Maxillary Canines (#6 & #11) Flashcards
What dominates the incisal surface?
Cusp with its cusp apex centered to the long axis of the tooth
what are the size differences in cusp ridges?
shorter Mesial cusp ridge and longer distal cusp ridge . This happens because of the diffrence in location from the HOC on the mesial and distal
which side has higher HOC
mesial is closer to the height of cusp
HOC
mesial-incisal third; distal-middle third; facial and lingual-cervical third
mesioincisal and distoincisal angles are
rounded
mesial surface
relatively flat, tapering from HOC to cervical; the mesiobuccal line angle is sharp from incisal to cervical
distal surface
more rounded; distobuccal line angle starts sharp at the incisal and becomes rounded close to cervical (most reliable way to distinguish mesial from distal)
how many lobes are present on facial surface?
three lobes are present (mesial,central and distal), central is more developed.
developmental grooves?
two developmental grooves just like incisors
cervical line curved?
yes but not as prominent as incisors; the mesial curves closer to the incisal than distal
cingulum
makes canine wider buccolingually than mesiodistally, differently from the incisors
lingual ridge
extends from the cusp apex to the cingulum
what does the lingual ridge divides the tooth into
splits lingual fossa into mesial and distal lingual fossa
how does the tooth looks like from incisal view
mesial flatter and wider than the distal
whats unique about the root
longest root in the mouth resulting in the longest tooth in the mouth
