|
compare the M-D and F-L dimensions of max and mand premoalrs
|
max - wider F-L than M-D
mand - more similar M-D and F-L (F-L just slightly greater) |
|
|
compare the sizes of the F and L cusps in the max and mand premolars
|
max - F and L cusps more equal
mand - F cusps larger |
|
|
in which premolars is the occlusal table offset to the lingual?
|
mand
|
|
|
compare the facial and lingual HOC of the max and mand premolars
|
facial - HOC for both at cervical 1/3 but mand slightly more cervical
lingual HOC - mand slightly more occlusal than max |
|
|
compare the size of the cusps in the max 1st and 2nd premolar
|
in 1st the L cusp is shorter than the F cusp, in the 2nd the F and L cusps are more equal
|
|
|
which premolar has a mesial crown root concavity?
|
max 1st
|
|
|
which max premolar is the MB cusp ridge longer than the DB cusp ridge?
|
max 1st, the 2nd has more symmetrical M and D halves
|
|
|
compare the root depression in the max
|
1st - root depression greater on mesial
2nd - root depression greater on distal |
|
|
does the max 2nd have a mesial marginal groove and concavity like the 1st?
|
no
|
|
|
compare the facial proximal line angles in the max
|
1st - more angular
2nd - less angular |
|
|
in which max is the central groove longer and the M and D pits further apart?
|
1st
|
|
|
which max has the shortest mesial marginal ridge?
|
1st
|
|
|
which max how more lingual convergence and taper?
|
1st
|
|
|
compare the occlusal outline of the mand 1st and 2nd
|
occlusal outline of 1st more rounded (diamond shaped); occlusal outline of 2nd more squarish (more like a small molar)
|
|
|
compare the location of the facial cusp tip in the mand 1st and 2nd
|
1st - facial cusp tip in line w/ mid-line of root
2nd - facial cusp tip is fascial to root midline |
|
|
which premolar is the only premolar w/ no transverse ridge but w/ a lingual groove?
|
mand 2nd
|
|
|
in which premolar are the M and D contact areas the same?
|
mand 1st (mesial may be more cervical)
|
|
|
in which premolar is the central groove shallow or missing?
|
mand 1st
|
|
|
in the mand 2nd 3 cusp variety which L cusp is larger?
|
ML cusp larger than DL
|
|
|
which premolar has a M-L groove?
|
mand 1st
|
|
|
which premolar resembles a canine?
|
mand 1st
|
|
|
in which mand premolar is the occlusal table inclined lingually and most of the table is visible from the lingual?
|
mand 1st
|
|
|
in the mand 1st which marginal ridge slopes more?
|
M slopes more than D
|
|
|
which premolar has a central groove deeper than any other tooth?
|
max 1st
|
