The canine is the

cornerstone tooth

Why is the canine the cornerstone tooth?

It takes us from the anterior teeth to the posterior teeth

From the facial view, what shape is the canine?

Pentagon

Apically-incisally (from the tip of the root to the biting edge) the maxillary canines are the _________ teeth in the whole mouth

longest

Maxillary canines are larger than mandibular canines in all dimensions except

crown length

The mandibular canine has a ______ crown than the maxillary

longer

Maxillary canine crown is ____________ mesial-distally than that of a central incisor

narrower

Maxillary canine has a _______ root than the mandibular canine

longer

Maxillary canine has the _____ root to crown ratio

best

Canine has ______ incisal edges:

two; mesial and distal

The mesial slope is ________ than the distal slope

shorter

What shows greater development on teh facial view and creates a facial ridge?

The middle labial lobe

The middle lobe of the canine grows longer and gives it a

cusp

The cusp

helps the canine pierce the gum without issues

The cusp tip is in line with

the root's center

All anterior teeth come from ________ lobes

4

On the maxillary canine, we see shallow depressions, which divide the crown into

three lobes

We can see a well developed __________ going from the cusp tip to the cingulum

lingual ridge

The lingual ridge divides the lingual fossa

into two parts---mesial and distal fossae

Marginal ridges are

present

Cingulum is

centered and the largest of any anterior tooth (therefore all teeth)

Why does the maxillary canine have the largest cingulum of any tooth?

Only anterior teeth have cingulum

The mesial aspect of the maxillary canine is

greatest facial-lingually than any other anterior tooth

The facial ridge is

most prominent of any tooth

The facial ridge is the most prominent because

it gives the canine its self-cleansing property

developmental depression along the maxillary canine's root surface

helps it anchor itself into the bone

The distal developmental depression

is deeper than the mesial

maxillary canine are the

most stable teeth in the mouth

What makes the maxillary canine the most stable teeth in the mouth

its shape, which promotes cleanliness, and its root length

Incisally, the cusp tip is

buccal to teh crown's center F-L and mesial to the center mesio-distally

Because of the cusp tip's orientation

we can see more of the lingual view incisally

From the incisal view, the maxillary canine is

greater F-L than M-D

The insical view of the maxillary canine has the greatest

F-L dimension of any anterior tooth

The labial aspect of the canine is

convex (round), because the labial ridge is so prominent

However, the mesial half of the facial aspect is quite

convex

The distal side is

concave (think of a pinched cookie)

Root taper

towards the distal

Root shape

conical and blunted

Maxillary canine root

longer than any other tooth's root

Canine eminence

canines' form, position, and anchorage in the bone, and the bone ridge over the labial parts of the roots

canine eminence has _________ cosmetic significance

strong

canine guidance

helps guide teeth into the intercuspal position (like the tracks for a train)

Cross section shape

ovoid

How many roots and canals do maxillary canines have?

one root, one canal

in a cross section, the canine is wider

faciolingually

We can see a developmental depression in a cross secion

on both sides, but it's more evident on the distal

Mesial Contact Point

junction of middle and incisal 1/3

Distal Contact Point

center of the middle 1/3 (more cervical)

maxillary canine calcification beings

4-5 months

enamel is completed at

6-7 years

eruption happens

11-12 years

root completion happens

13-15 years
