quiz 2 morphology
premolars-molars
| Question | Answer |
|---|---|
| mesial cusp ridge of the bucaal cusp is longer than the distal cusp ridge | max first molar |
| has a nonfunctioning lingual cusp | mandibular 1st premolar |
| two premolars that most frequently have a groove crossing the mesial marginal ridge | max 1st premolar mandibular 1st premolar |
| has a depression in the cervial one third of the mesial side of the crown and root | maxillary first premolar |
| maxillary premolar that has the longer sharper buccal cusp | maxillary first premolar |
| largest maxillary premolar | maxillary first premolar |
| maxillary premolar that is most symmetrical from occlusal view | maxillary second premolar |
| two premolars without a central groove | mandibular 1st premolar mandibular 2nd premolar (3 cusps) |
| crowns tipped lingually with respect to the root axis line (proximal view) | mandibular 1st and 2nd premolars (both 2 and 3 cusp type) |
| from buccal view, crown is tipped distally from the root axis | mandibular 1st and 2nd premolars (both 2 and 3 cusp type) |
| mesial marginal ridge is more cervically located than its distal marginal ridge | mandibular 1st premolar |
| has no transverse ridge | mandibula 2nd premolar (3 cusps) |
| has the longer central groove | maxillary 1st premolar |
| has two major cusps almost the same size and length | maxillary 2nd premolar |
| has a central fossa | mandibular 2nd premolar (3 cusp) |
| premolars with only two fossae:both are trinagular fossae | maxillary 1st and 2nd premolars |
| has a central fossa and two triangular fossae | mandibular 2nd premolar (3 Cusp) |
| has a lingual groove | mandibular 2nd premolar (3 cusp) |
| mandibular premolar with the longest and sharpest buccal cusp | mandibular 1st premolar |
| mandibular molars | * |
| what grooves radiate out from the central fossa in a mandibular second molar | central, lingual, buccal |
| which cusp is the largest and longest on a mandibular 2nd | mesiolingual |
| which cusp may be absent on a mandibular first | distal |
| when the distal cusp is absent on the mandibular first, which grooves would not be present | mesiobuccal and distobuccal |
| which fossae are found on a mandibular first molar | mesial triangular, distal triangular, and central triangular |
| which developmental groove connects with the lingual groove running in the same direction on a mandibular sencond molar | buccal |
| from which view is only one root visiable on a mandibular 1st molar | mesial |
| which cusp triangular ridge does not meet to form a transverse ridge on a five-cusp molar | distal |
| which ridges form the boundaries of the mesial triangular fossa of a mandibular molar | triangular ridge of the mesiobuccal cusp triangular ridge of the mesiolingual cusp mesial marginal ridge |
| which two pairs of cusp triangular ridges make up or join to form the two transverse ridges on a mandibular 2nd molar | mesiobuccal mesiolingual distobuccal distolingual |
| list in sequential order the longest to shortest cusps on the mandibular 1st molar | mesiolingual distolingual mesiobuccal distobuccal distal |
| maxillary molars | * |
| which three grooves radiate out from the central fossa in a maxillary first molar | central, transverse groove of oblique ridge, buccal |
| which cusp on a maxillary first molar has two ridges: one that forms part of a transverse ridge and the other that forms part of an oblique ridge | mesiolingual |
| which cusp is the largest and longest ona maxillary second molar | mesiolingual |
| which cups is most likely to be absent on a maxillary second molar | distolingual |
| when the distingual cusp is absent which groove would not be present | distal oblique and lingual |
| of the four fossae on a maxillary first molar, which is the largest | central |
| from which view are only two roots visible on a maxillary first molar | mesial |
| which grooves are likely to radiate out of the mesial triangular fossa on the maxillary first molar | mesiobuccal fossa groove mesiolingual fossa groove mesial marginal ridge groove |
| which two cusps have the ridges that make up or join to form the oblique ridge on a maxillary molar | distobuccal mesiolingual |
| which two cusps have a triangular ridge that make up or join to form a transverse ridge on most maxillary molars | mesiobuccal mesiolingual |
| list in order the largest to smallest cusp area on the manillary first molar (occlusal view) | mesiolingual mesiobuccal distobuccal distolingual cusp of carabelli |
