacts more cervical

Mandibular Canine Proximal Contacts (Labial)

Mesial, distal proximal contacts more incisal. Distal contact is more cervical than mesial contact

Maxillary Canine Crown Outline (Labial)

Mesial of crown bulges beyond root outline. Crown outline more convex on distal

Mandibular Canine Crown Outline (Labial)

Mesial crown outline almost continuous with root with little or no bulge. Crown outline more convex on distal, mesial crown outline aligns with root

Maxillary Canine Labial Ridge

More pronounced labial ridge

Mandibular Canine Labial Ridge

Less pronounced labial ridge

Maxillary Canine Root Tip

More pointed root tip

Mandibular Canine Root Tip

More blunt root tip

Maxillary Canine Lingual Anatomy

More prominent anatomy on lingual

Mandibular Canine Lingual Anatomy

Smoother lingual surface

Maxillary Canine Cingulum (Lingual)

Centered

Mandibular Canine Cingulum (Lingual)

Centered or to the distal

Maxillary Canine Mesial Marginal Ridge (Lingual)

Longer than distal marginal ridge

Maxillary Canine Cingulum (Proximal View)

More prominent

Mandibular Canine Cingulum (Proximal View)

Less prominent

Maxillary Canine Cusp Tip (Proximal View)

Labial to root axis line

Mandibular Canine Cusp Tip (Proximal View)

Lingual to root axis line

Maxillary Canine Labial Height of Contour (Proximal)

Less cervical, More pronounced, Closer to cervical line

Mandibular Canine Labial Height of Contour (Proximal)

Less pronounced, almost continuous with root

Maxillary Canine Incisal Wear (Proximal)

More lingual, even in fossae

Mandibular Canine Incisal Wear (Proximal)

More labial

Maxillary Canine Cusp Tip Shape (Proximal)

Appears thicker faciolingually

Mandibular Canine Cusp Tip Shape (Proximal)

Appears less thick faciolingually

Maxillary Canine Cervical Line (Proximal)

Curves more on the mesial than distal surface

Maxillary Canine Root Depression (Proximal)

Distal root depression is more distinct than mesial

Maxillary Canine Crown Outline (Incisal)

More asymmetrical

Mandibular Canine Crown Outline (Incisal)

More symmetrical

Maxillary Canine Crown width (Incisal)

Slightly greater faciolingually than mesiodistally

Mandibular Canine Crown width (Incisal)

Much greater faciolingually than mesiodistally

Maxillary Canine Distal Half of Crown (Incisal)

Distal half of crown pinched in faciolingual

Mandibular Canine Distal Half of Crown (Incisal)

Distal crown faciolingual pinch not as evident

Maxillary Canine Cingulum (Incisal)

Centered

Mandibular Canine Cingulum (Incisal)

Often to distal

Maxillary Canine Incisal Edge

more horizontal mesiodistally

Mandibular Canine Incisal Edge

with distolingual twist

Distinct Feature of Maxillary Canine

Longest tooth in the mouth

Distinct Feature of Maxillary Canine

3rd longest crown (next to mandibular canine and maxillary central incisor)

Distinct Feature of Maxillary Canine

Widest buccolingual width among all incisors

Distinct Feature of Maxillary Canine

Least often extracted (together with the mandibular canine)

Distinct Feature of Maxillary Canine

3-lobed appearance

Distinct Feature of Mandibular Canine

Longest root (17.0 mm)

Distinct Feature of Mandibular Canine

Longest crown

Distinct Feature of Mandibular Canine

Oval-shaped and flattened M-D (deeper on distal).

Distinct Feature of Mandibular Canine

Anterior tooth most likely to have a bifurcated root.

Distinct Feature of Mandibular Canine

Only root that may be mesially inclined.
