tooth features Flashcards
the buccal surface of this tooth has a pit with an increased risk of caries
lower first permanent molar
transverse fissure across the occlusal surface
lower first permanent molar
mesial root is broader than the distal root
lower second molars
lingual cusps are raised
lower second molar
convex labial surface
central incisor
disto incisal edge rounded
central incisor
scoop form to the crown on lingual side
central incisor
pronounced rounding of the disto incisal edge
lateral incisor
fossa on the palatal side of the tooth
lateral incisor
an elevation of enamel which forms mesial or distal margin of the lingual surface of an anterior tooth or the occlusal surface of a posterior tooth
marginal ridge
flat and symmetrical crown
lower central incisor
crown is slightly twisted on the root to follow the dental arch
lateral incisor
cingulum is divided into two shallow fossae on the palatal aspect by a ridge connecting the cusp
upper canine
root is usually grooved both mesially and distally
upper canine
root is more slender and symmetrical than its upper counterpart
lower canine
bulge of enamel on the cervical third of the lingual surface of all anterior teeth
cingulum
mesial border of cusp is shorter than disttal. labial surface is lingually inclined
lower canine
crown set in a straight line with the root when viewed proximally
upper canine
enamal extends further apically on the labial side than on the lingual side
lower canine
continuation of concavity from the mesial cervical region over to the cervical region of the root
canine fossa
oval, buccal cusp wider and higher than lingual cusp
upper first premolar
marked mesial displacement of the lingual cusp
upper first premolar
mesial marginal ridge is higher
upper first premolar
sharp fissure running mesiodistally, does not reach the distal marginal ridge, but extends mesially
upper first premolar
the mesial surface is more deeply grooved and has concavity in the cervical region
upper first premolar
marked distal curvature of the root
upper first premolar
two cusps similar in width and height due to reduction in buccal surface
upper second
mesial marginal ridge is more cervical
lower first premolar
curved buccal profile
lower premolars
