Answer: Two roots
The mandibular first molar normally has two roots — one mesial and one distal.
The oblique ridge is a landmark unique to which tooth?
Answer: Maxillary first molar
The oblique ridge of the maxillary first molar runs diagonally across the occlusal surface from the distobuccal cusp to the mesiolingual cusp.
Which permanent tooth has the longest root in the entire dentition?
Answer: Maxillary canine
The maxillary canine has the longest root of any tooth in the permanent dentition.
What is the name of the ridge that runs cervico-occlusally on the buccal surface of posterior teeth?
Answer: Buccal ridge
The buccal ridge is a vertical elevation running cervico-occlusally along the middle of the buccal surface of premolars and molars.
In the primary dentition, which tooth most closely resembles the permanent maxillary first molar in occlusal morphology?
Answer: Maxillary primary second molar
The maxillary primary second molar closely resembles the permanent maxillary first molar, including an oblique ridge and cusp of Carabelli.
