occlusal patterns Flashcards
what tooth has a square shaped occlusal surface with. a cross shaped fissure
lower second molars
37, 47
what tooth has 5 cusps and on this tooth what cusp is the smallest
lower first molars (16, 26)
disto-buccal cusp is the smallest
what tooth has a triangle shaped occlusal surface due to a significantly reduced cusp and what cusp is reduced
upper second molars (17, 27)
disto-palatal cusp is greatly reduced maybe even absent
what tooth has a H shaped fissure pattern and a diamond shaped occlusal surface
upper first molars (16, 26)
what tooth may have a tubercle of carabele present and on what cusp would this be located
upper first molars (16, 26)
would be present on the palatal surface of the mesio-palatal cusp which is the largest in this tooth
On an upper first molar what cusps are the smallest and largest
smallest = disto-palatal , deep fissure separating it largest = mesio - palatal
on an upper second molar what cusps are the smallest and largest
smallest = disto - palatal (may even be absent) largest = mesio - palatal
what tooth has a groove running all the way from buccal to lingual surface
lower first molars
what tooth sees a fissure run mesio - distally then separate to run either side of a cusp
lower first molars , groove runs distally then branches either side of the small disto-buccal cusp
what is the largest cups on a lower second molar
mesio- buccal
what tooth sees its two cusps separated by a fissure that often extends over mesial marginal ridge but not the distal
upper first pre molars.
14, 24
what tooth has a fissure separating its two cusps mesio - distally but the fissure does not meet either marginal ridge
upper second pre molars (15, 25)
what tooth has a known broad distal contact point and a smaller mesial contact point
lower first pre molars
what tooth often has a groove extending from the mesial pit to the mesio-lingual surface
lower first pre molars
on a lower second pre molar what is the largest cusp
mesio- lingual
either one large cusp or 2 but messy lingual is the largest
