Worksheet #4: Canines

Canines are the only teeth with _____ cusp(s) in the mouth

single

Mandibular canine is ______ from the midline

closer

The mandibular canine occludes with what two teeth?

lingual surface of the maxillary lateral and canine

Canine teeth are often called the _________ of the arch

Cornerstone

Max canine is the _________ and ______ root of any single rooted tooth in the mouth

longest; strongest

Max canine is the ______ tooth to be lost due to natural causes 

last 

The cusp of the Max canine is located over what structure?

Over the center of the root

On the Max canine the mesial cusp ridge is ______ than the distal cusp ridge 

shorter 

The mesial surface of the Max canine has what shape?

Flat shape

On the Max canine the distal outline is more _______ than the mesial surface

round

How many lobes does the Max canine develop from?

4 lobes, mesial lobe, central lobe, distal lobes, and cingulum

True or False: The Max canine has the largest cingulum of any tooth in the mouth 

True

Where is the mesial contact on Max canine?

In the incisal third and centered facial lingually

What structure separates the lingual fossa on the Max canine?

The lingual ridge which divides the lingual fossa to mesial lingual fossa and distal lingual fossa 

Define lingual ridge

a ridge that extends from the cusp apex to the center of the cingulum 

Where is the distal contact on Max canine

In the middle third of both incisal cervically and facial lingually

Max canine is wider __________ than mesial/distal

facial/lingually

True or False: Max canine is the longest tooth in the mouth

True

The length of the Max canine is

27 mm

On Max canine which side of the root has a depression 

distal side 

On Max canine the root shape is generally

straight

On Max canine the root apex has what shape?

blunt shape

On Max canine how many root canals

one

What is the size of the mandibular canine crown relative to all other crowns?

Mandibular canine crown is the longest crown in the mouth 

The mandibular canine is shorter by how much than the maxillary 

1mm

On Mand canine the mesial cusp ridge is ______ than the distal cusp ridge 

shorter 

 

What feature is much smaller in the mandibular canine than in the maxillary canine?

The cingulum in the mandibular canine is much smaller than the maxillary canine

Mand canine is wider in what dimension?

wider facial/lingually than it is mesial/distally

On Mand canine the root shape is _________ in a facial/lingually direction and more _______ mesial/distal

broader; narrower

Discuss proximal root concavity

Proximal root concavity is really deep that it separates the tooth into two separate roots. They are named according to the surface they are more closely to so facial/lingually root 

The mandibular canine is the only anterior tooth that occasionally has what feature?

two roots 

The apex of the mandibular canine root is _______ than the apex of the maxillary canine

sharper

Diamond shape wear pattern on Mand canine

Sometimes the cusp of the canine wears off making it look like a lateral incisor, so when it wears off it creates a diamond shape area on the incisal surface, and lateral incisor has a ribbon shaped pattern on the incisal surface, that’s how you can tell them apart is the cusp wears off

Mand canine: How can you best tell left from right

From the facial line angles, mesofacial line angle is sharper at the cervical of the crown than the distolfacial line angle which is rounded
