maxillary permanent canine -- 2

pulp chamber and roots

for root canals, what shape should be done for canines?

oval

how many pulp horns does the pulp chamber of a canine tooth contain?

it typically contains one

pulp cavity from mesio-distal section

• narrow pulp chamber

• root canal is long and tapers into the apical foramen

the pulp cavity from labiolingual section

• the pulp chamber is pointed incisally and almost triangular in shape

• root canal starts wide cervically until about the middle, and then it narrows to the apical foramen

at what aspect is the root canal wider?

it is wider at the labiolingual aspect

what is the average length of the tooth? what are minimum and maximum lengths? what is the range?

• average: 26.5

• maximum: 28.9

• minimum: 23.9

• range 5.8

the majority of canals in canines are what?

• 96.5% contain one canal

• only 3.5% contain two canals

what is the percentage of lateral canals in the canines?

24%

what is different percentages of root curvature in the canines?

• 39% are straight, which is the highest amount

• 32% are distally curved

• 0% are mesially curved

• 13% are labially curved

• 7% are lingually curved

• 7% are bayonet and gradually curved

canal is typically what?

they are typically straight, though some show a distal apical curve (32%)

what is the shape of the root cross-sectioned?

• in cervical and middle thirds, the canal is ovoid in shape

• in apical third, they are circular in shape at the apex

what can the lingual surface of a maxillary canine exhibit?

on rare occasions, they may exhibit a tubercle, which is near the most incisal level of the cingulum

when a tubercle is present, what is most often associated with it?

a lingual pit

what is root form subject to?

many variations. there may be several curvatures along its length

since the maxillary canine erupts after maxillary premolars, what are two scenarios that can happen?

• its space can become partially closed, leading it to erupt too closely to the labial or lingual surface of other teeth

• or it may not erupt at all. both of these cases are known as impacted teeth
