• 2

• 3

• 4

Which has more developed lingual marginal ridges, the maxillary or mandible?

• Maxillary

• Mandibular

Tertiary anatomy refers to the numerous grooves, pits, and lines

• True

• False

Which premolars are most likely to have two roots?

• Maxillary 1st premolar

• Maxillary 2nd premolar

If there is a root curvature, it generally is to the distal

• True

• False

Molars have between two and five cusps

• True

• False

Answer explanation

They have 3-5 cusps

The more posterior the position of the molar, the closer together the roots will be to each other

• True

• False

Answer explanation

Max 3rd molar often has fused roots.

When considering the CEJ during tooth identification the mesial surface typically has:

• Less curvature than the distal

• More curvature than the distal

• The same curvature as the distal surface
